Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of a torque converter turbine shaft assembly for a loader, in particular to a torque converter turbine shaft supporting structure for a 3-ton loader. Background Art
[0002] 3-ton loaders have been widely used and favored by customers for their flexibility and certain tonnage of loading. On the other hand, customers have higher and higher requirements for the failure rate of 3-ton loader gearboxes. At present, the turbine shaft of the torque converter of 3-ton loaders generally adopts a cantilever structure supported by a single bearing. The defect of this single-support cantilever structure is that in actual application, when the torque converter has been used for a certain period of time, due to structural stability, the turbine shaft is prone to breakage. Summary of the invention
[0003] The utility model aims to provide a 3-ton loader torque converter turbine shaft double support structure which has a simple and compact structure, is easy to install, has low maintenance cost and is reliable to use, so as to solve the problem that the 3-ton loader torque converter turbine shaft in the prior art is easy to break after working for a certain period of time.
[0004] To achieve the above purpose, the utility model 3-ton loader torque converter turbine shaft double support structure includes a torque converter housing 1, an end bearing 2, a turbine shaft 3, a driving gear 4, a retaining ring 5, a bearing 6, a guide wheel seat 7, a bolt 8, a spring washer 9 and a turbine assembly 10; the torque converter housing 1 is provided with a mounting hole for the end bearing 2, and an assembly structure for the end bearing 2 is provided at the right end of the turbine shaft 3; the driving gear 4 is connected to the turbine shaft 3 by a spline and assembled between the end bearing 2 and the bearing 6; the bearing 6 is assembled in the guide wheel seat 7 and is limited at its right end by the retaining ring 5; the guide wheel seat 7 is fastened to the torque converter housing 1 by bolts 8 and spring washers 9; the left side of the turbine shaft 3 is connected to the turbine assembly 10, thereby forming a double support structure in which the turbine shaft is supported by the bearing 6 and the end bearing 2.
[0005] The above-mentioned 3-ton loader torque converter turbine shaft double support structure has the following technical characteristics and beneficial effects by improving the turbine shaft support method:
[0006] 1. On the basis of the existing torque converter structure, an end bearing 2 is added to the right end of the torque converter turbine shaft 3, and the support structure of the turbine shaft is changed from the original single bearing support to a double bearing support, which greatly improves the structural stability and solves the problem that the turbine shaft is easy to break after working for a certain period of time;
[0007] 2. Simple and compact structure, easy installation, low maintenance cost and reliable use. BRIEF DESCRIPTION OF THE DRAWINGS
