Abstract

The utility model discloses a kind of specific type of electric machine with spiracle, comprise motor casing, be arranged on the end cap at motor casing two ends, stators and rotators, the end cap of described one end is provided with spiracle, described spiracle is threaded with end cap, and be communicated with inside motor casing, its advantage is: by spiracle body and end cap are arranged to screw connection structure, and spiracle is inverted " L " shape structure, under ensureing that motor casing is in communication with the outside the prerequisite of breathing, can also prevent sand from entering motor casing, guarantee that specific type of electric machine normally uses, in addition on the one hand, in the utility model, spiracle body is threaded with end cap, after spiracle blocking, only need to change spiracle body, without the need to changing whole end cap, reduce the cost of overhaul.

Description

With the specific type of electric machine of spiracle
Technical field
The utility model relates to specific type of electric machine technical field, particularly relates to a kind of specific type of electric machine with spiracle.
Background technology
Field is manufactured at specific type of electric machine, motor-driven end is by inner oil seal, bearing, end cap and bearing cap assemble, because motor is in high speed rotating process, bearing is subject to larger radial load and axial force, so have very high requirement to the lubrication of bearing, motor motor casing inside in running can generate heat, cause motor casing internal temperature and pressure change, when temperature is too high, directly can affect the lubrication of bearing, easily cause lubrication failure, shorten bearing useful life, be consistent under high temperature and low-temperature condition in order to ensure the pressure in motor casing, the end cap of existing specific type of electric machine is provided with spiracle, existing spiracle comprises: the first mutually through hole section and the second hole section, angle between first hole section and the second hole section is acute angle or right angle, although the spiracle of fold-line-shaped can through motor casing, heat in motor casing is shed fast, guarantee that its air pressure inside is communicated with atmospheric pressure, but existing spiracle directly arranges on end cap, after certain life cycle, spiracle easily blocks, cannot repair, this just needs to change end cap, improve maintenance cost.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of specific type of electric machine with spiracle, spiracle body and end cap are arranged to screw connection structure, and spiracle is inverted " L " shape structure, under ensureing that motor casing is in communication with the outside the prerequisite of breathing, can also prevent sand from entering motor casing, guarantee that specific type of electric machine normally uses, in addition on the one hand, in the utility model, spiracle body is threaded with end cap, after spiracle blocking, only needing to change spiracle body, without the need to changing whole end cap, reducing the cost of overhaul.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of specific type of electric machine with spiracle, comprise motor casing, be arranged on end cap, the stators and rotators at motor casing two ends, the end cap of described one end is provided with spiracle, and described spiracle is threaded with end cap and is communicated with inside motor casing.
Described spiracle comprises bolt shape body and is located at inversion " L " the shape through hole in the middle part of bolt shape body.
The screwed hole that described bolt fills on body and end cap is sealed and matched.
The beneficial effect adopting technique scheme to produce is: by spiracle body and end cap are arranged to screw connection structure, and spiracle is inverted " L " shape structure, under ensureing that motor casing is in communication with the outside the prerequisite of breathing, can also prevent sand from entering motor casing, guarantee that specific type of electric machine normally uses, in addition on the one hand, in the utility model, spiracle body is threaded with end cap, after spiracle blocking, only need to change spiracle body, without the need to changing whole end cap, reduce the cost of overhaul.
Accompanying drawing explanation
Fig. 1 is the utility model front view;
Fig. 2 is the A-A cutaway view of Fig. 1;
In the accompanying drawings: 1, end cap; 2, bolt shape body; 3, through hole.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Existing spiracle comprises: the first mutually through hole section and the second hole section, angle between first hole section and the second hole section is acute angle or right angle, although the spiracle of fold-line-shaped can through motor casing, heat in motor casing is shed fast, guarantee that its air pressure inside is communicated with atmospheric pressure, but existing spiracle directly arranges on end cap, after certain life cycle, spiracle easily blocks, cannot repair, this just needs to change end cap, improve maintenance cost, for this reason, the utility model provides a kind of specific type of electric machine with spiracle as shown in Figure 1-2, comprise motor casing, be arranged on the end cap 2 at motor casing two ends, stators and rotators, the end cap 2 of described one end is provided with spiracle, described spiracle is threaded with end cap 2, and be communicated with inside motor casing, inversion " L " the shape through hole 3 that described spiracle comprises bolt shape body 2 and is located in the middle part of bolt shape body 2, the screwed hole that described bolt fills on body and end cap 2 is sealed and matched, it is by being arranged to screw connection structure by spiracle body and end cap, and spiracle is inverted " L " shape structure, under ensureing that motor casing is in communication with the outside the prerequisite of breathing, can also prevent sand from entering motor casing, guarantee that specific type of electric machine normally uses, in addition on the one hand, in the utility model, spiracle body is threaded with end cap, after spiracle blocking, only needs to change spiracle body, without the need to changing whole end cap, reduce the cost of overhaul.
