152, second bearing end cap 154, sun gear 118, gear lubricant 126, vent valve (the first oil cap 140), cooling insulating oil are (cold
But insulating liquid 124), oil sealing, snorkel 130, gas-liquid separation device 166, external drying device (i.e. water-proof ventilated device
134)。
Specifically, the tooth set 156 in clutch 114 is connect by soket head cap screw with casing 102.Band spline planet carrier
120 rings synchronous with clutch 114 158 are connected by spline engagement.Band spline planet carrier 120 passes through planetary gear 122 and wall wheel
Engagement.First bearing end cap 152 and second bearing end cap 154 are tightly connected with the both ends open of cylinder 148 respectively.First oil cap
140 are removably tightly connected with the first oilhole on casing 102.Cooling insulating oil is injected in the first installation cavity 104, gear profit
Lubricating oil 126 injects in the second installation cavity 106, and gas-liquid separation device 166 is connect by snorkel 130 with external drying device.
Through the above scheme, so that 108 heat of stator winding assembly is detached with gear reduction 110, ensure The gear deceleration
The normal work of structure is not interfered by 108 heat of stator winding assembly, and causes aging, life problems.Simultaneously as stator around
Group component 108 and The gear deceleration structure double-cabin type design, and structure is in individual confined space, and gear reduction 110 can be with
Truly realize the highest liquid lubrication of reliability.Failure risk caused by lubricating oil intrusion motor is solved simultaneously.
In addition, by using oil cooling mode, cooling insulating oil is injected in the first installation cavity 104, is improved existing heat dissipation and is lacked
It falls into, it is rapidly that driving device (such as stator and rotor) temperature lifting is low, while the normal work of the components such as Hall is protected, it is promoted
Electric efficiency and service life.
In conclusion decelerating motor provided by the invention, makes to be not easy mutual shadow between driving device and gear reduction
It rings, that is, is not easy to lead to gear reduction accelerated ageing since motor temperature rise is excessively high, be not easy to occur on gear reduction
Lubricating oil intrusion driving device the case where, improve the stability and reliability of decelerating motor.
