Compact locking and looseness-preventing device and dismantling tool thereof

Abstract

The invention provides a compact locking and looseness-preventing device and a dismantling tool thereof. The compact locking and looseness-preventing device comprises an oil guiding sleeve, an oil guiding body, a bearing, a chuck, a nut and a steel wire check ring. The oil guiding body and the bearing are sequentially installed on a central shaft of the oil guiding sleeve. The chuck and the steel wire check ring are located in the nut. The nut is connected with the end of the central shaft in a threaded mode. A fastening strip is fixed to the chuck through a second bolt in the dismantling tool. A baffle is located between the fastening strip and the end of the central shaft. A first bolt is connected with a threaded hole in the center of the fastening strip. According to the compact locking and looseness-preventing device and the dismantling tool thereof, axial movement and radial looseness of a fastened piece are prevented through mechanical structures respectively, the locking and looseness-preventing effect is excellent, the number of parts constituting the device is small, and both machining and maintaining are easy; meanwhile, the occupied axial space and the occupied radial space are small, and the device is particularly suitable for locking and looseness prevention of key parts in medium and heavy mechanical structures; all the parts of the dismantling tool can be machined and manufactured easily or directly purchased on the market, dismantling is easy and rapid, the usability of the tool is high, and failures are unlikely to happen.

Description

technical field [0001] The invention belongs to the technical field of mechanical design, and in particular relates to a compact locking and anti-loosening device and a disassembly tool thereof. Background technique [0002] With the development of mechanical transmission technology, mechanical components are developing towards high power density, especially the rapid development of large components, which also brings a series of problems, especially when the fastened components are inside the mechanical system, the early stage Do a good job in the necessary locking and anti-loosening work. After a period of work or running tests, in the middle and early maintenance, do not carry out large-scale disassembly work, the internal parts cannot be seen, and the anti-loosening problem cannot be verified, resulting in a lot of problems. If there is a large safety hazard, it is necessary to design a novel device with excellent locking effect to eliminate the whole safety hazard. [...

AI Technical Summary

Problems solved by technology

[0002] With the development of mechanical transmission technology, mechanical components are developing towards high power density, especially the rapid development of large components, which also brings a series of problems, especially when the fastened components are inside the mechanical system, the early stage Do a good job in the necessary locking and anti-loosening work. After a period of work or running tests, in the middle and early maintenance, do not carry out large-scale disassembly work, the internal parts cannot be seen, and the anti-loosening problem cannot be verified, resulting in a lot of problems. Large potential safety hazard, it is necessary to design a new type of device with excellent locking effect to eliminate the entire safety hazard

[0003] The traditional locking device often increases the tightening torque of the nut and cooperates with an ordinary stop washer. This locking and anti-loosening method has no structural pertinence, and the anti-loosening effect is poor in actual use.

When the vehicle encounters instantaneous shock and repeated vibration, the stop washer will fail to cut off, and the nut will also loosen, which will bring a huge safety hazard to the vehicle.
