What is a Service Factor ?
A: Gearboxes generally operate under variable loads, so it is much better to select gearboxes with a suitable work factor. The following table shows the different working coefficients. In cases where overload is applied momentarily to the gearbox and is driven by a combustion engine, the following coefficients will be multiplied by 1.2.
Where's the Electro Gear Boom?
A: ISO8579-1 can be used to measure sound and detect it as normal or abnormal . This is the standard used to determine the noise level of a gear. There are three things that should be taken into account when listening to an unusual sound from the gearbox:
1- The sound can be from a gearbox, depending on whether it is gear or bearing, and so on.
2- Sound can be from the gearbox and the consumer. Gear or belt coupling and gear or gearbox coupling should be checked.
3. Improper installation or replacement of the chassis is another reason for the unusual noise in the gearbox.
How to reduce gearbox noise?
A: The noise in gearboxes can be due to a variety of reasons : 1- Inadequate oil, 2- Gear fracture, 3- Bearing failure, 4- Extra load and 5- Incompatibility with electromotor and consumer
solutions Related reasons are as follows : 1- Removing dirty oil and adding oil, 2- Gear replacement, 3- Worn bearing replacement, 4- Reduction of gearbox size or replacement, and 5- Modification of gearbox assembly.
Bevel helical ( Bevel Helical ) What does it mean?
A: If the helical gearbox is intended to be non-linear and 90 degrees angular, the Gevia gear is called Bevel Helical . These gears can be straight or spiral.
Why use industrial gearboxes ?
A: Conventional electric motors are marketed with specific torque and torque. But many industries of the era require different speeds or torques. On the other hand, some devices may require rotation angle. Gearboxes have fulfilled these needs well and have made a special place in the industry today.
What is the ratio of torque to torque in an industrial gearbox ?
A: In an industrial gearbox, torque is inversely correlated; that is, an industrial gearbox can increase torque or decrease the torque output axis by reducing torque. Ideally, an industrial gearbox has a definite definition that states that the torque output at the torque, at the input and output of the gearbox, is constant, but since there is usually energy loss in mechanical devices, the output will be lower at the output axis. .
What are the important factors in choosing an industrial gearbox ?
A: There are several factors involved in choosing an industrial gearbox, such as the
type of machine selected, ambient temperature, ambient conditions such as dustiness, humidity, frost, drive motor (type and characteristics), type Transmission between engine and gearbox (direct, via coupling, belt and polar or variator), axle arrangement and radial load value.
How many industrial gearboxes are there?
Answer: Industrial gearboxes are generally classified into seven types:
1- Cochlear gearbox - Has a wide variety and is the most used. 2- Helical gearbox - It can be divided into different types of helical gearboxes with base flange and helical flange-driven helical gearboxes. 3. Solar gearbox (or planetary gearbox) - are the most efficient and have a special place in the industry today. Compound Gearbox - Compound gearboxes are generally used in places where very little distance is required. 5- Pendant gearbox 6- Crownville pinion gearbox- Rap gearbox
How is the output torque of the electro gearbox calculated?
Answer: There are many relationships to calculate the output torque of the electro gearbox, but as a simple equation, we can use the formula? = P × 955 / n² where the letter T is the torque sign, the letter P is the power sign , and the letter n دور is the far-end sign.
