The utility model discloses a nylon cover of bowl shape of installation on the armature shaft of spline front end department covers in the protruding circle periphery of protection shroud to effectively prevented the lubricating grease that drive assembly transmission position was injected into and produced the phenomenon of splashing and cause the lubricating grease to run off, both protected armature coil not influenced by splashing of lubricating grease, ensured the good lubrication effect of each drive disk assembly again, realized the long-term stable operation of starter.
Description
Technical Field
The utility model relates to a speed reduction starter splashproof formula armature.
Background
The armature shaft of the speed reduction starter generally adopts spline transmission, and the end part of the armature is matched with the needle bearing and is meshed with the planetary gear, so that a certain amount of lubricating grease needs to be filled in the assembly process of the part. When the armature rotates at a high speed, the filled lubricating grease splashes around the inside, so that a plurality of greases can be splashed on the tail part of the armature coil, and the lubricating grease splashed on the armature coil is easy to damage an insulating layer of the coil to reduce the lubricating grease on a meshing part, so that the armature, the bearing and the planetary gear are damaged due to the fact that the lubricating grease cannot be lubricated, and the starter fails to work.
Disclosure of Invention
The to-be-solved technical problem of the utility model is: in order to overcome the deficiency among the prior art, the utility model provides a can effectively prevent that lubricating grease from producing the speed reduction starter splashproof formula armature of phenomenon of splashing.
The utility model provides a technical scheme that its technical problem adopted is: the utility model provides a speed reduction starter splashproof formula armature has armature assembly and armature shaft, and the armature shaft passes through the spline to be connected with armature assembly transmission, and the drive assembly transmission of armature shaft front end portion and starter is connected, drive assembly and armature assembly between be equipped with the protective cover lid, the protective cover lid inboard has the protruding circle towards armature assembly, is located and installs the nylon cover of calathiform on the armature shaft of spline front end portion, the main aspects opening cover of nylon cover is in the protruding circle periphery of protective cover lid.
Specifically speaking, the nylon cover include cylinder portion and bowl shape portion, cylinder portion hole and armature shaft cooperation installation, bowl shape portion hole is greater than the protruding circle periphery.
The utility model has the advantages that: the utility model discloses a nylon cover of bowl shape of installation on the armature shaft of spline front end department covers in the protruding circle periphery of protection shroud to effectively prevented the lubricating grease that drive assembly transmission position was injected into and produced the phenomenon of splashing and cause the lubricating grease to run off, both protected armature coil not influenced by splashing of lubricating grease, ensured the good lubrication effect of each drive disk assembly again, realized the long-term stable operation of starter.
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 structure of the planetary gear set comprises an armature assembly, 2 parts of an armature shaft, 3 parts of a spline, 4 parts of a driving assembly, 5 parts of a protective cover cap, 6 parts of a convex ring, 7 parts of a nylon sleeve, 8 parts of a cylindrical part, 9 parts of a bowl-shaped part, 10 parts of an intermediate cover, 11 parts of an internal gear and 12 parts of a planetary gear assembly.
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 splash-proof armature of the speed reduction starter shown in fig. 1 comprises an armature assembly 1 and an armature shaft 2 which are arranged in a starter shell, wherein the armature shaft 2 is in transmission connection with the armature assembly 1 through a spline 3, the front end part of the armature shaft 2 is in transmission connection with a driving assembly 4 of the starter, specifically, the driving assembly 4 comprises an intermediate cover 10, an internal gear 11 and a planetary gear component 12, the intermediate cover 10 is fixedly connected with the inner wall of a shell of the armature assembly 1, the internal gear 11 is arranged in the intermediate cover 10 and transmits an isolator of the driving assembly 4, a central gear of the planetary gear component 12 is arranged at the front end of the armature shaft 2, and a planetary gear of the planetary gear component 12 is in meshing transmission with the internal gear.
Drive assembly 4 and armature assembly 1 between be equipped with protective cover lid 5, protective cover lid 5 inboard has protruding circle 6 towards armature assembly 1, is located and installs the nylon cover 7 of bowl shape on the armature shaft 2 of 3 front ends of spline, nylon cover 7 include cylinder portion 8 and bowl shape portion 9, 8 holes of cylinder portion and the cooperation installation of armature shaft 2, the 9 holes of bowl shape portion are greater than protruding circle 6 periphery, the bowl shape portion 9 of nylon cover 7 covers in the protruding circle 6 periphery of protective cover lid 5 for form the seal structure of a labyrinth between 9 holes of bowl shape portion and the protruding circle 6 periphery, thereby can prevent that the lubricating grease that splashes from spattering on the armature coil.
The utility model discloses a nylon cover 7 of a bowl shape of installation on armature shaft 2 of 3 front ends departments of spline covers in the 6 peripheries of protruding circle of protective cover lid 5, when the armature rotates at a high speed, can prevent effectively that the lubricating grease that 4 transmission positions of drive assembly injected into from producing the phenomenon of splashing and causing the lubricating grease to run off, has both protected armature coil not receive the influence of splashing of lubricating grease, ensures the good lubrication effect of each drive disk assembly again, realizes the long-term stable operation of starter.
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.
