Description

6 ton loader gearbox direct gear shaft gear dismantles frock

Technical Field

The utility model relates to the technical field of disassembly tools for parts of a gearbox of a drive axle of a loader, in particular to a disassembly tool for a direct gear shaft of a gearbox of a 6-ton loader.

Background

The development towards large tonnage is a trend in the loader industry, and 6-ton wheel loaders are increasingly favored by customers. Currently, a planetary gear type gearbox of a 6-ton wheel loader is generally adopted, and the interior of the gearbox mainly comprises a reverse gear, a first gear and a second gear, wherein the second gear is also called a direct gear. The structure has high reliability and high cost performance, and takes the dominant position in the market. Compared with a 5-ton wheel loader gearbox, the direct gear structure of the 6-ton wheel loader gearbox is optimized and improved, and the direct gear shaft gear is fixed on the first gear planet carrier by adopting two bearings and is of a double-support structure. Therefore, the disassembly tool is required to be developed and designed according to the characteristics of the direct gear structure so as to facilitate after-sales maintenance.

Disclosure of Invention

The utility model aims to provide the direct gear shaft gear disassembling tool for the 6-ton loader gearbox, which has the advantages of reliable quality, convenience and high efficiency in disassembling the direct gear shaft gear, avoidance of damage to other parts and low equipment maintenance cost.

In order to achieve the purpose, the direct gear shaft gear dismounting tool for the 6-ton loader gearbox comprises four bolts 1, a bottom plate 2, four reinforcing ribs 3 and a center bolt 4; the bottom plate 2 is a cross butterfly-shaped flat plate, a through hole is formed in the cross center of the bottom plate and used for installing the center bolt 4, and bolt holes used for being matched with the bolts 1 are formed in four corners of the bottom plate 2; the four reinforcing ribs 3 are respectively and vertically arranged on four sides of the bottom plate 2 and are positioned between the sides of the four threaded holes and the central bolt 4; the bottom plate 2, the reinforcing ribs 3 and the central bolts 4 are fixed into a whole through welding.

The bottom plate 2 is designed into a cross butterfly-shaped flat plate to lighten the quality of the disassembly tool, and the reinforcing ribs are additionally arranged beside the four threaded holes to improve the reliability of the disassembly tool structure.

When the tool is used, the center bolt 4 of the disassembly tool is screwed into the disassembly threaded hole of the direct shaft blocking gear 5, then the four bolts 1 are screwed into the threaded holes of the four corners of the bottom plate 2, the four bolts 1 are uniformly locked through a spanner or an electric air cannon, and the direct shaft blocking gear 5 is pulled out from the deep groove ball bearing 8.

The frock is dismantled to direct fender axle gear of 6 tons of loader gearboxes of above-mentioned structure has following technical characteristics and beneficial effect:

1. the structure is simple and reliable, the operation is convenient and efficient, the weight is light and the carrying is convenient;

2. the after-sales maintenance efficiency is greatly improved, and the situation that other parts are damaged due to other violent disassembly methods such as crowbars in the past is avoided.

Fig. 2 is a schematic top view of the direct gear shaft gear dismounting tool for the 6-ton loader gearbox.

Reference numerals: the device comprises a bolt 1, a bottom plate 2, a reinforcing rib 3, a central bolt 4, a direct gear shaft gear 5, a middle shaft output gear 6, a first gear planet carrier 7 and a deep groove ball bearing 8.

Detailed Description

The 7 ton loader transaxle wheel-side reducer gear set of the present utility model is described in further detail below with reference to the drawings and specific examples.

1-2, the direct gear shaft gear disassembling tool for the 6-ton loader gearbox comprises four bolts 1, a bottom plate 2, four reinforcing ribs 3 and a center bolt 4; the bottom plate 2 is a cross butterfly-shaped flat plate, a through hole is formed in the cross center of the bottom plate and used for installing the center bolt 4, and bolt holes used for being matched with the bolts 1 are formed in four corners of the bottom plate 2; the four reinforcing ribs 3 are respectively and vertically arranged on four sides of the bottom plate 2 and are positioned between the sides of the four threaded holes and the central bolt 4; the bottom plate 2, the reinforcing ribs 3 and the central bolts 4 are fixed into a whole through welding.

During operation, the center bolt 4 of the disassembly tool is screwed into the disassembly threaded hole of the direct shaft blocking gear 5, then the four bolts 1 are screwed into the four threaded holes of the disassembly tool bottom plate 2, then the four bolts 1 are uniformly screwed into by adopting a spanner or an electric air cannon, the four bolts 1 are propped against the middle shaft output gear 6, and the direct shaft blocking gear 5 is separated from the deep groove ball bearing 8 of the first gear planet carrier 7, so that the disassembly work is completed.

The tool for disassembling the gear of the direct gear shaft of the gearbox greatly improves after-sale maintenance efficiency, avoids the condition that other parts are damaged by other violent disassembling methods such as a crowbar, and the like, has simple and reliable structure, is convenient to operate and use, is light in weight and convenient to carry, and greatly reduces after-sale maintenance cost.
