Dozer Track Chain And Front Idler Assy

Bulldozer accessories manufacturers use products also need to be maintained, cover to increase the service life of the product, improve its use effect, the dozer track chain is one of the very key parts, the track chain for bulldozer, what kind of maintenance measures should we take?

For the dozer track chain this ring, the usual maintenance can not be too excessive, but there is a certain need for lubricant. It has excellent permeability. For bulldozer chains, it is easier to lubricate the rollers and sprockets, but it is more difficult to lubricate the chain shaft and bushing. Therefore, 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.

The front idler assy is an important part of the chassis of construction machinery, which plays a guiding role in the work. The 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. The 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.
