Embodiment Construction

[0013] A vertical AC asynchronous top drive motor, including a stator assembly 11 and its upper end cover 9 and lower end cover 16 installed at both ends, and a rotor assembly 12 in the middle of the stator assembly 11. The rotating shaft 20 of the rotor assembly 12 passes through the non-drive end bearing 8 respectively. Cooperate with the transmission end bearing 15 and the upper end cover 9 and the lower end cover 16, the shaft end of the non-transmission end of the rotating shaft 20 stretches out the upper end cover 9 and the four-point contact ball bearing 5 is also sleeved on the non-transmission end of the rotating shaft 20.

[0014] The specific installation structure of the four-point contact ball bearing 5 is that the upper end cover 9 is fixed with a bearing housing 6, the four-point contact ball bearing 5 is located in the bearing housing 6, and the bearing housing 6 is provided with a bearing that is pressed on the four-point contact ball bearing 5. The front outer...

Abstract

The invention relates to an asynchronous motor, in particular to a vertical AC asynchronous top drive motor. The problem that the domestic top drive motor cannot be manufactured in the prior art is solved. Including the stator assembly, the upper end cover and the lower end cover installed at both ends, and the rotor assembly in the middle of the stator assembly. The rotating shaft of the rotor assembly is matched with the upper end cover and the lower end cover through the non-drive end bearing and the drive end bearing respectively. The shaft end of the non-drive end of the rotating shaft is The upper end cover is stretched out and a four-point contact ball bearing is also sleeved on the non-drive end of the rotating shaft. The vertical AC asynchronous top drive motor of the present invention has a novel and reasonable structural design, strong overload capacity, wide constant power area, low failure rate, safe and reliable use, and fully meets the use requirements of the top drive device for oilfield mining machinery. Ended the history of my country's top drive motors relying on imports.

Description

technical field [0001] The invention relates to an asynchronous motor, in particular to a vertical AC asynchronous top drive motor. Background technique [0002] The oil drilling top drive device is a new device that replaces the traditional rotary table of the drilling rig by driving the drilling tool from the upper part of the motor. It has the advantages of flexible starting up and down, safe and convenient operation, and high production efficiency. It is one of the three major technical equipments for drilling in the 21st century, representing the highest level of drilling technology and mechanical-electrical-hydraulic integrated petroleum equipment. Due to the high technological content of the product and the difficulty in manufacturing, it has been monopolized by foreign countries for a long time. In recent years, with the implementation of the strategy of going global in my country's petroleum industry, a large number of drilling crews have participated in the biddin...
