Abstract
Title: A Mounting Structure for Bearing on Small-diameter Shaft Abstract The invention relates to a mounting structure for a bearing on a small-diameter shaft, which belongs to the technical field of bearing mounting structures. The mounting structure comprises the shaft and the bearing mounted on the shaft, wherein the outer diameter of the part for mounting the bearing of the shaft is smaller than the hole diameter of an inner ring of the bearing, a shaft sleeve is arranged between the inner ring of the bearing and the shaft, an inner hole of the shaft sleeve is in close fit with the shaft, and the outer wall of the shaft sleeve is in close fit with the inner ring of the bearing. The mounting structure is convenient to mount and lower in manufacturing cost, and can ensure that the bearing has sufficient supporting strength, and solve the problems that when the difference between the outer diameter of the shaft and the hole diameter of the inner ring of the bearing is great, if the diameter of the shaft is increased to meet the fit with the bearing, the situation is bound to cause higher manufacturing cost of the shaft and larger volume of the shaft; if the size of the bearing is reduced to be fitted with the shaft, the supporting strength of the bearing may be insufficient and the like in the prior art.

Description
Description A Mounting Structure for Bearing on Small-diameter Shaft Technical Field The invention relates to a mounting structure for a bearing on a small-diameter shaft, which belongs to the technical field of bearing mounting structures. Background of the Invention Under certain situations, the difference between the size of a bearing and the size of a shaft is greater, that is the hole diameter of an inner ring of the bearing is greater than the outer diameter of the shaft, thereby bringing convenience to mounting. If the diameter of the shaft is increased to meet the fit with the bearing, the situation is bound to cause higher manufacturing cost of the shaft and larger volume of the shaft; if the size of the bearing is reduced to be fitted with the shaft, the supporting strength of the bearing may be insufficient. Summary of the Invention The invention aims at providing a mounting structure for a bearing on a small-diameter shaft, which is convenient to mount and lower in 1 manufacturing cost, and can ensure that the bearing has sufficient supporting strength, and solve the problems that when the difference between the outer diameter of the shaft and the hole diameter of the inner ring of the bearing is great, if the diameter of the shaft is increased to meet the fit with the bearing, the situation is bound to cause higher manufacturing cost of the shaft and larger volume of the shaft; if the size of the bearing is reduced to be fitted with the shaft, the supporting strength of the bearing may be insufficient and the like in the prior art. The above technical purpose of the invention is mainly solved through the following technical scheme: the mounting structure comprises the shaft and the bearing mounted on the shaft, wherein the outer diameter of the part for mounting the bearing of the shaft is smaller than the hole diameter of an inner ring of the bearing, a shaft sleeve is arranged between the inner ring of the bearing and the shaft, an inner hole of the shaft sleeve is in close fit with the shaft, and the outer wall of the shaft sleeve is in close fit with the inner ring of the bearing. The shaft sleeve is arranged between the outer wall of the shaft and the inner ring of the bearing, on the one hand, the problem that the difference between the outer diameter of the shaft and the hole diameter of the inner ring of the bearing is great can be solved, on the other hand, the diameter of the shaft can be kept unchanged, and the sufficient supporting strength of the bearing can be simultaneously ensured. 2 Preferentially, a radial outer convex ring is formed at one end of the shaft sleeve, and the radial outer convex ring pushes against the end surface of the inner ring of the bearing. The radial outer convex ring on the shaft sleeve can prevent axial movement between the bearing and the shaft sleeve, and play a role of axially positioning the bearing. Preferentially, the axial length of the shaft sleeve is equivalent to the height of the inner ring of the bearing. Preferentially, the shaft sleeve and the shaft are injection-molded into a whole, on the one hand, the reliable fit between the shaft sleeve and the shaft can be ensured, on the other hand, the assembly between the shaft sleeve and the shaft can be simplified. Therefore, the invention has the characteristics of being convenient to mount, being lower in manufacturing cost, being capable of ensuring that the bearing has sufficient supporting strength and the like. Brief Description of the Drawings Figure 1 is a schematic diagram of structure of the invention; Figure 2 is a local amplified view of A part in Figure 1. Detailed Description of the Invention In combination of the figures, the technical scheme of the invention is 3 further specifically described through the following embodiment. Embodiment 1: as shown in Figure 1 and Figure 2, a mounting structure for a bearing on a small-diameter shaft comprises the shaft 1 and the bearing 2 mounted on the shaft 1, wherein the outer diameter of the part for mounting the bearing 2 of the shaft 1 is smaller than the hole diameter of an inner ring of the bearing 2, a shaft sleeve 4 is arranged between the inner ring 3 of the bearing 2 and the shaft 1, the shaft sleeve 4 and the shaft 1 are injection-molded into a whole, the outer wall of the shaft sleeve 4 is in close fit with the inner ring of the bearing 2, a radial outer convex ring 5 is formed at one end of the shaft sleeve 4, the radial outer convex ring 5 pushes against the end surface of the inner ring 3 of the bearing 2, and the axial length of the shaft sleeve 4 is equivalent to the height of the inner ring of the bearing 2. The shaft sleeve is arranged between the outer wall of the shaft and the inner ring of the bearing, on the one hand, the problem that the difference between the outer diameter of the shaft and the hole diameter of the inner ring of the bearing is great can be solved, on the other hand, the diameter of the shaft can be kept unchanged, and the sufficient supporting strength of the bearing can be simultaneously ensured. 4
