推土机履带链和前惰轮总成
推土机配件厂家使用的产品也需要保养, 覆盖以增加产品的使用寿命, 提高其使用效果, 推土机履带链是非常关键的部件之一, 这 track chain for bulldozer, 我们应该采取什么样的维护措施?
对于推土机履带链,该环, 平时的保养不能太过过度, 但对润滑剂有一定的需求. 它具有优良的渗透性. 用于推土机链条, it is easier to lubricate the rollers and sprockets, but it is more difficult to lubricate the chain shaft and bushing. 所以, the lubricating oil must ensure good permeability, otherwise it can not play a good lubrication effect on the shaft and shaft sleeve. It need have excellent adhesion.
When the dozer track chain in operation, due to the role of high speed, the lubricating oil will be thrown off. At low speeds, the lubricating oil drips due to gravity. But no matter what kind of situation, or pollution of the environment, or waste lubricant, one-time requirements of good adhesion lubricant, and to be able to firmly adhere to the surface.
这 front idler assy is an important part of the chassis of construction machinery, which plays a guiding role in the work. 这 bulldozer track chain rail joint and the front idler assy are grinding, which requires the front idler to use high strength, high wear resistance and good impact performance. Heat treatment process plays a key role in the service life of the front idler assy.
As an important device of inductor heat treatment, the design and manufacturing quality of inductor directly affect the quenching quality. 这 front idler assy adopts the scanning heating quenching method. Two inductors are used for heating, one is for preheating, the other is for heating and cooling, and the front idler assy rotates at a certain speed. Sensors heat both upper and lower working faces.
The inductor is a copy inductor, on which a magnetic permeator is installed. The function of the permeator is to reduce the escape of magnetic field lines and improve the efficiency of the inductor. Improve the magnetic field distribution in the heating area of complex shaped workpiece to obtain even temperature distribution. The following points should be paid attention to during the design and production of inductor:
(1) The accuracy of the upper and lower two heating surfaces of the inductor should be controlled, which is the key to ensure the clearance between the upper and lower two working surfaces in the process of induction heating.
(2) The inductor is welded and calibrated and inspected with special birthgear to ensure that the size is within the required range.
(3) The inductor must be subjected to pressure test without water seepage. The water pressure should be above 0.3MPa for leakage test. Because for planar quenching induction heating, the general efficiency is low, the inductor heat is large, must have a good cooling to take away the heat, to ensure the life of the inductor.
(4) The magnetic body is tightly pasted, and the quantity of the two sides of the magnetic body is roughly the same, so as to ensure the same heating effect of the two working faces.
