What should be attention to when purchasing a gearbox?
Dec 24, 2018

When we purchase a gearbox, we definitely need to consider many aspects, in order to avoid unnecessary problems in the later use, then what factors should we pay attention to in the purchase?

First, in the selection of geared motor equipment, we must consider the following factors:

1. The requirements of the working machine for the structure and dynamic parameters of the gearbox, such as structural size, quality, speed, efficiency, gear ratio, load characteristics, etc.

2, the working machine on the performance requirements of the gearbox: such as: work reliability, service life, noise, temperature rise and transmission accuracy.

3. Advanced, rational, economical, and universal interchangeability of gearbox technology.

4. The advanced, rational, economical and high reliability of the gearbox technology.

Second, the basic forms of gear damage during work are mainly divided into five categories: wear, tooth surface fatigue, gluing, plastic deformation and gear breakage.

1. Gear wear refers to the process of constant friction and consumption of the surface material of the gear during the meshing process. Gear wear can be divided into many types of wear and various degrees of wear. According to the gear wear damage mechanism, it can be divided into adhesive wear, abrasive wear, surface fatigue wear, corrosion wear and the like. According to the depth of wear, it can be divided into three types: slight wear, medium wear and excessive wear.

2.The tooth surface glues and scratches the metal of the two tooth surfaces of the gear, the glue wear occurs directly under a certain pressure, and there is relative movement after the "welding", the metal is torn off from the tooth surface or from one tooth to the other A phenomenon in which a tooth surface is transferred to cause damage. The macroscopic feature of gluing wear is that the tooth flanks exhibit strip-like rough grooves with different depths and widths along the sliding speed direction.

3.The tooth surface contact fatigue, the gear in the process of engagement, both relative rolling and relative sliding. The action of these two forces causes the shear stress of the pulsating cycle to change deep in the surface layer of the gear. Under the repeated action of the shear stress, the gear teeth cause local metal spalling and damage.
