[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an anti-loosening guide bearing spring retaining ring, comprising a retaining ring body, the retaining ring body is a spiral body formed by superimposing and connecting a plurality of spring rings, and an elastic mechanism capable of promoting the separation of the spring rings is provided between the mutually contacting cross sections of the plurality of spring rings.
[0007] By adopting the above technical solution, when the bearing operates normally, the multiple circlips are squeezed, the elastic mechanism is in a contracted state, and the multiple circlips fit together to firmly position the bearing; when looseness occurs between the bearing and the spring retaining ring, the elastic mechanism will adaptively open the circlips to a certain distance and fill the gap caused by the looseness, so that the bearing can still maintain stable operation, thereby extending its service life.
[0008] The above technical solution is further configured as follows: the elastic mechanism includes a mounting groove provided on one of the upper and lower cross sections of the circlip and an elastic strip installed in the mounting groove, and the thickness of the elastic strip is greater than the depth of the mounting groove.
[0009] By adopting the above technical solution, when the circlips are squeezed and fit together, the other cross section of the circlip opposite to the installation groove squeezes the elastic strip to make it shrink; when looseness occurs between the bearing and the spring retaining ring, the elastic force of the elastic strip separates the circlips by a certain gap to fill the gap caused by the looseness, so that the bearing can still maintain stable operation.
[0010] The above technical solution is further configured as follows: the installation groove is interference-fitted with the elastic strip, and the installation groove is a right-angle groove or an oblique-angle groove with a tightened opening.
[0011] By adopting the above technical solution, the elastic strip is pressed into the installation groove by interference fit, so that the elastic strip will not fall off; the installation groove is set as an angled groove with a tightened opening, which can make the elastic strip more firmly installed than a right-angle groove.
[0012] The above technical solution is further configured as follows: a limiting groove capable of loosely matching with the elastic strip is provided on another cross section of the circlip opposite to the mounting groove, guiding inclined surfaces are provided at both ends of the limiting groove opening, and the thickness of the elastic strip is greater than the sum of the depths of the mounting groove and the limiting groove.
[0013] By adopting the above technical solution, a limiting groove is provided on another cross section of the spring ring opposite to the installation groove, so that the elastic strip can be limited, thereby reducing the risk of radial dislocation of the elastic strip due to extrusion; the guiding inclined surface can make it easier for the elastic strip to be inserted into the limiting groove.
[0014] The above technical solution is further configured as follows: positioning holes are provided at both ends of the retaining ring body, and positioning protrusions that transitionally match the positioning holes are provided at positions of the spring ring corresponding to the positioning holes.
[0015] By adopting the above technical solution, the two ends of the retaining ring body can be limited by the cooperation of the positioning hole and the positioning protrusion, so as to further avoid radial misalignment during extrusion.
[0016] The above technical solution is further configured as follows: the positioning hole is configured as a long strip.
[0017] By adopting the above technical solution, the positioning hole is set to be a long strip, so that during disassembly, the end of the retaining ring body can be easily pulled out through the positioning hole with the help of a tool.
[0018] The beneficial effects achieved by the utility model are: it can prevent the bearing from loosening, improve the running stability, and thus prolong the service life. BRIEF DESCRIPTION OF THE DRAWINGS
