The Related Issues of Large Open Gear

According to several-year experience, Hongxing machine has been successfully developed new type ball mill and jaw crusher, in terms of some common sense in operating process, Hongxing experts give following advice in avoiding injuries of the open gear.

Scuffing is due to gear withstands large contact pressure or high tooth surface temperature, resulting in the lubricant film cannot be established; the uneven peak and valley in the tooth surface local get high-pressure welding when contacts, and then with the relative movement of the tooth surface, it promotes panel point plasticity deformation and rupture, resulting in the loss and migration of the tooth surface materials.

The polishing stage will to be end if tooth surfaces have sufficient contact proportion, when the tooth surface is with the basic conditions to form a good lubricating oil film. To create a good lubrication conditions, it is required a suitable lubricant to reduce gear wear, prevent the gear damage like abrasion, glue, plastic deformation or pitting, extend gear life and avoid causing the continued development of existing injury caused by improper lubrication. In order to prevent the emergence of the aforementioned various types of damage, it is required to select the lubricant with high viscosity, strong carrying capacity, good adhesion properties with extreme pressure additives, good wear resistance and adapt- to-higher tooth surface temperature to achieve the following purposes:

The plastic deformation of tooth are caused by tooth receives a large load. Plastic deformation of the tooth can be divided into two categories: plastic deformation of tooth body and plastic deformation of tooth surface. The former is due to the tooth materials stand stress superior to the elastic limit, the latter is also related to friction condition besides high stress.

Hongxing machine, which is specialized in ball mill and jaw crusher advices users paying attention on the above points so that they can take full use of machines in working process.
