Abstract

The utility model relates to a split bearing comprising a bearing outer ring, an inner ring, a rolling body and a retainer. The utility model is characterized in that the outer ring, the inner ring and the retainer are butted by two semi-circles; clamping rings are arranged out of the inner ring; two semi-clamping rings are fastened by a bolt; two semi-retainers are connected by a spring sheet; the spring sheet is connected with the retainer by a fastening nail. The outer ring, the inner ring and the retainer of the utility model are made by two semi-circles, which is convenient for bearings using the installation and the maintenance of crankshafts, long shafts or eccentric shafts.

Description

Split bearing

The utility model is a kind of bearing, is a kind of split bearing specifically.

The bearing of using in the present mechanical industry is solid bearing mostly, and the inner ring of bearing and outer ring are full circle shapes, will be by an end suit of axle during installation.This bearing is installed and keeped in repair for major axis, bent axle and the eccentric shaft of main equipment is very inconvenient.

The purpose of this utility model provides a kind of split bearing, and it can overcome existing shortcoming in the prior art, and is easy for installation, and long service life.

The purpose of this utility model is achieved in that it comprises bearing outer ring, inner ring, rolling element and retainer, it is characterized in that outer ring, inner ring and retainer are two semicircle butt joints and form, inner ring is equipped with clamping ring outward, use bolton between two and half clamping rings, two and half retainers link to each other with spring sheet, connect with clench nail between spring sheet and the retainer.

The utility model is made two semicircle forms with the inside and outside circle and the retainer of bearing, make bearing when being used in bent axle, major axis or eccentric shaft installation and keep in repair more convenient.

Original bearing is that inner retaining side is located on the inner ring, if but the inner retaining side of bearing is located on the clamping ring of bearing, can conveniently process the working life that can improve bearing simultaneously.

Below in conjunction with embodiment and accompanying drawing thereof the utility model is described in further detail.

Fig. 1 is a structure cut-away view of the present utility model.

Fig. 2 is embodiment two a partial sectional view.

Fig. 3 is the schematic representation of the spring sheet shown in Fig. 1.

Fig. 4 is the left diagrammatic sketch of Fig. 3.

1 is the outer ring among the figure, the 2nd, and clamping ring, the 3rd, inner ring, the 4th, rolling element, the 5th, retainer, the 6th, retainer lid, the 7th, spring sheet, the 8th, screw, the 9th, spring pin, the 10th, screw.

With reference to Fig. 1, d * the D of bearing shown in the figure * H is 200 * 368.3 * 156.369 (mm), the inner ring 3 of bearing is to be formed by two semicircle butt joints, two clamping rings 2 are housed in its outside, each clamping ring all is that two semicircle butt joints form, two and half clamping rings of butt joint are fixed together by screw 8 at joint, can see in the drawings simultaneously, and the inner retaining side of bearing is provided in a side of on the clamping ring.Retainer 5 is equipped with in the outside of rolling element 4, retainer is formed by two semicircle butt joints equally, connect by spring sheet 7 between two and half retainers, shape of spring plate as shown in Figure 3 and Figure 4, being connected as shown in Figure 1 between spring sheet and the retainer, fixedly connected with the end of one and half retainers by screw 10 in two holes of spring sheet, be fixed with two spring pins 9 in the end of second half retainer, other two holes on the spring sheet are inserted on two pins, and two wings of spring sheet perk are inserted in the retainer, like this because the elastic reaction of spring sheet, connection can not get loose, and retainer is equipped with retainer lid 6 outward, and 1 is bearing outer ring among the figure, it also is two semicircles, directly is installed in the bearing support.

As seen from Figure 2, the utility model can also be used for not having the bearing of outer rib, and rib is not with in outer ring 1 as shown in Figure 2.

Claims

1, split bearing, it comprises bearing outer ring, inner ring, rolling element and retainer, it is characterized in that outer ring, inner ring and retainer are two semicircle butt joints and form, inner ring is equipped with clamping ring outward, use bolton between two and half clamping rings, the two halves retainer links to each other with spring sheet, connects with clench nail between spring sheet and the retainer.

2,, it is characterized in that the bearing inner retaining side is located on the clamping ring according to the said split bearing of claim 1.

3, according to the said split bearing of claim 1, it is characterized in that being screwed between spring sheet and one of them half retainer and be connected, and peg graft with pin between second half retainer, spring sheet has two wings simultaneously, is inserted in the retainer.
