Embodiment Construction

[0021] The rolling elements 9 of the one-way thrust bearing 2 include ball rollers, cylindrical rollers, needle rollers, tapered rollers and spherical rollers. figure 1 The shape of the rolling element 9 shown is spherical, and the best position of the one-way ball bearing is that the circle where the center of the ball is located is located between the inner holes of the bearing seats 6-1, 6-2 and the outer circle of the split ring 3 of the shaft groove.

[0022] like Figure 4 , Figure 5 As shown in the two semicircular shaft groove split rings 3, the width of the inner circle is greater than the width of the outer circle, and the two semicircular shaft groove split rings 3 are snapped into the grooves on the shaft 1 from two opposite directions ; The distance between the shaft groove and the surface opposite to the one-way thrust bearing 2 of the split ring 3 and the one-way thrust bearing 2 is maintained at 0.03 mm to 0.15 mm.

[0023] like Figure 6 The outer circle ...

Abstract

The invention discloses a structure utilizing a single direction thrust bearing. The structure comprises the single direction thrust bearing, a shaft, a bearing block and an axial assembly device, wherein the single direction thrust bearing is arranged on the shaft, and the single direction thrust bearing and the shaft are arranged in the bearing block together; the axial assembly device comprises an axial trough folio ring, lantern ring and an elastic damping ring structure for the shaft, and the single direction thrust bearing is limited on the shaft by the axial trough folio ring; and a certain gap is reserved between the axial assembly device and the single direction thrust bearing and between the single direction thrust bearing and the bearing block respectively. The structure in theinvention enables the single direction thrust bearing to bear bidirectional axial stress, has simple structure, is convenient in installation and saves cost.

Description

technical field [0001] The invention relates to a structure using a one-way thrust bearing. Background technique [0002] Thrust bearings are special bearings used to bear axial force, that is, bearings that bear force in a direction parallel to the shaft. Thrust bearings can only bear axial loads, and one-way thrust bearings can only bear axial loads in one direction. Two-way thrust ball bearings can bear axial loads in two directions; thrust bearings cannot limit the radial displacement of the shaft, and the limit speed is very low, one-way thrust ball bearings can limit the axial displacement of the shaft and the housing in one direction, two-way bearings Axial displacement in both directions can be limited. [0003] Generally, a structure bearing bidirectional axial force requires the use of a bidirectional thrust bearing, whose structure and installation are complicated and costly.
