Description
Technical Field
The utility model relates to a field of oil-cooled motor, concretely relates to aircraft nose axle extension and motor body coupling's seal structure.
Background
In the prior art, the oil-cooled motor is fixedly connected by sleeving a main shaft and a rotor iron core into a machine head. Because the bearing in the engine head can not form complete sealing performance under high-pressure connection, when the oil inlet and outlet hole stops working suddenly, high pressure is formed, and engine head oil is easy to spray out to the bearing. Resulting in a decrease in the performance of the motor and a reduction in the service life of the motor. The reason for this is that the main shaft of the motor is not sealed with the machine head shaft, which results in oil injection at the bearing of the machine head.
The connection structure form of the oil-cooled motor and the machine head shaft in the prior art and the problems exist:
1. the oil-cooled motor is a common cooling mode, is stable when an oil duct runs at high pressure, and can cause oil overflow at the bearing position when the motor is abnormally stopped and a bearing chamber is subjected to pressure impact.
2. This reduces the efficiency and life of the oil cooling cycle, while increasing the risk of poor sealing.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome the not enough of prior art existence, and provide a aircraft nose axle extension and motor body coupling's seal structure, effectively solve the easy oil leak of oil-cooled motor, the poor problem of leakproofness.
The purpose of the utility model is accomplished through following technical scheme: the sealing structure integrally connected with the motor through the lengthened machine head shaft comprises a main shaft of the connecting machine head, a rear cover, a machine shell and the machine head, wherein a bearing is sleeved at the shaft end of the main shaft of the connecting machine head, is embedded into the rear cover to fix the main shaft of the connecting machine head and the rear cover, and is connected and sealed with the machine shell in a positioning way through a positioning stud; the main shaft of the connecting machine head is provided with a rotor core through a rotor shaft sleeve, a stator core is sleeved outside the rotor core and is arranged in a machine shell, the machine shell and the end surface of the machine head are fixed through screws, and the output end of the main shaft of the connecting machine head is connected and sealed with the machine head through a machine head seal; and the upper end and the lower end of the shell are respectively provided with an oil inlet hole and an oil outlet hole.
As a further technical scheme, the oil inlet hole and the oil outlet hole are connected with the oil inlet and outlet hole of the machine head.
As a preferred technical scheme, the shell is filled with glue through a glue filling process, and the connecting end face of the rear cover and the shell is coated with a sealant.
The utility model has the advantages that: the universality of the oil-cooled motor is realized, the implementation of the disassembly and maintenance of a motor bearing is facilitated, and the precision of the machine head spindle in the production process is ensured; the motor shell is filled with glue, so that the temperature rise is reduced; the sealing device has the advantages of good practicability, excellent sealing property, stable and reliable structure and low cost.
