Abstract

A divided bearing relates to the technical field of mechanics for decreasing friction among rotation axes. The prior plain bearing can not be arranged on a plurality of particular bearings. The utility model divides closed-form bearing rings which are commonly used and ball frames into two or more independent and attachable parts, which can be conveniently arranged on the plain bearings and other particular bearings so as to substitute a bearing shell to reduce friction.

Description

Divided bearing

Be used for mechanical field to reduce the friction between the axis body in relative rotation.

Common being seen bearing all is to be made of the bearing inner race of unitary closed and outer ring and closed ball rack, rolls in the ball grooves of ball between inside and outside circle.This bearing can't be sleeved on the axle of some specific use, thin neck axle as shown in Figure 5 and crankshaft etc. generally all be to prolong its working life with bearing shell between this class is turned, but bearing shell do not have the effect that reduces to rub, the mechanical efficiency loss is very big, and needs often to change.

The related bearing of the utility model can be enclosed within on plain shaft and the most special axle, and all available this bearing replaces bearing shell between the turning of many use bearing shells, and installs also very conveniently, and its benefit is conspicuous.

Solution of the present utility model is that bearing inner race and outer ring are made two or more independently loop respectively, design has the dovetail groove and the dovetail key of interlock mutually on the conjunction plane between each loop, can be the race ring of a sealing with its butt joint, and reinforce by fastening piece dovetail wedge and pin.Ball rack between the inside and outside circle of bearing also be by two or more independently the arc ball rack be connected into the ball bobbin of a sealing by pin key.

Fig. 1,2,3,4 has described an embodiment of the present utility model.Bearing inner race (1) and bearing outer ring (2) are made of two segmental bearing circles independently respectively.On the conjunction plane of two segmental bearing circles, have the dovetail groove (5) and the dovetail groove (6) of interlock mutually, fixedly ball (a 4) axle ball rack (3) also be by two independently the arc ball rack constitute.Pin key (7) is connected into the ball rack of a sealing by pin-and-hole (8) with it.Open a dovetail wedge groove (9) at the top attachment place of the inside and outside circle of bearing, use dovetail wedge (10) two segmental bearing circle coupling part crosswise fixed.And it is fastening with screw (11).Because this bearing coupling part will be subjected to the effect of certain power.So the oblique pin slotted eye (12) that has on the circle body of the coupling part of the inside and outside circle of bearing is further reinforced with pin (13).

Earlier the bearing inner race butt joint is set on the axle when the utility model is installed, again the ball rack butt joint is fixed in the ball grooves of bearing inner race, at last bearing outer ring is docked, and respectively the inside and outside circle of bearing is reinforced with dovetail wedge and pin.According to different purposes, dovetail keyway and two kinds of connecting modes of dovetail wedge groove can use simultaneously, can select also that it is a kind of.This separation principle also can be used for two row ball bearing and needle bearing.

Claims

1, Divided bearing is made of bearing inner race, bearing outer ring and ball rack.It is characterized in that bearing inner race [1] and bearing outer ring [2] all make two or more independently loop respectively, ball rack [3] is made two or more independently arc frames; Each independent sector can be connected into the circle body of a sealing.

2,, it is characterized in that being connected and fixed with following array structure between the segmental bearing circle by the described Divided bearing of claim 1:

Have the dovetail groove (5) and the dovetail groove (6) of interlock mutually on the conjunction plane between a, the segmental bearing circle;

The connection place at B, segmental bearing circle top has dovetail wedge groove (9), uses dovetail wedge (10) with each segmental bearing circle coupling part crosswise fixed, and with screw (11) that it is fastening;

The oblique pin slotted eye (12) that can insert pin (13) that has on the circle body of c, segmental bearing circle connection place.

3,, it is characterized in that connecting by pin-and-hole (8) by pin key (7) between each arc frame of ball rack (3) by the described Divided bearing of claim 1.
