Description

Loader double-change assembly four-shaft bearing limiting structure

Technical Field

The utility model relates to a loader is two to become assembly four-axis assembly, concretely relates to loader is two to become assembly four-axis bearing limit structure.

Background

The loader dual-variable assembly is one of the core transmission components of the loader, and can convert the mechanical energy of an engine into hydraulic energy and reduce the hydraulic energy into mechanical energy; the automatic speed-regulating mechanism can automatically regulate output torque and rotating speed, so that the loader can automatically regulate speed and traction according to road conditions and working conditions to adapt to various continuously-changing working conditions. The torque of the double-variable assembly is output to a front driving axle and a rear driving axle through a front flange and a rear flange by the four-shaft assembly, and a brake disc and a parking brake are installed at the front flange ends of the four shafts, so that the stress is more complex in actual working, the ball bearing at the position is easily damaged, and the double-variable assembly cannot work, so that the reliability of equipment is reduced, and the service life of the equipment is prolonged.

Disclosure of Invention

The utility model aims at overcoming above-mentioned defect, provide a simple structure, preparation and maintenance cost low, use reliable longe-lived two assembly four-axis bearing limit structure that become of loader to solve among the prior art because brake disc and parking brake are installed to the front flange end of four-axis, very easily cause this position ball bearing to damage because of the atress is complicated during the operation, lead to two problem that become the unable work of assembly.

In order to achieve the purpose, the four-shaft bearing limiting structure of the double-variable assembly of the loader comprises a box body, a left retainer ring, a ball bearing, an output shaft, an output gear, a right retainer ring, a front flange, a four-shaft gasket and a rear flange; two sides of the output shaft are fixed on the box body through a bearing at the left rear flange end and a bearing at the right front flange end, wherein the bearing at the left rear flange end is a ball bearing; the inner ring of the ball bearing is limited by an output shaft step and a rear flange, the outer ring of the bearing at the right front flange end is limited by a right retaining ring, and the inner ring of the bearing at the right front flange end is limited by an output gear, a four-axis gasket and a front flange; the method is characterized in that: the bearing at the front flange end on the right side is a cylindrical roller bearing so as to improve the bearing capacity and reliability of the bearing; a limiting step is arranged at the right side of a bearing hole of the box body at the left rear flange end to offset the axial force generated by the cylindrical roller bearing at the right front flange end of the output shaft; and the outer ring of the ball bearing at the rear flange end at the left side is limited and fixed by a left retainer ring and a limiting step.

The loader double-variable assembly four-shaft bearing limiting structure with the structure has the following technical characteristics and beneficial effects:

1. the bearing at the front flange end on the right side of the output shaft is changed into a cylindrical roller bearing by a ball bearing, so that the bearing capacity and reliability of the bearing are well improved.

2. The right side of the bearing hole at the left rear flange end of the box body is provided with a limiting step, the outer ring of the ball bearing at the left rear flange end is limited and fixed through a left retainer ring and the limiting step, and the axial force generated in the working process after the bearing at the right front flange end of the output shaft is changed into a cylindrical roller bearing through the ball bearing can be well offset, so that the product quality and the service life are well improved.

Adopt the two assembly four-axis bearing limit structure that become of loader of above-mentioned structure, solved because brake disc and parking brake are installed to the front flange end of four-axis, the atress is more complicated when the actual work, very easily causes this position ball bearing to damage, leads to the unable trouble of work of two assembly that become, has promoted product quality greatly, has improved equipment reliability and life.
