Description

Motor front end cover

Technical Field

The utility model relates to the field of motors, in particular to a motor front end cover.

Background

The front end housing of motor is used for connecting motor casing to can fix the motor main shaft, this structure requirement to the rear end housing improves, the structure of current front end housing is more complicated, and the volume is great, and bulk strength is not enough, and especially the terminal surface of end cover is used for supporting the main shaft, and the intensity requirement is than great, and the connection structure of front end housing and casing is also very important, and current connection structure is mostly through making the lateral wall of end cover thick, sets up the connecting hole, and not only extravagant material has increased the volume of end cover moreover.

SUMMERY OF THE UTILITY MODEL

The utility model provides a motor front end cover which is simple and compact in structure, high in overall strength and capable of firmly supporting a motor spindle.

In order to achieve the purpose, the utility model provides the following technical scheme: an electric machine front end cap comprising:

the end cover comprises an end cover shell, wherein the end cover shell is integrally cylindrical and hollow, a shell connecting hole is formed in one end of the end cover shell, an end face is formed in the other end of the end cover shell, a boss is arranged on the outer side face of the end face, a spindle penetrating hole is formed in the center of the end face and is surrounded by a spindle guide seat, a plurality of connecting seats are arranged on the periphery of the outer side wall of the end cover shell, and connecting holes are formed in the connecting seats.

Preferably, the inner side of the end face is provided with a plurality of reinforcing ribs in a scattering shape around the main shaft guide seat, and the reinforcing ribs extend to the inner side wall of the end cover shell.

Preferably, the spaced reinforcing ribs are provided with reinforcing bosses.

Preferably, the boss is square, and end face connecting holes are formed in the vertex angle of the boss.

Preferably, the side wall of the connecting seat is provided with a fastening screw hole.

Compared with the prior art, the utility model has the beneficial effects that:

simple structure is compact, can strengthen the structural strength of end cover casing through setting up the boss and strengthening protruding muscle, satisfies the firm support to motor spindle, adopts overhanging connecting seat moreover, has guaranteed the joint strength of end cover with the casing, also makes the wall thickness of end cover can do thinly.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.

As shown in fig. 1 to 4, the present invention provides a motor front cover, comprising:

end cover casing 1, end cover casing 1 whole be cylindric, its inside fretwork, one end is provided with casing connecting hole 2, the other end is provided with terminal surface 4, terminal surface 4's lateral surface on be provided with a boss 8, boss 8 and terminal surface 4 are integrative aluminium die-casting shaping structure, boss 8 can increase the thickness at terminal surface 4 middle part, simultaneously, terminal surface 4's center be provided with main shaft perforation 9, main shaft perforation 9 enclose by main shaft guide holder 3, main shaft guide holder 3 supports the main shaft with terminal surface 4 of wall thickness thickening simultaneously, can satisfy the operation requirement of motor.

Meanwhile, a plurality of connecting seats 6 are arranged on the periphery of the outer side wall of the end cover shell 1, connecting holes 11 are formed in the connecting seats 6, the connecting seats 6 are located on the outer side of the end cover shell 1 and protrude out of the outer wall of the end cover shell 1, the thickness of the end cover shell 1 is not occupied, and the wall thickness of the side wall of the end cover shell 1 can be reduced.

In order to further improve the strength, a plurality of reinforcing ribs 5 are radially arranged on the inner side of the end face 4 around the main shaft guide seat 3, the reinforcing ribs 5 extend to the inner side wall of the end cover shell 1, the number of the reinforcing ribs 5 is not too small, preferably 6-8, and reinforcing bosses 7 are arranged on the reinforcing ribs 5 at intervals, so that the strength of the end cover shell 1 can be further improved.

The boss 8 is square, end face connecting holes 10 are formed in the top corners of the boss and used for connecting other parts of the end portion of the motor, and the end face connecting holes 10 are formed in the boss 8 and can also guarantee the connecting strength.

In this embodiment, the side wall of the connecting seat 6 is provided with a clinch screw hole 12, and a clinch screw can be installed in the clinch screw hole 12, so as to lock and position the connecting screw in the connecting seat 6, thereby playing a role in preventing looseness.

The motor front end housing simple structure of this application is compact, can strengthen the structural strength of end cover casing through setting up the boss and strengthening protruding muscle, satisfies the firm support to the motor spindle, adopts overhanging connecting seat moreover, has guaranteed the joint strength of end cover with the casing, also makes the wall thickness of end cover can do thinly.

It should be noted that all directional indicators (such as up, down, left, right, front, and back) in the embodiments of the present invention are only used to explain the relative position relationship between the components, the motion situation, and the like in a specific posture (as shown in the drawings), and if the specific posture is changed, the directional indicator is changed accordingly.

In addition, the descriptions related to "first", "second", etc. in the present invention are only for descriptive purposes and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature. In the description of the present invention, "a plurality" means at least two, e.g., two, three, etc., unless explicitly specifically defined otherwise.

In the present invention, unless otherwise expressly stated or limited, the terms "connected," "secured," and the like are to be construed broadly, and for example, "secured" may be a fixed connection, a removable connection, or an integral part; can be mechanically or electrically connected; they may be directly connected or indirectly connected through intervening media, or they may be connected internally or in any other suitable relationship, unless expressly stated otherwise. The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.

In addition, the technical solutions in the embodiments of the present invention may be combined with each other, but it must be based on the realization of those skilled in the art, and when the technical solutions are contradictory or cannot be realized, such a combination of technical solutions should not be considered to exist, and is not within the protection scope of the present invention.
