Fastening device for preventing water pump lower bearing from being loosened

Abstract

The invention discloses a fastening device for preventing a water pump lower bearing from being loosened. The fastening device comprises a lower fastening device, a lower fastening device clamping groove, fastening threads, a lower fastening device linear inserting opening, a connector chamfer, an upper fastening device, an upper fastening device linear inserting opening and threaded grooves; thefastening threads are arranged in the lower fastening device in a lathed mode, and the threaded grooves are machined between the fastening threads; the connector chamfer is arranged on the lower partof the lower fastening device, and the upper fastening device is mounted above the lower fastening device; and the upper fastening device linear inserting opening is machined in the upper part of theupper fastening device, and the lower fastening device linear inserting opening is machined in the upper part of the lower fastening device clamping groove. According to the fastening device, design is simple, manufacturing is reasonable, the fastening device is not modified too much, the structure is compact, the phenomenon that shaft sleeve nuts are loosened when being subjected to rotating force and friction force is effectively prevented, the problem of loosening of the double nuts is solved better, stainless steel pins are adopted, and thus the fastening device is not prone to rusting inwater, resistant to corrosion, and convenient to mount and fold.

Description

technical field [0001] The invention relates to the technical field of anti-loosening of lower bearings of water pumps, in particular to a fastening device for preventing the lower bearings of water pumps from coming back loose. Background technique [0002] The most important part of the water pump is the bearing. The lower bearing of the bearing is particularly important. During the use of the water pump, the lower bearing is easy to loosen and cannot be fixed effectively, resulting in great losses. Therefore, the lower bearing of the water pump Anti-loosening plays a key role. The bearings under the water pump are fixed. Originally, double nuts are used to fasten the bearings to prevent back-loosening, which can easily cause the shaft sleeve to fall off and cause product quality accidents. [0003] In view of the above shortcomings, it is necessary to design and develop a fastening device for preventing the lower bearing of the water pump from coming back loose, which can...

[0002] The most important part of the water pump is the bearing. The lower bearing of the bearing is particularly important. During the use of the water pump, the lower bearing is easy to loosen and cannot be fixed effectively, resulting in great losses. Therefore, the lower bearing of the water pump Anti-loosening plays a key role. The bearing is fixed under the water pump. In the past, the double nut fastening method has been used to prevent loosening. It is easy to cause the shaft sleeve to fall off and cause product quality accidents.
