State the end face of shaft end of the axially position plane beyond corresponding power interface.
At least one described power interface has been fixedly and coaxially connected motor.Be equipped with motor the power interface be with
Power interface, the power interface for not installing motor is reserved power interface, and reserved power interface further includes the relatively described arm
The reserved cover 18 that frame is fixedly connected, the axial mask of reserved cover move in the outside of corresponding shaft end to that wouldn't install motor
Power interface, which is given, to be protected.The reserved cover is usually securely attached to the outside of the bearing block or retaining ring.
According to the cloth set direction of each change gear shaft of the multistage spur gear reduction gearing mechanism, with each power interface
The motor of connection is located at mine wall side or mined out side.It, can be with by the connection of more power interfaces of different motor and different location
Different power is transferred to cutting drum via different transmission systems, realizes the power output of different characteristics.
Power interface is more, and the possible power output situation that the cutting mechanism can be provided is also more.Permit in structure
Perhaps in the case where, the application proposes a kind of preferred the case where power interface is arranged as much as possible: far from arm support connecting structure
A power interface is respectively arranged in the two neighboring change gear shaft at place end, and is located at opposite cantilever crane far from planetary gear speed reducing mechanism
Side (i.e. mined out side) shaft end on, while a power interface is respectively arranged in the both ends of other each change gear shafts.
By taking Fig. 1 a as an example, the multistage spur gear reduction gearing mechanism is three-level deceleration mechanism, and there are four change gear shafts
With three idler shafts, according to transmission direction, first stud gear axis, the first idler shaft 31 and second stud gear axis realize first
Grade is slowed down, alternatively referred to as high-speed drive, and second stud gear axis, the second idler shaft 32 and third change gear shaft realize the second level
Slow down, alternatively referred to as middling speed is driven, and third change gear shaft, third idler shaft 33 and the 4th change gear shaft realize that the third level subtracts
Speed, alternatively referred to as low speed rotation.Power interface includes high-speed interface 11, medium speed interfaces 12, low-speed interface 13 and end interface 14.
In order to protrude the correspondence of power interface setting position, the appended drawing reference of the power interface in other accompanying drawings is with reference to corresponding in Fig. 1 a
The appended drawing reference of power interface at position.
With reference to Fig. 1 a-1d, according to interface close to mine wall side or mined out side, high-speed interface, which may include that high speed is mined out, to be flanked
