Motor transmission connection mechanism for beam-pumping unit

Abstract

The invention discloses a motor transmission connection mechanism for a beam-pumping unit. The motor transmission connection mechanism for the beam-pumping unit comprising a straight key groove, a motor rotating shaft, a plurality of arc keys, a shaft sleeve, an inner layer seal ring, an outer layer seal ring, an oil seal and an oil injection hole; a straight key groove is fixedly connected with the motor rotating shaft; the shaft sleeve is installed on the inner side of the motor rotating shaft; the multiple arc keys are fixed on the shaft sleeve; the inner layer seal ring is sleeved outsidethe motor rotating shaft; the outer layer seal ring is sleeved outside of the inner layer seal ring; the oil seal is installed between the inner layer seal ring and the motor rotating shaft; and the oil injection hole is installed on the motor rotating shaft. The mechanism can allow a motor to be used at any deflection angle of no more than 3 degrees; the multiple arc keys communicate with the oilinjection hole, the lubrication of arc keys matching part is facilitated, and the lives of the arc keys are prolonged; the good seal effect is achieved; not only the service life of the motor is guaranteed, but also the installation and disassembly of the motor is facilitated; and carburized and nitrided treatment is carried out on the arc keys are to increase the wear resistance of the arc keys.

Description

technical field [0001] The invention relates to a motor transmission connection mechanism for a kowtow machine. Background technique [0002] Existing motors require that the rotating shaft on the rotor be directly connected to the working shaft of the equipment, but in general, due to space constraints, the motor for the kowtow machine will oscillate during operation, and sometimes the deflection angle is greater than 2°, and the working shaft and The rotating shaft of the motor is not concentric and accompanied by axial movement, which will seriously affect the service life of the motor. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the existing products and provide a motor transmission connection mechanism for a kowtow machine. [0004] In order to achieve the above object, the present invention is achieved through the following technical solutions: [0005] A motor drive connection mechanism for a kowtow ma...
