Abstract
The utility model discloses a four-shaft bolt anti-loosening structure of a 6-ton loader gearbox, which comprises a four shaft, a shaft end baffle, a stop gasket, a bolt and a retainer ring; the four shafts are internally provided with a bearing and a flange, the end surface of an inner hole of the flange is provided with the shaft end baffle, and the shaft end baffle is locked on the end surface of the four shafts through two bolts; the inner hole of the stop washer is fitted with the head of the bolt and is arranged, and the stop washer and the head of the bolt are in interference fit to play a role in preventing the bolt from loosening; and a retainer ring groove is formed in the shaft end baffle and used for installing the retainer ring, and the retainer ring is attached to the end face of the stop washer after being installed so as to limit the stop washer from being separated. The utility model provides a prior art stop gasket assembly yielding, during the use the easy pine of locking gasket take off and cause the unable reuse's of locking gasket problem when the bolt is not hard up, the maintenance.
Description
Technical Field
The utility model relates to a bolt anti loosening structure of loader gearbox, concretely relates to 6 ton loader gearbox four-axis bolt anti loosening structure.
Background
At present, a four-shaft flange locking bolt of a gearbox of a 6-ton loader generally adopts a stop washer for locking, the stop washer is provided with two step holes, the inner diameter of each step hole is smaller than that of a bolt head, the stop washer is sleeved in the two bolt heads during assembly, and due to interference fit, the rotation of the bolt can be limited after assembly, so that a locking structure of the bolt is realized. But this four-axis flange locking bolt anti loosening structure has following defect: firstly, the stop washer is thin and easy to deform when the assembly is not standard, and the stop washer is easy to loosen during use, so that the bolt loosening fault is caused; secondly, the structure utilizes interference fit to ensure that the stop washer is not loosened, and when the stop washer is maintained, the stop washer cannot be reused because the inner hole is deformed without interference after being detached, so that the maintenance cost is increased.
Disclosure of Invention
The utility model aims at overcoming above-mentioned defect, provide a simple structure, preparation and maintenance cost are low, use safe and reliable's 6 ton loader gearbox four-axis bolt anti loosening structure to solve prior art stop the easy pine of gasket assembly yielding, during the use stop the gasket and take off and cause the bolt not hard up, the unable reuse's of maintenance time stop the gasket problem.
In order to achieve the purpose, the four-shaft bolt anti-loosening structure of the gearbox of the 6-ton loader comprises a four shaft 2, a shaft end baffle 4, a stop gasket 5, a bolt 6 and a check ring 7; the four shaft 2 is internally provided with a bearing 1 and a flange 3, the end surface of an inner hole of the flange 3 is provided with the shaft end baffle 4, and the shaft end baffle 4 is locked on the end surface of the four shaft 2 through two bolts 6; the inner hole of the stop washer 5 is fitted with the head of the bolt 6 and is arranged, and the stop washer and the bolt are in interference fit to play a role in preventing the bolt from loosening; and a retainer ring groove is formed in the shaft end baffle 4 and used for installing the retainer ring 7, and the retainer ring 7 is attached to the end surface of the stop washer 5 after being installed so as to limit the separation of the stop washer 5.
The four-shaft bolt anti-loosening structure of the gearbox of the 6-ton loader with the structure has the following technical characteristics and beneficial effects:
1. a stop ring groove is formed in the position of the shaft end baffle, after the stop washer is installed, the check ring is assembled to the stop ring groove, the check ring is attached to the end face of the stop washer, the stop washer is prevented from being separated in the actual working condition due to the fact that the assembly is not standard, and the failure rate is reduced;
2. the retainer ring structure is adopted to limit the stop gasket from coming off, so that the reliability of the gearbox is improved;
3. the stop washer is limited to be separated by the check ring structure, and can be repeatedly used during maintenance, so that the maintenance cost is reduced.
The utility model discloses 6 ton loader gearbox four-axis bolt anti loosening structure is through keeping off a circle groove in axle head baffle department increase, and the retaining gasket installation back, retaining ring assembly to keeping off a circle groove position, retaining ring laminating retaining gasket terminal surface make deviating from of retaining ring restriction retaining gasket, stop the phenomenon that the retaining gasket deviates from in the actual operating mode because of the assembly is irregular, and the retaining gasket is reusable when after-sales maintenance simultaneously, finally improves the gearbox reliability, reduces the maintenance cost, increases the income of enterprise.

Detailed Description
The following describes the four-shaft bolt anti-loosening structure of the gearbox of the ton loader according to the present invention in further detail with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1-2, the four-shaft bolt anti-loosening structure of the gearbox of the 6-ton loader of the invention comprises a four shaft 2, a shaft end baffle 4, a stop washer 5, a bolt 6 and a retainer ring 7; the four shaft 2 is internally provided with a bearing 1 and a flange 3, the end surface of an inner hole of the flange 3 is provided with the shaft end baffle 4, and the shaft end baffle 4 is locked on the end surface of the four shaft 2 through two bolts 6; the inner hole of the stop washer 5 is fitted with the head of the bolt 6 and is arranged, and the stop washer and the bolt are in interference fit to play a role in preventing the bolt from loosening; and a retainer ring groove is formed in the shaft end baffle 4 and used for installing the retainer ring 7, and the retainer ring 7 is attached to the end surface of the stop washer 5 after being installed so as to limit the separation of the stop washer 5.
During the assembly, after 5 installation at the locking gasket, retaining ring 7 assembles to the retaining ring groove position of axle head baffle 4, 5 terminal surfaces of retaining ring 7 laminating locking gasket, and what retaining ring 7 restricted locking gasket 5 deviates from, stops to cause locking gasket 5 to deviate from in the operating condition because of the assembly is not standard, and locking gasket 5 is repeatedly usable after sale simultaneously, finally improves the gearbox reliability, reduces maintenance cost, increases the income of enterprise.
