Motor for oil field drilling

Abstract

The invention relates to a motor for oil field drilling, and the motor comprises a pedestal and a motor main body. One side of the motor main body is provided with a wiring box, and the top of the motor main body is provided with an explosion-proof fan, and the wiring box and the explosion-proof fan are connected to the motor main body through explosion-proof pipes. The motor main body comprises a main shaft, an armature, a stator and a brush carrier. The brush carrier is disposed at one side of the armature, and the motor main body at the top of the brush carrier is provided with a cover plate. The motor main body at one side is provided with an end cover and a pressure plate, and two ends of the main shaft are respectively provided with a first rolling bearing assembly and a second rolling bearing assembly. The first rolling bearing assembly is sealed through a labyrinth bearing sealing structure. The interior of the motor main body also comprises a heater device and a bearing temperature measuring device. After the above structure is employed, the motor is strong in overload capability, is high in reliability, is easy to maintain, and maintains the same size as the size of a motor of the same type in a foreign country. Moreover, the performance index reaches the foreign level, and the motor can completely be used for replacing the motors of the same type in the foreign country, and is worthy of popularization in the whole industry.

Description

technical field

[0001] The invention relates to the field of motors, in particular to a motor used for oil field drilling. Background technique

[0002] The existing oilfield drilling rig platform motors are imported from the United States, while the design, shape and weight of the existing motors of the same power in my country are far from meeting the requirements of oilfield drilling rig platform motors, which makes the domestic motors unable to be used in oil fields. On the drilling rig platform, the motors from the United States must be imported, which is expensive and inconvenient to purchase. Contents of the invention

[0003] The present invention aims to solve the above-mentioned defects, and provides a highly reliable motor for oil field drilling.

[0004] In order to overcome the defects in the background technology, the technical solution adopted by the present invention to solve the technical problems is: a motor for drilling in oil fields, including a base, a...
