Description

Motor transmission connecting mechanism for gouge machine

Technical Field

The invention relates to a motor transmission connecting mechanism for a kowtow machine.

Background

The existing motor requires that a rotating shaft on a rotor of the motor is directly connected with a working shaft of equipment, but under the general condition, the motor for the kowtow machine can swing when in operation due to space limitation, sometimes the deflection angle is larger than 2 degrees, the working rotating shaft and the rotating shaft of the motor are not concentric and are accompanied by axial play, and thus the service life of the motor can be seriously influenced.

Disclosure of Invention

The invention aims to overcome the defects of the existing products and provides a motor transmission connecting mechanism for a kowtow machine.

In order to achieve the purpose, the invention is realized by the following technical scheme:

the utility model provides a motor drive coupling mechanism for kowtow machine, includes straight keyway, motor shaft, a plurality of arc key, axle sleeve, inlayer sealing washer, outer sealing washer, oil blanket, oil filler point, straight keyway and motor shaft fixed connection, the inboard at motor shaft is installed to the axle sleeve, a plurality of arc key is fixed on the axle sleeve, a plurality of arc key is along the circumference evenly distributed of axle sleeve, inlayer sealing washer overlaps in the outside of motor shaft, outer sealing washer overlaps the outside at inlayer sealing washer, the oil blanket is installed between inlayer sealing washer and motor shaft, the oil filler point is installed in the motor shaft, a plurality of arc key all is linked together with the oil filler point.

Preferably, there are 4 arced keys.

Preferably, the oil seal contains grease.

Preferably, the arc-shaped bond is subjected to a carbonitriding treatment.

Preferably, the sleeve is adapted to cooperate with a working shaft of the device.

The invention has the following beneficial effects: the arc-shaped keys are uniformly distributed along the circumference of the shaft sleeve, so that the motor can be used at any yaw angle of less than 3 degrees; the plurality of arc keys are communicated with the oil injection hole, so that the arc key matching part is conveniently lubricated, and the service life of the arc key is prolonged; the oil seal is arranged between the inner seal ring and the motor rotating shaft, double-layer protection is formed by the inner seal ring and the outer seal ring, the inner layer prevents lubricating oil from seeping out, and the outer layer prevents sand wind and rainwater from entering, so that a good sealing effect can be achieved; the invention can ensure that the motor is not influenced by the swinging and the vibration when the motor is directly connected with the working shaft of the equipment, allows the motor to have axial movement, keeps the running stability of the whole machine, and aims to ensure the service life cycle of the motor and facilitate the installation and the disassembly of the motor; the arc-shaped key is subjected to carbonitriding treatment to improve the wear resistance.

fig. 3 is a cross-sectional view of the arced key, the bushing, the motor shaft, and the grease.

Detailed Description

The technical scheme of the invention is further explained by combining the attached drawings of the specification:

as shown in fig. 1, a motor transmission connecting mechanism 88 for a kowtow machine is arranged in a motor, as shown in fig. 2 and 3, the motor transmission connecting mechanism for the kowtow machine comprises a straight key groove 8, a motor rotating shaft 7, four arc-shaped keys 1, a shaft sleeve 3, an inner layer sealing ring 6, an outer layer sealing ring 4, an oil seal 2 and an oil filling hole 5, wherein the straight key groove 8 is fixedly connected with the motor rotating shaft 7, the shaft sleeve 3 is arranged on the inner side of the motor rotating shaft 7, the four arc-shaped keys 1 are fixed on the shaft sleeve 3, the four arc-shaped keys 1 are uniformly distributed along the circumference of the shaft sleeve 3, the inner layer sealing ring 6 is sleeved on the outer side of the motor rotating shaft 7, the outer layer sealing ring 4 is sleeved on the outer portion of the inner layer sealing ring 6, the oil seal 2 is arranged between the inner layer sealing ring 6 and, the four arc-shaped keys 1 are communicated with the oil injection hole 5. Grease seal 2 contains grease 21. The arc key 1 is subjected to carbonitriding treatment to improve the wear resistance. The sleeve 3 is intended to cooperate with the working shaft of the device.

The working principle is as follows:

as shown in figures 2 and 3, a straight key groove at the center of the rotating shaft 7 of the motor and an arc key arranged on a shaft sleeve matched with the rotating shaft of the equipment form meshing connection, 4 arc keys are uniformly distributed on the circumference, and the motor is allowed to deflect by no more than 3 degrees. Increase on motor shaft 7 and have the oil filler point, conveniently lubricate arc key cooperation department, extension arc key life, oil blanket 2 is installed between inlayer sealing washer 6 and motor shaft 7, and inlayer sealing washer 6 covers in the outside of motor shaft 7, outer sealing washer 4 covers in the outside of inlayer sealing washer 6, and inside and outside double-deck protection that forms, the inlayer prevents that lubricating oil from oozing, and the skin prevents that the sand blown by the wind rainwater from getting into, can play good sealed effect like this. The invention can make the motor and the working shaft of the device directly connected without the influence of the swing and the vibration, and allow the motor to have axial movement, thus keeping the operation of the whole machine stable, and aiming at ensuring the service life cycle of the motor and facilitating the installation and the disassembly of the motor.

It should be noted that the above list is only one specific embodiment of the present invention. It is obvious that the invention is not limited to the above embodiments, but many variations are possible, for example, several arc keys, and in conclusion, all variations that can be derived or suggested by a person skilled in the art from the disclosure of the invention should be considered as the protection scope of the invention.
