Problems solved by technology

However, due to the large amount of deformation of the plastic cage during assembly, plastic deformation may occur
In addition, during the assembly process, due to the contact and extrusion between the cage and the inner diameter edge of the outer ring, it is easy to wear and there is a risk of material falling, which may affect the cleanliness of the bearing

Embodiment Construction

[0039] Figure 1 to Figure 4 A cage 10 according to a first embodiment of the invention is shown. In this embodiment, the cage 10 is used for a spherical roller bearing. The spherical roller bearing also includes at least an outer ring 2 , an inner ring 3 and rolling elements 4 .

[0040] figure 1 A perspective view of the cage 10 according to the first embodiment is shown. like figure 1 As shown, the cage 10 is designed as a window cage, which comprises two substantially ring-shaped and coaxially arranged ring parts, namely a large-diameter ring part 11 with a larger diameter and a small-diameter ring part with a smaller diameter. part 12, the cage 10 also includes a plurality of connecting parts 13 uniformly distributed in the circumferential direction, and the connecting part 13 connects the two annular parts 11, 12. The two ring parts 11 , 12 and the two adjacent connecting parts 13 enclose a pocket for guiding the rolling bodies. In this embodiment, the number of po...

Abstract

The invention relates to a holding frame, a bearing and an assembling method. The holding frame is applied to the bearing provided with an outer circle, wherein the radial inner side of the outer circle has the minimum inner side diameter; the holding frame comprises two annular parts, and a plurality of connecting parts which are connected to the two annular parts; the two annular parts and the connecting parts form pocket holes; an assembling area is formed in the radial outer side of each annular part; and the radial size of the holding frame in the assembling area is not greater than the minimum inner side diameter of the outer circle, so that the holding frame can be assembled to the radial inner side of the outer circle through the assembling area. The bearing comprises the abovementioned holding frame. The assembling method is used for assembling the holding frame to the radial inner side of the outer circle of the bearing. The assembling method comprises the following steps: a, inserting the assembling areas of the holding frame to the minimum inner side diameter of the outer circle, wherein a central axis of the holding frame and a central axis of the outer circle basically form an angle of 90 degrees; and b, rotating the holding frame until the holding frame and the outer circle are coaxially arranged.

Description

technical field [0001] The invention relates to the technical field of bearings. In particular, it relates to a cage for a bearing and the bearing itself comprising the cage. The present invention also particularly relates to an assembling method for assembling the above-mentioned cage on the radially inner side of the bearing outer ring. Background technique [0002] When the self-aligning function is required and the deflection of the shaft and / or the deviation of the bearing seat needs to be compensated, bearings such as spherical roller bearings or drum roller bearings can usually be used. Spherical roller bearings have two rows of spherical rollers, the outer ring has a common concave spherical raceway, and the inner ring has two concave raceways inclined at a certain angle to the bearing axis. For example, documents WO2010007979A1 and US10036423 respectively disclose a spherical roller bearing. Drum roller bearings are single-row self-aligning roller bearings. The r...
