Shaanxi WGT type connecting middle sleeve drum gear coupling

The WGT-type intermediate sleeve drum gear coupling is composed of an inner gear ring with the same number of teeth and a flange half coupling with external teeth.The external teeth are divided into straight teeth and drum teeth. The so-called drum teeth means that the external teeth are made into a spherical surface. The center of the spherical surface is on the gear axis. The tooth side clearance is larger than that of ordinary gears. The drum-shaped gear coupling can Allows a larger angular displacement (compared to the straight tooth coupling), which can improve the contact conditions of the teeth, increase the torque transmission capacity, and prolong the service life.The contact state along the tooth width when there is angular displacement.

The lubrication method of the WGT-type intermediate sleeve drum gear coupling is generally lubrication. Lubricating oil is sprayed into the small holes at the bottom of the gear teeth, and the oil enters the meshing surface under the action of centrifugal force, which plays a role of lubrication and cooling.The oil flows out from both sides of the tooth after passing through the meshing surface.With this type of lubrication of the drum gear coupling, the oil circulates continuously, the magazine flows out, and the pressure caused by the injected lubricating oil under the action of centrifugal force enters the gear tooth meshing surface, so it has a better lubrication and cooling effect. , Suitable for high-speed and heavy-duty occasions.

WGT type is connected to the intermediate sleeve drum gear coupling with oil storage type. The lubricating oil is injected from the nozzle, and the lubricating oil layer is maintained on the outer circle of the gear due to the centrifugal force of the lubricating oil during rotation.This kind of lubrication method will leave the magazine in the ring gear, and the oil flow has a poor heat dissipation effect, so it is only suitable for occasions with low power and low speed.There is also a non-flowing oil storage lubrication method belonging to this type, which is to pour grease into the inside and seal it, and wash it regularly.The self-flow lubrication of the drum gear coupling, the lubricating oil is injected from the nozzle, flows through the gear backlash, and flows out from the small hole of the sleeve. This lubrication method mainly plays a cooling role, and it is difficult to form an oil film. The wear is faster than the lubrication described below.

WGT type intermediate sleeve drum gear coupling is composed of two halves, which are respectively connected with the driving shaft and the driven shaft.Since the position of the magnetic center of the motor is not marked, the rotor position of the motor is not at the position of the magnetic center when the motor is statically installed, and the influence of the magnetic center of the motor is ignored during the installation process.When the motor rotates, due toDrum gear couplingFor the traction function, the motor rotor cannot be positioned under the magnetic center, which intensifies the impact on the gear coupling and accelerates the damage of the gear shaft.The motor of the same model is still used, supported by sliding bearings, and the axial movement of the rotor is strictly controlled within ±2.5mm of the magnetic center of the motor, and the position of the magnetic center is marked.Mark the stator and rotor.
