The utility model discloses set up in the mounting hole of protecgulum body and separate the boss, at the mounting hole installation bush of separating the boss rear side, with jackshaft cooperation and lubricated rotatory position, separate the interior crimping shield of mounting hole of boss front side, surround jackshaft spindle nose tip completely, prevent effectively that foreign matters such as greasy dirt, dust, piece from getting into inside the bush, ensured the operation of starter stable.
Description
Technical Field
The utility model belongs to the technical field of the starter technique and specifically relates to a starter protecgulum seal structure.
Background
The front cover of the starter and the shaft head of the intermediate shaft are easy to wear to generate a gap after long-term use, and external dirt fragments are easy to enter the inside of the front cover due to poor use environment of the starter, so that the intermediate shaft is unsmooth to rotate and the starter cannot be started, and the development trend of the starter is a full-sealing structure except for a driving gear. The matching part of the existing starter front cover and the intermediate shaft is a through hole, the head of the intermediate shaft is supported in a bushing hole in the front cover hole, so that the shaft head and the shaft hole of the intermediate shaft are lubricated through a bushing, the bushing is easy to wear after long-term use, and oil, dust, fragments and the like enter to cause the rotation of the intermediate shaft to generate clamping stagnation.
Disclosure of Invention
The to-be-solved technical problem of the utility model is: in order to overcome not enough among the prior art, the utility model provides a starter protecgulum seal structure to improve the sealed effect of starter protecgulum, prevent effectively that foreign matters such as greasy dirt, dust, piece from getting into inside the bush.
The utility model provides a technical scheme that its technical problem adopted is: the utility model provides a starter protecgulum seal structure, includes the protecgulum body, this internal drive assembly of installing of protecgulum, drive assembly have the jackshaft and rotate and establish the isolator on the jackshaft, protecgulum body front end the mounting hole has, be equipped with in the mounting hole and separate the boss, separate and install the bush in the mounting hole of boss rear side, the spindle nose of jackshaft rotates to be supported in the bush, and the crimping has the shield of sealing jackshaft spindle nose tip in the mounting hole of separation boss front side.
The separating boss is positioned at the front end part of the mounting hole, the front end surface of the bushing is pressed against the side surface of the separating boss, and the front end of the shaft head of the intermediate shaft extends to the side of the dust cover through the inner hole of the separating boss.
The dustproof cover is of an outward convex structure, and two ends of the dustproof cover are inwards folded and fixedly connected with the inner wall of the mounting hole through punching rivets.
The beneficial effects of the utility model are that: the utility model discloses set up in the mounting hole of protecgulum body and separate the boss, at the mounting hole installation bush of separating the boss rear side, with jackshaft cooperation and lubricated rotatory position, separate the interior crimping shield of mounting hole of boss front side, surround jackshaft spindle nose tip completely, prevent effectively that foreign matters such as greasy dirt, dust, piece from getting into inside the bush, ensured the operation of starter stable.
Drawings
The present invention will be further described with reference to the accompanying drawings and embodiments.
Fig. 1 is a schematic structural diagram of the present invention.
In the figure: 1. the novel anti-dust cover comprises a front cover body, 2 parts of a driving assembly, 3 parts of an intermediate shaft, 4 parts of an isolator, 5 parts of a mounting hole, 6 parts of a separation boss, 7 parts of a shaft bushing and 8 parts of a dust cover.
Detailed Description
The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic drawings and illustrate the basic structure of the present invention only in a schematic manner, and thus show only the components related to the present invention.
The sealing structure of the front cover of the starter shown in fig. 1 comprises a front cover body 1, wherein a driving assembly 2 is installed in the front cover body 1, and the driving assembly 2 is provided with an intermediate shaft 3 and a one-way clutch 4 rotatably arranged on the intermediate shaft 3.
The front cover comprises a front cover body 1 and is characterized in that a mounting hole 5 is formed in the front end of the front cover body 1, a separation boss 6 of an integrated structure is arranged at the front end part in the mounting hole 5, a shaft bushing 7 is mounted in the mounting hole 5 at the rear side of the separation boss 6, a shaft head of an intermediate shaft 3 is rotatably supported in the shaft bushing 7, and the front end face of the shaft bushing 7 is pressed against the side face of the separation boss 6.
Separate 6 front sides of boss 5 internal pressure joint have shield 8, the spindle nose front end of jackshaft 3 extends shield 8 side through the hole of separating boss 6, shield 8 be outer convex structure, 8 both ends infolding of shield are through punching rivet and 5 inner wall rigid couplings of mounting hole.
The utility model discloses set up in mounting hole 5 of protecgulum body 1 and separate boss 6, install bushing 7 in the mounting hole 5 of separating 6 rear sides of boss, cooperate and lubricated rotatory position with jackshaft 3, separate 5 internal crimping shield 8 of mounting hole of 6 front sides of boss, surround jackshaft 3 spindle nose tip completely, prevent effectively that foreign matters such as greasy dirt, dust, piece from getting into inside bushing 7.
In light of the foregoing, it will be apparent to those skilled in the art from this disclosure that various changes and modifications can be made without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
