As shown in fig. 1, the utility model provides a drum motor, drum motor installs on axle bed 1, and axle bed 1 can be fixed in ground or mechanical equipment's frame, supports and fixes drum motor.
The drum motor includes a fixed shaft 2 and a drum 3.
The roller 3 is sleeved on the fixed shaft 2, and the roller 3 is provided with an inner cavity to accommodate a motor winding arranged on the fixed shaft 2.
The drum 3 is mounted at both ends thereof with a first end cap 31 and a second end cap 32, respectively.
The shaft seat 1 comprises a first shaft seat 11 and a second shaft seat 12.
The first end cover 31 is provided with a shaft hole 4, one end of the fixed shaft 2 extends out of the shaft hole 4 and is fixedly arranged on the first shaft seat 11, so that the first shaft seat 11 supports and fixes the fixed shaft 2, and meanwhile, the first end cover 31 can rotate by taking the fixed shaft 2 as a shaft.
The end surface of the outer side of the second end cover 32 is provided with a rotating shaft 5, and the rotating shaft 5 is rotatably arranged on the second shaft seat 12.
The sleeve 6 is arranged on the end face of the inner side of the second end cover 32, the other end of the fixed shaft 2 extends into the sleeve 6, the fixed shaft 2 is in running fit with the sleeve 6, and the sleeve 6 can rotate by taking the fixed shaft 2 as a shaft.
When the drum motor works, the fixed shaft 2 is stationary, the drum 3 rotates, and the rotating shafts on the first end cover 31, the second end cover 32 and the second end cover 32 rotate along with the drum 3.
The stationary shaft 2 is supported at one end by the first shaft holder 11 and at the other end by the sleeve 6, and the sleeve 6 is supported by the second shaft holder 12 via the second end cap 32 supported by the rotating shaft.
Disc brake and drum brake all can install on the pivot 5 in the second axle bed 12 outside, need not to increase equipment length, have reduced the space and have occupy, make the stopper can not receive the hindrance of fixed axle of immobilization, and the stopper can adopt the less structure of external diameter, has further reduced the space of equipment and has occupy to the stopper installation is convenient with the dismantlement.
Only increased sleeve 6 structure in the 3 inner chambers of cylinder, sleeve 6 can not form the hindrance to motor winding moreover, makes this application drum type motor still can install the motor winding with the same size of current drum type motor, guarantees that the motor performance is the same.
Simultaneously, under the condition that the motor performance is the same, cylinder length is the same, the cylinder motor length of this application can be the same with current cylinder motor's length to make the cylinder motor of this application can directly change the outfit to current band conveyer, have higher compatibility.
In order to ensure the drum-type motor to run stably, the sleeve 6 is arranged coaxially with the rotating shaft 5, and the rotating shaft 5 is arranged coaxially with the fixed shaft 2.
Because pivot 5 and fixed axle 2 are all installed on the axle bed, receive the support of axle bed, sleeve 6, pivot 5 and 2 three of fixed axle are coaxial, make pivot 5 remain throughout coaxial with fixed axle 2, the holistic axis of motor remains stable, thereby make the operation of drum-type motor on the axle bed more steady, avoid causing the motor both ends to beat from top to bottom because pivot 5 and the eccentric settings of fixed axle 2, prevent that the motor from producing the slope relative to the horizontal plane, thereby avoid the belt slope thereupon, the goods scatters and falls out from the belt.
In order to ensure smooth rotation of the components, a first bearing 71 is installed between one end of the fixed shaft 2 and the sleeve 6, a second bearing 72 is installed between the other end of the fixed shaft 2 and the shaft hole 4, and the rotating shaft 5 is installed on a third bearing 73 provided on the second shaft seat 12.
