Abstract
The utility model discloses a novel dust collar on the inner side of a bearing. The dust collar comprises two semicircular collar bodies which are fixedly connected through a bolt to form a circular body; the bolt is orderly sleeved at the side connecting part of the lower semicircular collar body, the side connecting part of the upper semicircular collar body, a flat washer and a butterfly-shaped washer from bottom to top; the top of the bolt is screwed with a nut, the nut presses against the butterfly-shaped washer, the butterfly-shaped washer presses against the flat washer, the flat washer presses against the side connecting part of the upper semicircular collar body, and the side connecting part of the lower semicircular collar body is clamped between the side connecting part of the upper semicircular collar body and the head part of the bolt. Through the fixing of the bolt and the nut and the locking of the butterfly-shaped washer, the two semicircular collar bodies cannot fall off, the replacement of the bolt and the nut is convenient, and thus the mounting and dismounting of the dust collar are convenient.
Description
Technical field:
The utility model relates to technical field of bearings, more specifically to a kind of dust ring that is installed on the bearing inboard.
Background technique:
Sliding bearing is very extensive in the application of all trades and professions, along with the continuous expansion of sliding bearing application and the continuous progress of technology.
Yet, the existing dust ring that is installed on the sliding bearing inboard generally is all-in-one-piece or split type, the dust ring of split type is that the ring body 1a of two semi-annular shapes forms, as shown in Figure 1, the middle part moulding breach 2a of the left and right sides of one of them semi-circular ring 1a, breach 2a bottom surface is joint 3a, and on two end faces of the left and right sides of another semi-circular ring 1a, form screw 4a, bolt 5a is in breach 2a, the bar section sleeve of bolt 5a is in joint 3a and be screwed onto on two end faces of the left and right sides of another semi-circular ring 1a, when dust ring process being dismounted for multiple times, can destroy the screw thread on dust ring, it is inadequate tight power when bolt 5a is installed, cause dust ring to come off, when this makes the dust ring effect descend, also can make bearing damage.
The model utility content:
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of novel bearing inboard dust ring, and it is fixed by screw bolt and nut, by butterfly gasket, have locking effect, guarantee that two semicircular ring ring bodies can not come off, screw bolt and nut is changed convenient, simultaneously, its easy installation and removal.
The scheme that the utility model solve the technical problem is:
The inboard dust ring of a kind of novel bearing, comprise two semi-annular shape ring bodies, and two semi-annular shape ring bodies are bolted to connection and form circular body together; Described bolt by under from upper sleeve successively below the semi-annular shape ring body the side joint, above side joint, plain washer and the butterfly gasket of semi-annular shape ring body, the top of bolt is bolted with nut, nut is pressed against on butterfly gasket, butterfly gasket is pressed against on plain washer, on the side joint of the semi-annular shape ring body above plain washer is pressed against, between the side joint of the semi-annular shape ring body above the side joint of the semi-annular shape ring body of below is clamped in and the head of bolt.
The left side of described semi-annular shape ring body and the middle part on right side form breach, the bottom surface of breach is joint, the head of bolt below the breach of semi-annular shape ring body in, in the breach of the top of bolt, nut, plain washer and butterfly gasket semi-annular shape ring body up.
The left side of described semi-annular shape ring body and the middle part on right side form the breach of vertical direction.
Outstanding effect of the present utility model is:
Compared with prior art, it is fixed by screw bolt and nut, has locking effect by butterfly gasket, guarantees that two semicircular ring ring bodies can not come off, and screw bolt and nut is changed convenient, simultaneously, and its easy installation and removal.
The accompanying drawing explanation:
Fig. 1 is the structural representation of existing dust ring;
Fig. 2 is structural representation of the present utility model;
Fig. 3 is the structural representation of semi-annular shape ring body of the present utility model.
Embodiment:
Embodiment, be shown in Fig. 2 and shown in Figure 3, and the inboard dust ring of a kind of novel bearing comprises that 1, two semi-annular shape ring body 1 of two semi-annular shape ring bodies is fixed together and forms circular body by bolt 2; Described bolt 2 by under from upper sleeve successively below semi-annular shape ring body 1 side joint 11, above side joint 11, plain washer 3 and the butterfly gasket 4 of semi-annular shape ring body 1, the top of bolt 2 is bolted with nut 5, nut 5 is pressed against on butterfly gasket 4, butterfly gasket 4 is pressed against on plain washer 3, on the side joint 11 of the semi-annular shape ring body 1 above plain washer 3 is pressed against, between the side joint 11 of the semi-annular shape ring body 1 above the side joint 11 of the semi-annular shape ring body 1 of below is clamped in and the head of bolt 2.
The left side of described semi-annular shape ring body 1 and the middle part on right side form breach 6, the bottom surface of breach 6 is joint 11, the head of bolt 2 below the breach 6 of semi-annular shape ring body 1 in, in the breach 6 of the top of bolt 2, nut 5, plain washer 3 and butterfly gasket 4 semi-annular shape ring body 1 up.
The left side of described semi-annular shape ring body 1 and the middle part on right side form the breach 6 of vertical direction.
Working principle: by the bar section by two bolts 2 respectively by under from upper sleeve successively below the through hole of joint 11 of side of the left and right sides of semi-annular shape ring body 1, the through hole of the joint 11 of the semi-annular shape ring body 1 of top, plain washer 3 and butterfly gasket 4, the bar section top of bolt 2 is bolted with nut 5, nut 5 is pressed against on butterfly gasket 4, butterfly gasket 4 is pressed against on plain washer 3, on the side joint 11 of the semi-annular shape ring body 1 above plain washer 3 is pressed against, between the side joint 11 of the semi-annular shape ring body 1 above the side joint 11 of the semi-annular shape ring body 1 of below is clamped in and the head of bolt 2, wherein butterfly gasket 4 has good locking effect, make, bolt 2 and nut 5 can not become flexible and separately make two semi-annular shape ring bodies 1 separately, two semi-annular shape ring bodies 1 are put together on to the circular body formed together to be installed on axle, and be installed in the sliding bearing inboard to guarantee its sealing by interference fit, simultaneously, only need to be after the bearing inboard, separating during its dismounting, after being turned on, bolt 2 and nut 5 just can dismantle, very convenient.
