Description

Technical Field

[0001] This utility model relates to the field of motors, and in particular to output shaft supported motors. Background Technology

[0002] An electric motor is an electromagnetic device that converts or transmits electrical energy based on the law of electromagnetic induction. An electric motor drives external mechanical equipment by rotating its output shaft. However, when a motor uses a long output shaft to drive external equipment, the lack of support in the middle of the output shaft will shorten its lifespan. Utility Model Content

[0003] In order to overcome the shortcomings of existing motors whose output shafts are too long and thus reduce their service life, this utility model provides an output shaft-supported motor.

[0004] The technical solution adopted by this utility model to solve its technical problem is: an output shaft supported motor, including a motor body, a front cover, and an output shaft. The front cover is fixed to the front end of the motor body, and the output shaft is rotatably connected to the motor body. A cylinder is rotatably connected to the front cover, and a sleeve is fixedly connected inside the cylinder. The output shaft passes through the sleeve and is fixedly connected to the sleeve. The motor body is fixed on a base, and a support mechanism for supporting the cylinder is installed on the base.

[0005] According to another embodiment of the present invention, the sleeve is further provided with several support rods evenly distributed on the outer wall, and the top ends of the support rods are fixedly connected to the inner wall of the cylinder.

[0006] According to another embodiment of the present invention, a reinforcing rib is further provided between the support rod and the sleeve.

[0007] According to another embodiment of the present invention, the support rod is further provided with a connecting plate welded to its top end, and the connecting plate is fixedly connected to the inner wall of the cylinder by bolts.

[0008] According to another embodiment of the present invention, a second reinforcing rib is provided between the connecting plate and the support rod.

[0009] According to another embodiment of the present invention, the supporting mechanism is further comprising a horizontal roller conveyor, which is in contact with the outer wall of the cylinder.

[0010] According to another embodiment of the present invention, a ball bearing is further included between the cylinder and the front cover, with the inner ring of the ball bearing fixed on the front cover and the outer ring of the ball bearing fixed on the cylinder.

[0011] According to another embodiment of the present invention, the sleeve is further fixedly connected to the output shaft by screws.

[0012] The beneficial effect of this utility model is that it protects the output shaft with a cylindrical body, and uses a sleeve combined with the cylindrical body and a support mechanism to support the output shaft, thereby avoiding deformation due to excessive length of the output shaft and avoiding affecting its service life.

[0016] Figure 1 This is a schematic diagram of the structure of this utility model.

[0017] As attached Figure 1 As shown, an output shaft supported motor includes a motor body 1, a front cover 2, and an output shaft 3. The front cover 2 is fixed to the front end of the motor body 1, and the output shaft 3 is rotatably connected to the motor body 1. A cylinder 4 is rotatably connected to the front cover 2, and a sleeve 5 is fixedly connected inside the cylinder 4. The output shaft 3 passes through the sleeve 5, and the output shaft 3 and the sleeve 5 are fixedly connected together. The motor body 1 is fixed on a base 6, and a support mechanism 7 for supporting the cylinder 4 is installed on the base 6.

[0018] Several support rods 8 are evenly distributed on the outer wall of the sleeve 5, and the top ends of the support rods 8 are fixedly connected to the inner wall of the cylinder 4. The support rods 8 isolate the sleeve 5 and the cylinder 4 and provide support force.

[0019] A reinforcing rib 9 is provided between the support rod 8 and the sleeve 5. The reinforcing rib 9 can improve the connection strength between the support rod 8 and the sleeve 5.

[0020] A connecting plate 10 is welded to the top of the support rod 8, and the connecting plate 10 is fixedly connected to the inner wall of the cylinder 4 by bolts.

[0021] A reinforcing rib 2 11 is provided between the connecting plate 10 and the support rod 8. The reinforcing rib 2 11 can improve the connection strength between the connecting plate 10 and the support rod 8.

[0022] The support mechanism 7 is a horizontal roller conveyor, which is in close contact with the outer wall of the cylinder 4. When the cylinder 4 rotates, the cylinder 4 will drive the rollers of the horizontal roller conveyor to rotate together through friction. In this way, the horizontal roller conveyor provides support for the cylinder 4 while greatly reducing the resistance of the cylinder 4.

[0023] A ball bearing 12 is connected between the cylinder 4 and the front cover 2. The inner ring of the ball bearing 12 is fixed on the front cover 2, and the outer ring of the ball bearing 12 is fixed on the cylinder 4.

[0024] The sleeve 5 is fixedly connected to the output shaft 3 by screws.

[0025] When the motor body 1 drives the output shaft 3 to rotate, the output shaft 3 will drive the cylinder 4 to rotate synchronously. The cylinder 4, the sleeve 5, and the support mechanism 7 support the output shaft 3 and provide protection for the output shaft 3.
