Abstract
The utility model relates to a mounting structure of a motor end cap, which comprises a front end cap, a rear end cap, bolts and nuts, wherein the front end cap and the rear end cap are connected together through the bolts and the nuts. The mounting structure is characterized in that the contact end surfaces of the head parts of the bolts and the front end cap are provided with sawteeth, and the contact end surfaces of the nuts and the rear end cap are provided with sawteeth, and the sawteeth are respectively embedded into the front end cap and the rear end cap. The utility model causes the product cost to be lowered and the product structure to be simplified without gaskets, can not appear the phenomenon that shockproof gaskets can be blown during the mounting, and has good technic; the sawteeth on the end surfaces of the bolts and the nuts are embedded into the front end cap and the rear end cap, even the motor shocks in work, the bolts and the nuts can not be rotated to become flexible, thereby the mounting structure is stable for work.
Description
Technical field:
The present invention relates to motor, particularly the mounting structure of electric motor end cap.
Background technology:
The assembly method of prior motor end cap is with the front and rear cover connection with screw bolt and nut, because the outer surface of existing electric motor end cap is the plane, and bolt is longer, it is loosening that vibration makes the ease of connection of screw bolt and nut during machine operation, in order to address the above problem: generally install shakeproof washer additional, but this scheme makes the manufacturing cost height, and the pressure that produces in installation process often explodes shakeproof washer, and manufacturability is poor.
The utility model content:
The purpose of this utility model is to provide a kind of does not need to use that packing ring, cost are low, the mounting structure of the electric motor end cap of good manufacturability, working stability.
Utility model is achieved through the following technical solutions:
A kind of mounting structure of electric motor end cap, comprise front end housing, rear end cap, screw bolt and nut, front end housing and rear end cap are installed by screw bolt and nut and are coupled together, the contacted end face of the head of bolt and front end housing is provided with sawtooth, the contacted end face of nut and rear end cap is provided with sawtooth, and described sawtooth is embedded into front end housing and rear end cap respectively.
Above-mentioned described sawtooth distributes on end face ringwise.
The scope of described sawtooth number is 3～16.
Described bolt top has groove.
Described sawtooth is high outside and low outside.
The utility model compared with prior art has following advantage: 1) do not need to use packing ring, product cost is reduced, simplify product structure; 2) do not need to use packing ring, can not appear at and explode shakeproof washer phenomenon, good manufacturability in the installation process; 3) sawtooth on the end face of screw bolt and nut is embedded into front end housing and rear end cap, even vibrate during machine operation, screw bolt and nut also can not rotate and produce loosening, working stability.4) sawtooth on the screw bolt and nut end face adopts high outside and low outside design, urgent after, can produce certain pretightning force.Prevent to get loose; 5) in case of necessity, can adopt the way that strengthens screw bolt and nut end face sectional area, increase frictional force, prevent to get loose.

Below in conjunction with accompanying drawing the utility model is described further.
Embodiment:
Extremely shown in Figure 5 as Fig. 1, the utility model comprises front end housing 1, rear end cap 2, bolt 3 and nut 4, front end housing 1 and rear end cap 2 are installed by bolt 3 and nut 4 and are coupled together, the head 8 and the front end housing 1 contacted end face of bolt 3 are provided with sawtooth 5, nut 4 is provided with sawtooth 6 with rear end cap 2 contacted end faces, and described sawtooth 5 and sawtooth 6 are embedded into front end housing 1 and rear end cap 2 respectively.Described sawtooth 5 and sawtooth 6 distribute on end face ringwise.Described sawtooth 5 or sawtooth 6 number ranges are 3～16.Described bolt 3 tops have groove 7.Described sawtooth 6 is high outside and low outside.
During installation, make a end face that nut 4 is provided with sawtooth 6 towards rear end cap 2, firmly swivel bolt 3 constantly dwindles the head 8 of bolt 3 and the distance of nut 4, close up installation together up to front end housing 1 and rear end cap 2, and sawtooth 5 and sawtooth 6 are embedded into front end housing 1 and rear end cap 2 respectively.
Above-described specific embodiment only is preferred embodiment of the present invention, and the equivalent arrangements of doing according to design concept of the present invention all should be thought and be contained by technology of the present invention such as.
