what is Industrial Gearbox

Geared up in the dictionary, the Persian language means the gear box can be, but in the so-called one of the instruments transmission system power is among the motors (manufacturer of BE) and the Consumer be (like mixer machine, etc. تیکنر, etc.) are placed. The main task of the gearboxes make the change in the speed of rotation and torque required for use in various sectors of the industry, in other words, these machines, etc. after the engine or the way the fixtures industrial fall and can be low and high, than by the mechanism inside the gearboxes and torque needed for the device division.

Shailene mention the gearbox in the form of two categories of production are:

1. Gearbox reducer: this type of transmission between the actuator and the movable placed, and the distance required to meet, and in the brigade, and several are made. It is worth noting that most of the gearbox in this category are.
2. Gearbox multiplier: in some industries, energy production, for example, wind turbines and also in the industries up manually and refinery need to gearboxes to increase or round top to changes in speed and torque to achieve more speed with the torque less.

A variety of engine, gearbox, industrial

Gearboxes, industrial, different types are in the market to the name of the variety are known, some of which include:

1. Gearbox screw (Worm Gearbox)

The most commonly used and the most type of gearbox in the industry. This type of Gearbox, comprising of a ماردون steel that hard work steadily and folded rocks is a gear in the cochlea of sex frequently, bronze casting has been. Gearbox, helical (cubic) move سینماتیکی of the two pieces meet. In Gearbox, helical because of the structure and the angle of its output because of the orthogonal being has an abundance of and is due to the function of the software in lift systems, as well as elevators that need to create torque, and the soft launch is the application of abundance. Also, the gearbox, the درکانوایر upload systems material handling small application abundantly. Of the other important factors in the transmission of the cochlea, the lack of back flexibility in the ratio of converting the top 30. Other advantages of this gearbox, the ability to install in eight different modes, which makes the use comfortable, this gearbox are effortless.

2. Gearbox Helical or direct shaft (Helical Gearbox)

Gearbox Helical includes a number of the gear are, which has the structure of the Helix or Helical are and why this name are introduced. This type of gear from the category gear simple, but along the profiles diagonally towards along the shaft can be. Transmission in this type of gear box according to the structure of the wheel gear (The Helical) by moving a point along the surface of the gear is done. The gearbox due to the easing of the sound, and conflict software gears in the system, the power transmission to the process and can get away and be higher compared to the gears used are. Based on this type of transmission as the shape is cut away increases the torque on the output part are. The gearbox on the basis of type design in dimension, the average is placed, and usually to the electric motor that be between 0.35 to 55 kW coupling are.

Based on this type of transmission as the shape is cut away increases the torque on the output part are.

This gearbox is based on how to connect can be divided into three parts, the base, etc. flange and provided with both it divided.

3. Gearbox pendant (Parallel Shaft Gearbox)

Gearbox pendant due to the capability of multi-axis being the ability to create proportion, become high, which is parallel to this issue, the ability to create moments of high as well, and in cases where the need to torque, high functionality for permanent work can be, like the device of the mixer, or the systems of linear actuator in overhead cranes versatile selection is excellent .Gearbox pendant, like the gearbox هلیکال the structure of the wheel gear that stretches profiles diagonally towards along the shaft are only the first benefit is that has the structure of the multi-axial parallel can be. Also, this type of gear box due to a high volume of oil to the permanent basis, has a thermal capacity high compared to other gear boxes هلیکال that are in this that leads to a lifetime of function of the gearbox and the lack of destruction of the early gears can be.

4. گیربکس کرانویل پینیون (Crown Wheel Pinion Gearbox)

5. Gearbox, industrial Gearbox)

Some kind of Gearbox هلیکالی with the power, torque, very high, industrial gearboxes are. This gearbox in terms of appearance and performance to a single axis. multi axial., the Frog, etc., amateur, Russian and ran (Z) can be divided into. Usually industrial gearboxes based on the weight and delivers at least its weight is 400 kg.

Gearboxes, Industrial, according to the order of the consumer, and for single or coupled to the motor, which is the same engine, gearbox or electro gearbox can be produced.

6. Solar gear (Planetary Gearbox)

Nowadays, in light industry and heavy-duty to reduce or increase the round face high conversion ratio, and be very high in the space and efficiency, the top of the gearbox. this gearbox solar are used. Gears خوشیدی with the ability to use in a period of high be high, one of the most widely used gear in the industry trail have been introduced this type of gear in the two-Type single-stage or multi-stage design and can be manufactured.In this type of gearbox you get away, with an ideal range between 5/0 up to 800 rpm attainable can be. Conversion ratios in each class gearbox between 3 to 7 variables.

7.Geared variable speed

In some industries, the need is so far away electric motor without creating torque before entering the gearbox reduction or increase. The task of this work rests with a tool called a transmission round, is variable. Geared variable speed based on the type of design into the following categories can be:

• Geared variable speed belt Pully
• Geared variable speed واریاتور
• Gearbox, variable speed, hydraulic, usually the ratio of the circumference of this geared up to 1 to 5.

8.Geared extruder

Some sort of industrial gearboxes is that in industries extrusion performance. In part , gearbox, extruder description a more comprehensive offering.

Performance gearbox

Gearboxes machine that to transfer the BE Mechanical from a source of power to a consumer, and also meet the torque and speed of the rotational requirements of the consumer goes to work. Gearbox, in fact, an intermediary power source and the consumer can be that between the power source and the consumer, thereby creating flexibility can be.

Because being coordinated torque and speed rotational production source be with the consumer need to machine that this coordination as a mediator for the people, therefore, essential to appear the device that it wishes, it can meet the gearbox is called.

Simple machines devices that are no change in the amount of work, etc. do make it easy to live or, in other words, this species means a human, which enables to help low force heavy objects Terry would move the fixtures: levers, etc. reels, and. Crane., the gears etc can be. Below are some some of the factors effective in doing the work is described:

Work (W): if the point of impact is a force shift’t find say the work is done. So needed to do to two factors, The Force (F) and Shift (d) can be.

W = F × d (work)

Force (F): power factor that causes motion, change, move, or change the form, in objects to be crafted. Different objects and pieces of machinery may, in its units under the influence of forces, several used that value, along the direction and point of impact is also different. In such cases, the composition of the force, equivalent earn that alone could be the effect of all the forces have the power to force the combination of call.

Torque (τ): a force that wants a piece around a pivotal turn in the desired piece of produce torque can be.

Considering that the amount of work (W) is also multiplying the amount of force in the shift comes, therefore, torque and work can Common Units N. M, will have a but it should be noted that the amount of it in one piece, swivel, equal to, is not. For example, in the machine, limp, that with Force Constant can be applied torque remained constant, but the amount of work in proportion to the distance that the force during the works altered.

How to calculate output torque electro gear

τ=(P×9550)/ω

• τ: torque (Newton meters)
• P: power (kW)
• ω: round output (round per minute)

Components that make up the gearbox

1. Gear: gearbox are several components that are the most original, except it’s the gear can’t find that depending on the type of Gearbox, etc. shape and sex, it is different.
2. Shell gearbox: gears within it fall, and sex, it is usually of cast iron castings is.
3. Shaft, input and output: the shaft can be for the hole (Hollow) or shaft (Solid), have sex and it’s from steel.
4. بیرینگ (Bearing), or bearing: to bear the burden of radial and axial shaft of the gearbox are used.
5. Leak strap (Seal) or seal: for the protection بیرینگ from external factors like dust and also the maintenance of the oil inside the shell used.
6. Cap, oil control and overview
7. Seal

Standard industrial gearboxes

In 1943 the standard with the name of the AGMA421.01 for industrial gearboxes were offered. Using this gearbox can be the gearbox depending on the horsepower and the amount of tension allowed to measured. Also in the standard tips, especially heat treatment is also provided.

Standard AGMA 421.05 in 1963 with the changes the direction of the correction, the standard of the previous, and also for the development in how to design and acted gearbox was offered.

For example, in the gearbox هلیکال based on standard AGMA 421.05 we have:

• If the gearbox single-stage is the speed of the linear step ≥ m/s 35 and the speed of the rotational its RPM 4500 should be.
• If geared multi-stage is, in at least one stage, the linear speed step ≥ m/s, 35 and in the other stages should not be less than 8 m/s.

How to maintenance gearbox

Based on the type of gearbox and ambient conditions, etc. for prolonging the useful life of those actions are done. For example, in the solar gear, etc. visit the oil level should be periodically and in a short time, be. For the notice of the conditions of maintenance to the catalogue of the device, please refer.

The concept of clearance in the gearbox

The empty space between the two gear engaged clearance (Backlash) say. This clearance can be both static and dynamic is. If merely wobble absolute measure, be it Mobility, static, and if the difference between the force of transitional calculate crafted in. clearance to dynamic or Dynamic say.

Usually in between a variety of gear because of the easy the process of making and machining, based on standard build, clearance there. Space clearance existing between the gear can be used with the oil, cover the alliance. Oil in addition to cooling parts, thereby reducing the friction between the gears can be.

History the construction of Gearbox

Historical evidence suggests the people of ancient Greece, decorative objects, similar to the gear today is made of wood, was made with animal fat, the contact surface between the couple, the ribs lubrication lived. With this tool, heavy objects, such as materials pasted or for the transfer of water from one level to the other, they used.

Gearbox today, in fact, from the eighteenth century AD, concurrent with the industrial revolution in England, and in the textile industry were made. Although the gear modern advances many of the examples of the past, but it is surely in the future, a new generation of gearbox with better capabilities, and with the proper dimensions more there will be.
