A loader wet drive axle housing

Abstract

This utility model discloses a wet drive axle housing for a loader, comprising an axle housing with an oil suction port located on the upper part of the axle housing and to the right rear of the axle housing. This utility model features a simple and compact structure, low manufacturing and maintenance costs, and reliable operation. It solves the problems of existing wet drive axle housings where the oil suction port is located below the oil level, resulting in long maintenance times when replacing the oil suction pipe, and oil leakage caused by casting defects or overload deformation of the oil suction port.

Description

Technical Field

[0001] This utility model relates to the field of loader drive axle technology, specifically to a wet drive axle housing for a loader. Background Technology

[0002] With the increasing standardization of underground mining operations, loaders operating in underground mining conditions generally adopt wet drive axles to meet mining safety certification and improve safety. A common type of wet drive axle housing for underground loaders features a forced-cooling oil suction port on the lower side of the housing. This port draws out gear oil from the drive axle, cools it through a radiator, and then returns it to the drive axle to lower the gear oil temperature. However, this drive axle housing structure has the following drawbacks: First, the oil suction port is located below the oil level, requiring the entire drive axle gear oil to be drained before replacing the suction pipe, otherwise leakage will occur, affecting maintenance efficiency. Second, because the oil suction port is located on the lower side of the housing, casting defects or overload deformation at the suction port can cause oil leakage. Summary of the Invention

[0003] The purpose of this invention is to propose a loader wet drive axle housing that is simple and compact in structure, low in manufacturing and maintenance costs, and reliable in use. This invention solves the problems of existing wet drive axle housings, such as the long maintenance time when replacing the oil suction pipe due to the oil suction port being located below the oil level, and oil leakage when the oil suction port has casting defects or is deformed due to overload.

[0004] To achieve the above objectives, the present invention provides a wet drive axle housing for a loader, comprising an axle housing 1, wherein an oil suction port 2 is provided on the axle housing 1, the oil suction port 2 being located on the upper part of the axle housing 1 and at the right rear of the axle housing.

[0005] The aforementioned wet drive axle housing for a loader, by designing the oil suction port on the upper part of the axle housing, has the following technical features and beneficial effects:

[0006] 1. The oil suction port of the wet drive axle of the loader is located at the upper right rear of the axle housing. The oil suction pipe is inserted from the oil suction port into the axle housing below the liquid level. With the oil suction port above the liquid level, there will be no gear oil leakage during installation and maintenance. Furthermore, oil leakage will not occur when the axle housing is under stress or has casting defects. This not only greatly reduces the failure rate of the drive axle, but also significantly improves maintenance efficiency and reduces maintenance costs. It solves the problems of long maintenance time when replacing the oil suction pipe in existing wet drive axle housings due to the oil suction port being located below the oil level, and oil leakage caused by casting defects or overload deformation of the axle housing oil suction port.

[0007] 2. It has a simple and compact structure, low manufacturing and maintenance costs, and reliable operation. Attached Figure Description

[0011] The following detailed description, in conjunction with the accompanying drawings, provides a further detailed embodiment of the wet drive axle housing for a loader according to the present invention.

[0012] Figure 1 , Figure 2 As shown, the present invention provides a wet drive axle housing for a loader, including an axle housing 1, and an axle housing oil suction port 2 on the axle housing 1. The axle housing oil suction port 2 is located on the upper part of the axle housing 1 and is located to the right rear of the axle housing.

[0013] During assembly, the oil suction pipe is inserted from the oil suction port 2 of the axle housing to below the liquid level inside the axle housing. Because the oil suction port 2 of the axle housing is located above the liquid level, there will be no gear oil leakage during installation and maintenance. Furthermore, oil leakage will not occur when the axle housing is under stress or has casting defects. This greatly reduces the failure rate of the drive axle and can significantly improve maintenance efficiency and reduce maintenance costs. It solves the problems of long maintenance time when replacing the oil suction pipe in existing wet drive axle housings due to the oil suction port being located below the oil level, and oil leakage caused by casting defects or overload deformation of the axle housing oil suction port.
