Abstract
The utility model discloses a fastening structure of a motor end cap, which comprises a front end cap (1), a rear end cap (2), a bolt (3) and a nut (4). The bottom edge of the front end cap (1) protrudes to form an upper protruding lug (11), and the bottom edge of the rear end cap (2) protrudes to form a lower protruding lug (21). The bolt (3) penetrates through through-holes (5) of the upper protruding lug (11) and the lower protruding lug (21) and is connected with the nut (4) so as to lock the front end cap (1) and the rear end cap (2). The upper protruding lug (11) or the lower protruding lug (21) is provided with a plurality of turn edges (6), and the tops of the plurality of turn edges (6) abut against the nut (4) to enable the nut (4) not to rotate. The fastening structure of the motor end cap does not need an elastic washer, thereby simplifying a motor structure, reducing production cost, improving production efficiency and being good in manufacturability.
Description
Technical field:
The utility model relates to a kind of electric motor end cap fastening structure, belongs to machine field.
Background technology:
The installation method of traditional electric motor end cap is with the front and rear cover connection by screw bolt and nut, for preventing when motor moves, nuts and bolt is loosening to break away from because of vibration makes, generally adopt and below nut, install spring washer additional, but this kind scheme production cost height, production efficiency is low, and the pressure that produces in installation process easily explodes spring washer, and manufacturability is poor.
Summary of the invention:
The purpose of this utility model provides a kind of electric motor end cap fastening structure, and it reduces elastic washer, reduces production costs, and enhances productivity good manufacturability.
The purpose of this utility model is achieved by following technical proposals.
A kind of electric motor end cap fastening structure, comprise front end housing, rear end cap, screw bolt and nut, the front end housing bottom margin is protruding with upper lug, the rear end cap bottom margin is protruding with down lug, bolt passes upper lug, down the through hole on the lug and is connected with nut is locked front end housing, rear end cap, upper lug or down lug be provided with some flange, nut is withstood at the top of flange makes the nut can not rotation.
Above-mentioned described some flange quantity are more than one or one.
Above-mentioned described nut is a hex nut, and or several faces of nut are withstood at the flange top.
Above-mentioned described front end housing or rear end cap and lug and flange are one-body molded.。
The utility model compared with prior art, have following effect: 1) upper lug or following lug are provided with some flange, nut is withstood at the top of flange makes the nut can not rotation, reduce elastic washer, product cost is reduced, simplify product structure, enhance productivity, prevent the phenomenon that the pressure that produces is exploded spring washer in installation process, good manufacturability; 2) some flange quantity are more than one or one, and nut is a hex nut, and or several faces of nut are withstood at the flange top, and reasonable in design is simple, make the nut can not rotation.
