Description

Rubber combined needle bearing for automobile steering system Technical Field The utility model relates to the technical field of bearings, in particular to a rubber combined needle bearing for an automobile steering system. Background Needle bearings (needle bearings) are roller bearings with cylindrical rollers, which are thin and long with respect to the diameter, the rollers are called needle rollers, the bearings still have higher load bearing capacity despite of smaller cross sections, the needle bearings are provided with thin and long rollers (the diameter D of the rollers is less than or equal to 5mm, the L/D is more than or equal to 2.5, and the L is the length of the rollers), so that the radial structure is compact, the inner diameter size and the load bearing capacity are the same as those of other types of bearings, the outer diameter is the smallest, the needle bearings are particularly suitable for supporting structures with limited radial installation size, along with the development of the automobile industry, the performance requirements on automobile parts are higher and higher, the performance of the bearings serving as key parts in an automobile steering system directly influences the automobile operability and safety, the traditional needle bearings are made of metal materials, and have higher bearing capacity and wear resistance, but in certain application occasions, such as an automobile steering machine, the bearings are required to have the characteristics of shock absorption, noise reduction, service life and the like, and the like. Certain limitations exist, for example, in applications where cushioning, shock absorption and high sealing performance are required. Through searching, the prior patent (CN 203926395U) discloses an elastic stamping outer ring needle bearing for a rubber combined needle bearing automobile steering system for an automobile steering system, wherein an inward pressing elastic ring is formed by a concave peripheral wall of the stamping outer ring, and when a mandrel is pressed into an inner hole of the needle bearing, the elastic ring enables a needle to be attached to the periphery of the mandrel, so that the zero clearance or small clearance requirement between the needle bearing and the mandrel is met, the possibility of slipping of an automobile steering wheel is reduced, vibration and noise are reduced, and the use safety and comfort of an automobile are improved. The elastic stamping outer ring needle bearing for the rubber combined needle bearing automobile steering system for the automobile steering system comprises a stamping outer ring, needle rollers and a retainer, wherein the retainer is arranged in the stamping outer ring, a plurality of mounting holes are formed in the retainer, the needle rollers are arranged in a space formed by the mounting holes and the stamping outer ring, the peripheral wall of the stamping outer ring is concavely inwards pressed into an elastic ring, and when the mandrel is pressed into an inner hole of the needle bearing, the elastic ring enables the needle rollers to be attached to the periphery of the mandrel so as to reduce a gap between the needle bearing and the mandrel. Further, the elastic ring is formed by arc-shaped inward concave outer surface and arc-shaped inward convex inner surface of the peripheral wall of the stamping outer ring, and after the mandrel is pressed into the inner hole of the needle bearing, the inward concave elastic ring is elastically deformed into a straight cylinder shape under the pressure of the mandrel, and the inner surface and the outer surface of the elastic ring are both in a horizontal column shape. The utility model has the advantages that the stamping outer ring peripheral wall is concaved inwards to form the elastic ring for pressing inwards, when the mandrel is pressed into the inner hole of the needle bearing, the elastic ring enables the needle to be attached to the periphery of the mandrel, and the zero clearance or small clearance requirement between the needle bearing and the mandrel is met, thereby reducing the possibility of slipping of the steering wheel of the automobile, reducing vibration and noise, and improving the use safety and comfort of the automobile. However, in the above-mentioned scheme, the whole installation structure is inconvenient to clean the inside and has limited deformation resistance. In view of the above, the utility model provides a rubber combined needle bearing for an automobile steering system.
