Working environment and characteristics of roller shaft
Clicks:20148 Date:4-28
Roller shaft (sealing bearing) the actual operating temperature should be lower than the drop point 10-20 C. The use of synthetic grease should be lower than the temperature of 20-30.
This is due to the sealed bearings in accordance with the working temperature of the choice of grease, the main indicators should be drop point, oxidation stability and low temperature performance, drop point can generally be used to evaluate the high temperature performance.
Roller bearing parts in the use of the process, often appear to be damaged, usually due to the use of too long caused, there are other reasons. In order to avoid injury, it should be done in place. Right, conservative and stable will response to the bearing life of the machining process. With the deterioration of metallurgical technology, the quality of the original talent lost. The bearing is in the process of production, through a lot of cold and hot processing, in order to satisfy the small quantity, high frequency, high quality requirements, bearing steel should have good processing function. To solve the heat reaction and reject one-way thrust ball bearing quality and grinding of bearing force, and often has a more direct contact. As a result, the adoption of the stress can be reduced when the demolition of the shape, to ensure the removal function. Single rack on the loss of torque increased by 30 ~ 40%, one-way thrust ball bearing all the loss of torque increased by 50 ~ 65%. Roller bearing manufacturing parts to normal by forging, turning, grinding and heat treatment, such as multi-channel processing of disassembly. Thin wall bearing steel is in the form of the normal angle to reach the HRC61~65, the ability to make a one-way thrust ball bearings have a higher contact fatigue strength and wear resistance.
Roller bearing load select grease, grease for heavy load should be selected penetration small. In the high pressure work in addition to the needle penetration is small, but also have a higher oil film strength and extreme pressure performance. According to the environmental conditions to choose the grease, calcium based grease is not easy to dissolve in water, suitable for dry and less moisture environment.
Characteristics of roller
First, the roller and the adhesive tape between the basic realization of synchronous operation, wear and tear between each other is very small, to extend the service life of rubber belt and drive roller;
Two, the roller steel wrapped rubber tire wear layer, the anti-corrosion and wear resistance is greatly improved, bid farewell to the traditional roller weight, low precision, high resistance, abrasion resistance and easy to be damaged in and through the national hoisting machinery quality supervision and inspection center and the national type approval coal mining machinery quality supervision and inspection center of the inspection standard, achieved safety signs.
Three, with "clear roller" and the unique vertical labyrinth seal structure, the sealing performance of enhanced simulation test bench water test, water, dust test, spotless, and thoroughly prevent the pollution of sewage sludge on roller.
