Abstract
The utility model provides an asynchronous motor end cover, belongs to the motor technology field and solves a problem of bad stability of the end cover of the asynchronous motor in the prior art. The asynchronous motor end cover comprises a disc-shaped cover body. A cylindrical rotation shaft hole is arranged in a center of the cover body. An edge of the cover body is connected with four bosses radially extruding outside of the edge of the cover body. Fixed holes are mounted in the bosses. A plurality of reinforcement ribs are radially fixed on a cover surface of the cover body. An amount of the bosses is provided with four. Two bosses disposed one side of the edge of the cover body are integrated. The asynchronous motor end cover has an advantage of good stability.
Description
Technical field
The utility model belongs to technical field of motors, has related to a kind of asynchronous motor, has especially related to a kind of end cap of asynchronous motor.
Background technology
Along with progress and the expanding economy in epoch, motor as the motive use field more and more widely, asynchronous motor be most widely used in all kinds of motor, that requirement is maximum is a kind of.In China, the power consumption of asynchronous motor accounts for more than 60% of total load, generally is applied on the large industry equipment, and the high power epistasis of power can be stablized and obtained generally assert, for huge contribution has been made in economic development.
In asynchronous motor, the general end cap of motor of using is as the capping of motor field frame both sides, thereby the steadiness of End cover for motor had higher requirement, and the intensity of the steadiness of End cover for motor and end cap itself and end cap and the housing fastness fixedly the time is relevant, but the steadiness of the end cap that uses of motor does not reach required requirement at present.
Summary of the invention
There are the problems referred to above in the utility model at existing technology, has proposed the end cap of the good asynchronous motor of a kind of steadiness.
The utility model is realized by following technical proposal: a kind of end cap of asynchronous motor, comprise discoid lid, described lid middle part has the shaft hole that is column, it is characterized in that, described lid edge is connected with the boss that radially protrudes from this lid edge, have fixing hole on the described boss, some reinforcements are radially fixedly arranged on the capping of described lid.
In the end cap of above-mentioned a kind of asynchronous motor, the quantity of described boss is four, and two boss that wherein are positioned at lid edge one side are connected as a single entity.
In the end cap of above-mentioned a kind of asynchronous motor, the quantity of described reinforcement is three, and radial equipartition is in top surface.
Compared with prior art, the end cap of this asynchronous motor strengthens the fastness that lid is installed by boss is set at the lid edge; By the intensity that reinforcement strengthens lid is set at lid; Therefore, this end cap has the good advantage of steadiness.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Among the figure, 1, lid; 2, boss; 3, fixing hole; 4, reinforcement; 5, shaft hole.
Embodiment
Below be specific embodiment of the utility model, and by reference to the accompanying drawings the technical solution of the utility model be further described, but the utility model is not limited to these embodiment.
The end cap of a kind of asynchronous motor as shown in Figure 1, comprise discoid lid 1, described lid 1 middle part has the shaft hole 5 that is column, the edge of described lid 1 is connected with the boss 2 that radially protrudes from this lid 1 edge, have fixing hole 3 on the described boss 2, some reinforcements 4 are radially fixedly arranged on the capping of described lid 1.
In the present embodiment, the quantity of boss 2 is four, and two boss 2 that wherein are positioned at lid 1 edge one side are connected as a single entity.The quantity of reinforcement 4 is three, and radial equipartition is in lid 1 surface.The end cap of this asynchronous motor strengthens the fastness that lid 1 is installed by boss 2 is set at lid 1 edge; By at lid 1 intensity that reinforcement 4 strengthens lid 1 being set; Therefore, this end cap has the good advantage of steadiness.
Specific embodiment described herein only is that the utility model spirit is illustrated.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
Although this paper has used terms such as lid 1, boss 2, fixing hole 3, reinforcement 4, shaft hole 5 morely, do not get rid of the possibility of using other term.Using these terms only is in order to describe and explain essence of the present utility model more easily; They are construed to any additional restriction all is contrary with the utility model spirit.
