Description

Motor spindle protection device

Technical Field

The utility model relates to a motor protection field specifically is a motor spindle protection device.

Background

An electric motor is a device that converts electrical energy into mechanical energy. The electromagnetic power generator utilizes an electrified coil (namely a stator winding) to generate a rotating magnetic field and acts on a rotor (such as a squirrel-cage closed aluminum frame) to form magnetoelectric power rotating torque. The motors are divided into direct current motors and alternating current motors according to different power supplies, most of the motors in the power system are alternating current motors, and can be synchronous motors or asynchronous motors (the rotating speed of a stator magnetic field of the motor is different from the rotating speed of a rotor to keep synchronous speed). The motor mainly comprises a stator and a rotor, and the direction of the forced movement of the electrified conducting wire in a magnetic field is related to the current direction and the direction of a magnetic induction line (magnetic field direction). The working principle of the motor is that the magnetic field exerts force on current to rotate the motor.

In the practical and practical process of the motor, the operation environment is complex, the joint of the main shaft of the motor and the shell of the motor is easily corroded by dust and water vapor, meanwhile, the stress direction of the main shaft is complex in the machining process, the deviation is easy to occur, the abrasion is accelerated, and the service life of the motor is shortened.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a motor spindle protection device to solve the problem that proposes among the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme:

a motor spindle protector comprises a sleeve; the sleeve passes through second bolt fixedly connected with collar, and the collar parcel has sealed the pad, and sealed pad extends to the outside for annular seal pad and edge.

As a further aspect of the present invention: the sleeve is of a circular truncated cone-shaped structure.

As a further aspect of the present invention: the sleeve is provided with a through hole penetrating through the sleeve, a bearing sleeve is nested in the through hole, and the sleeve is rotatably sleeved with the spindle through the bearing sleeve.

As a further aspect of the present invention: the mounting ring is fixedly connected with a shell of the motor through a first bolt.

As a further aspect of the present invention: the sealing gasket extends to the gap between the sleeve and the mounting ring and also to the gap between the mounting ring and the motor housing.

As a further aspect of the present invention: and reinforcing plates which are distributed circumferentially are arranged on the outer side of the sleeve.

As a further aspect of the present invention: the reinforcing plate is fixedly connected with the front part of the sleeve through a third bolt, and the reinforcing plate is fixedly connected with the rear part of the sleeve through a second bolt.

Compared with the prior art, the beneficial effects of the utility model are that: the sealing gasket extends outwards to have a good sealing effect on the connection part of the spindle and the motor shell, so that dust and water vapor are prevented from corroding the spindle and the motor; through being equipped with the reinforcing plate that is the circumference and distribute, provide the support of circumference to the main shaft, avoid the vertical force to cause the main shaft skew to wear with higher speed, the crashproof anti-falling characteristic of reinforcing motor prolongs motor life.

In the figure: 1-a sleeve; 2-bearing sleeve; 3-a main shaft; 4-mounting a ring; 5-a sealing gasket; 6-a first bolt; 7-a second bolt; 8-a reinforcing plate; 9-third bolt.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Example 1

Referring to fig. 1-3, in an embodiment of the present invention, a motor spindle protection device includes a sleeve 1; the sleeve 1 is of a circular truncated cone-shaped structure, a through hole penetrating through the sleeve 1 is formed in the sleeve, a bearing sleeve 2 is nested in the through hole, and the sleeve 1 is rotatably sleeved with a spindle 3 through the bearing sleeve 2; the sleeve 1 is fixedly connected with a mounting ring 4 through a second bolt 7, the mounting ring 4 is fixedly connected with a shell of the motor through a first bolt 6, and then the whole device is fixed on the shell of the motor, and the mounting and the dismounting are convenient.

The installation ring 4 parcel has sealed the pad 5, and sealed pad 5 is sealed pad of annular and edge to the outside extension, and sealed pad 5 extends to the clearance between sleeve 1 and the installation ring 4 and also extends to the clearance between installation ring 4 and the motor housing simultaneously, avoids dust or steam and main shaft contact for main shaft and motor housing junction are in better encapsulated situation, the life of extension motor.

Example 2

This example differs from example 1 in that: the sleeve 1 outside is equipped with the reinforcing plate 8 that is the circumference and distributes, and reinforcing plate 8 passes through the anterior fixed connection of third bolt 9 with sleeve 1, and reinforcing plate 8 passes through second bolt 7 and sleeve 1 rear portion fixed connection, and then strengthens sleeve 1's intensity for main shaft 3 all has the support in all directions, and then avoids the main shaft because the effect that receives the vertical force takes place great skew and then accelerated wear.

The following are specifically mentioned: the bearing sleeve in the application is the prior art; the novel point of the application is that the circular truncated cone-shaped sleeve, the mounting ring, the sealing gasket and the reinforcing plate are innovative; the sealing gasket extends outwards to have a good sealing effect on the connection part of the spindle and the motor shell, so that dust and water vapor are prevented from corroding the spindle and the motor; through being equipped with the reinforcing plate that is the circumference and distribute, provide the support of circumference to the main shaft, avoid the vertical force to cause the main shaft skew to wear with higher speed, the crashproof anti-falling characteristic of reinforcing motor prolongs motor life.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
