Abstract
Description
Technical Field
[0001] The utility model provides a synchronous motor and a synchronous groove rolling device at both ends of a pipeline, which is mainly used for cold extrusion groove rolling of pipelines (steel pipes) and belongs to the field of hardware and electromechanical. Background Art
[0002] At present, in the process of laying pipelines (steel pipes), many two steel pipes are connected by clamps. The clamp connection requires grooves at both ends of the steel pipe. The existing technology can only groove one end of the steel pipe first, and then groove the other end of the steel pipe. There is no way to use two groove rolling machines to groove both ends of the steel pipe at the same time. The reason is that the driving mechanisms (motors) of the two groove rolling machines cannot achieve synchronization (consistent speed). Once the speeds of the two driving mechanisms are inconsistent, torque will be generated, which will damage the steel pipe. In practice, choosing a servo motor or a synchronous motor as the driving mechanism of the groove rolling machine in order to achieve synchronization of the two driving mechanisms is not only costly, but also impossible to achieve synchronous groove rolling. How to achieve synchronous groove rolling at both ends of the pipeline is a difficult problem that needs to be solved urgently in the industry. Utility Model Content
[0003] The utility model aims to provide a synchronous motor and a synchronous groove rolling device at both ends of a pipeline. The synchronous motor provided with a one-way bearing solves the problem that the drive at both ends of the pipeline is not synchronized, resulting in torque, damage to the pipeline, and failure to synchronously roll grooves at both ends of the pipeline.
[0004] To achieve the above purpose, the technical solution of the utility model is:
[0005] A synchronous motor comprises a motor and a power output assembly driven by a motor shaft; the power output assembly comprises a one-way bearing, a transmission component and an output component; the motor shaft drives the one-way bearing, the one-way bearing drives the transmission component, and the transmission component drives the output component.
[0006] The outer ring of the one-way bearing is set as a primary gear, and the inner ring of the one-way bearing is connected to a secondary pinion; the transmission component is set as a transmission gear, and the transmission gear includes a coaxial secondary large gear and a third-stage small gear; the output component is set as an output gear, and the output gear includes a third-stage large gear and an output shaft.
[0007] The motor shaft is provided with a gear driving part, the gear driving part is meshed with the first-stage gear, the second-stage small gear is meshed with the second-stage large gear, and the third-stage small gear is meshed with the third-stage large gear.
[0008] A component box is provided, and the power output component is provided in the component box.
[0009] A synchronous grooving device at both ends of a pipeline comprises two grooving heads arranged opposite to each other on a base and two synchronous motors as described above for driving the grooving heads; the grooving heads comprise a main shaft, a pressure wheel driven by a pressure wheel lifting mechanism and a roller connected to the main shaft, and the main shaft of the grooving head is connected to the output shaft of the synchronous motor.
[0010] The groove rolling head and the synchronous motor are fixedly arranged on a base plate, and the base plate is slidably connected with the pedestal.
[0011] The advantages of the utility model are: 1. By utilizing the characteristic that a one-way bearing can rotate freely in one direction and is locked in another direction, a one-way bearing is arranged in the power output assembly of the synchronous motor. When the synchronous motor is used in the process of pipe grooving, when the speed of one end is large, the other end will be driven to rotate together, and no torque is generated at both ends of the pipe, and the pipe will not be damaged; 2. The synchronous motor including the one-way bearing is used to replace the driving motor of the existing grooving machine, which is low in cost and high in efficiency; 3. The synchronous motor including the one-way bearing is used without changing the structure of the original grooving machine, so it has good applicability, low transformation cost, and is conducive to promotion.

DETAILED DESCRIPTION
[0017] The utility model is further described below in conjunction with the accompanying drawings. The accompanying drawings are only used for exemplary description and cannot be understood as limiting the present patent.
[0018] In order to more concisely describe the present embodiment, some parts known to those skilled in the art but not related to the main content of the present invention are omitted in the drawings or descriptions. In addition, for the convenience of description, some parts in the drawings are omitted, enlarged or reduced, but they do not represent the size or entire structure of the actual product.
[0019] The utility model relates to a synchronous motor, such as Figure 1 , Figure 2 As shown, it includes a power output assembly driven by a motor 1 and a motor shaft 11; the power output assembly includes a one-way bearing 2, a transmission component and an output component; the motor shaft 11 drives the one-way bearing 2, the one-way bearing 2 drives the transmission component, and the transmission component drives the output component.
[0020] The one-way bearing 2 is also called an overrunning clutch, which is characterized in that it can rotate freely in one direction and will be locked in the non-rotating direction.
[0021] Preferably, if Figure 2 As shown, the transmission component is set as a transmission gear 3, the output component is set as an output gear 4, and the components of the power output assembly are driven by gears. The outer ring of the one-way bearing 2 is provided with a primary gear 21, and the inner ring of the one-way bearing 2 is provided with a secondary pinion 22; the transmission gear 3 includes a coaxial secondary large gear 31 and a third-stage small gear 32; the output gear 4 includes a third-stage large gear 41 and an output shaft 42.
[0022] The motor shaft 11 is provided with a gear driving part 12, which meshes with the primary gear 21, driving the outer ring of the one-way bearing 2 to rotate, thereby driving the secondary pinion 22 of the inner ring of the one-way bearing 2 to rotate; the secondary pinion 22 meshes with the secondary large gear 31, and drives the secondary large gear 31 and the tertiary pinion 32 coaxially arranged on the transmission gear 3 to rotate together; the tertiary pinion 32 meshes with the tertiary large gear 41, driving the output gear 4 to rotate, thereby outputting the power of the motor through the output shaft 42.
[0023] Preferably, a component box 5 is provided, and the power output component is arranged in the component box 5 .
[0024] A synchronous groove rolling device at both ends of a pipeline, such as Figure 3 , Figure 4 As shown, it includes two groove rolling heads 6 arranged opposite to each other on the base 7 and two synchronous motors as mentioned above for driving the groove rolling heads 6; the groove rolling head 6 includes a main shaft 61, a pressure wheel 63 driven by a pressure wheel lifting mechanism 62, and a roller 64 connected to the main shaft 61, and the main shaft 61 of the groove rolling head is connected to the output shaft 42 of the synchronous motor.
[0025] Furthermore, the groove rolling heads 6 and the synchronous motor are fixedly arranged on the base plate 8 , and the base plate 8 is slidably connected to the base 7 , so that the distance between the two groove rolling heads 6 can be adjusted according to the length of the pipeline 9 .
[0026] The groove rolling heads 6 at both ends of the pipe 9 are driven by synchronous motors equipped with one-way bearings 2, so that grooves can be rolled at both ends of the pipe 9 at the same time. The pipe 9 will not generate torque due to the inconsistent rotation speeds of the synchronous motors at both ends, and the end with a faster rotation speed will drive the other end to rotate. During the groove rolling process, the two ends of the pipe 9 have a characteristic that if one end rotates faster, the other end will rotate accordingly, that is, whichever one rotates faster will follow the other. No torque will be generated at both ends of the pipe 9, and the pipe 9 will not be twisted or damaged.
[0027] The emergence of the synchronous motor with the one-way bearing 2 enables the existing grooving device to achieve synchronous grooving operations at both ends of the pipeline 9 without changing the original structure, only by replacing the original motor with the synchronous motor of the utility model.

That is, any equivalent changes and modifications made according to the content of the patent application scope of the present invention should be within the technical scope of the present invention.
