Description

Technical Field

[0001] This utility model relates to the field of motor technology, and in particular to a motor with a novel screw clearance groove structure. Background Technology

[0002] In traditional motor design, the fit between the end cover and the machined surface and crescent region of the rotating body often presents the following problems:

[0003] After the motor is finished, the machined surface of the end cover rotating body has a large runout, which leads to insufficient contact between the screw and the mating surface, affecting the stability and running accuracy of the motor.

[0004] Due to the design of the crescent-shaped area, traditional machining processes often cannot avoid the situation where the crescent-shaped area is higher than the machined surface of the rotating body during turning. This results in the screw only contacting the crescent-shaped area, while the machined surface of the rotating body is suspended, thus affecting the tightening effect of the screw.

[0005] To address these issues, this invention provides an optimized design, employing a crescent-shaped area lower than the machined surface of the rotating body and an optimized end cap structure. This improves the contact and fit accuracy between the screw and the machined surface of the rotating body, reduces runout after the motor is finished, and effectively enhances the motor's operational stability. Utility Model Content

[0006] This utility model relates to a motor structure design, and more particularly to a motor with a novel screw clearance groove structure. By optimizing the design of the end caps and sprocket caps, this motor solves the vibration problems caused by insufficient screw fit and unsupported machining surfaces of rotating parts during assembly in traditional motors, thereby improving the motor's assembly accuracy, stability, and service life.

[0007] The novel screw clearance groove structure motor provided by this utility model includes:

[0008] End caps and sprocket caps:

[0009] The end caps and sprocket caps are circular and symmetrically arranged coaxially. They are connected together by a shaft.

[0010] Both the end cap and the sprocket cover have a sealing end face on one side wall opposite to each other, which is sealed with the steel ring by the end cap screw.

[0011] Machining surfaces of rotating bodies:

[0012] The outer walls of the end caps and sprocket caps are provided with rotating surfaces, and the screws are in full contact with the rotating surfaces.

[0013] The bottom surface of the crescent-shaped area is lower than the machined surface of the rotating body, which avoids the problem of the crescent-shaped area being higher than the machined surface of the rotating body and ensures that the screw is in close contact with the machined surface of the rotating body.

[0014] Crescent area:

[0015] The outer side wall of the end cover and the sprocket cover is provided with a crescent area for screw fitting. The crescent area is specially designed to have a bottom surface lower than the surface of the rotary body, so as to ensure sufficient contact between the screw and the surface of the rotary body during installation, and avoid poor contact of the screw caused by the crescent area being higher than the surface of the rotary body in the traditional design.

[0016] The shaft serves as a connecting shaft of the end cover and the sprocket cover, and provides stable support.

[0017] The iron core support and the iron core provide magnetic field generation and support for the motor, and the winding is embedded in the iron core for generating electromagnetic force to drive the motor to rotate.

[0018] The steel ring is fitted with the end cover screw through the sealing end surface, so as to ensure the sealing of the motor.

[0019] The oil seal and the bearing ensure smooth rotation of the shaft, and reduce friction and wear.

[0020] The sprocket and the coupling disc are used for transmitting power of the motor to external equipment.

[0021] The beneficial effects of the utility model are as follows:

[0022] 1. Reduce the bounce: through the sinking design of the crescent area, the screw is fully contacted with the surface of the rotary body, so as to reduce the bounce of the motor after finishing, and improve the motor precision.

[0023] 2. Improve the fitting precision: the flatness of the surface of the rotary body is optimized, so that the screw and the end cover are more closely fitted, the stress uniformity of the motor is ensured, and the problems of insufficient fitting or screw loosening are avoided.

[0024] 3. Enhance the sealing and stability: through the cooperation design of the sealing end surface and the steel ring, the inside of the motor is effectively sealed, external pollutants are prevented from entering, and the service life and reliability of the motor are improved.

[0025] The above description is only a summary of the technical scheme of the utility model, in order to more clearly understand the technical means of the utility model, which can be implemented according to the content of the specification, and in order to make the above and other purposes, characteristics and advantages of the utility model more obvious and easy to understand, the following preferred embodiments are described in detail, and the accompanying drawings are described as follows.

The following is the specific implementation of the technical scheme:

[0037] 1. The structural design of end cover and sprocket cover

[0038] End cover 1 and sprocket cover 2:

[0039] End cover 1 and sprocket cover 2 are circular and are coaxially and symmetrically arranged. The coaxial structure of the two not only enhances the overall stability of the motor shell, but also enables the end cover and the sprocket cover to be accurately connected during installation, ensuring the sealing and durability of the motor.

[0040] The same shaft 6 is inserted at the center of the end cover 1 and the sprocket cover 2, which plays a supporting and connecting role, ensures the stable fixation of the end cover and the sprocket cover, and reduces the friction between the components.

[0052] Since the bottom surface of the crescent area 19 is lower than the rotary body machining surface 18, the rotary body machining surface 18 always remains flat and can effectively disperse the stress when cooperating with the screw, thereby improving the stability and durability of the motor.

[0053] 5. Design of iron core and winding

[0054] Iron core support 7 and iron core 8:

[0055] The iron core support 7 is sleeved on the outer peripheral surface of the shaft 6, which provides support and ensures the fixation of the iron core 8, avoiding displacement of the iron core.

[0057] The winding 9 is connected to the external circuit through the wire harness 10, and the end of the wire harness 10 passes through the shaft 6 and extends to the outside of the end cover 1. In this way, the electrical connection of the winding facilitates subsequent maintenance and repair.

[0058] 6. Other accessory designs

[0059] Steel ring 4 and rim 16:

[0060] The steel ring 4 is fixedly connected with the sealing end face 17, which enhances the sealing of the motor outside and ensures the stability of the structure.

[0061] The steel ring 4 is sleeved with the rim 16 on the outer peripheral surface, which provides additional protection for the motor to prevent external impact from damaging the external structure of the motor.

[0062] Bearing 14 and oil seal 15:

[0063] The bearing 14 and the oil seal 15 are both arranged at the center position of the inner wall of the end cover 1 and the sprocket cover 2, and are coaxially sleeved with the shaft 6. The bearing provides support for the rotating part of the motor, reduces friction, and ensures stable operation of the shaft.

[0064] The oil seal 15 works together with the bearing 14 to prevent oil leakage and ensure long-term stable operation of the motor.

[0065] 7. Design of sprocket and coupling disc

[0066] Sprocket cover 2 and coupling disc 12:

[0067] The coupling disc 12 is coaxially arranged on one side of the outer wall of the sprocket cover 2. The coupling disc 12 is connected with the sprocket cover 2 through the coupling disc screw 13, ensuring the connection and fastening between the sprocket and the coupling disc.

[0068] The sprocket 11 is arranged on the side wall of the coupling disc 12, which is tightly connected with the coupling disc through bolts, ensuring the stable operation of the sprocket and preventing the sprocket from loosening or falling off.

[0069] 8. Overall assembly

[0070] During assembly, first, the end cover 1 and the sprocket cover 2 are butted through the shaft 6, and the end cover screw 3 is fixedly connected with the steel ring 4, ensuring that the various components inside the motor are fixed and sealed.

[0071] The core support 7 and the core 8 are fixed between the end cover and the sprocket cover through the shaft 6, and the winding 9 is connected with the power supply through the wire harness 10.

[0072] The sprocket 11 is connected with the sprocket cover 2 through the coupling disc 12, ensuring the stability of the transmission part.

[0073] Working principle

[0074] The working principle of the screw slot new structure motor mainly lies in ensuring the stability, sealing and long-term reliability of the motor during operation by optimizing the design of the end cover and the sprocket cover. The working principle of each component of the motor will be described in detail below.

[0075] Basic components and functions of the motor

[0076] The core components of the motor include:

[0077] End cover 1 and sprocket cover 2: play a role in protecting, sealing and fixing the internal components of the motor, ensuring normal operation of the motor and preventing foreign matter from entering.

[0078] Rotary body processing surface 18: This is the processing surface of the motor housing, the screw contacts the rotary body processing surface, ensuring the fastening of the external connection.

[0079] Crescent area 19: specially designed to provide a matching space for the end cover screw 3, ensuring that the screw is in full contact with the rotary body processing surface when fastened.

[0080] Steel ring 4: forms a seal with the end cover and sprocket cover, preventing leakage inside the motor.

[0081] Iron core support 7 and iron core 8: provide support for the electrical part of the motor, and the winding 9 is embedded for current conduction.

[0082] Winding 9 and wire harness 10: the winding inside the motor generates electromagnetic force, making the motor rotate, and the wire harness is used to introduce electrical energy into the winding.

[0083] Working process of the motor

[0084] When the motor starts, the current is delivered to the winding 9 through the wire harness 10, generating an electromagnetic field. The electromagnetic field interacts with the iron core 8 inside the motor, generating a rotating magnetic field. This rotating magnetic field drives the shaft 6 to rotate, thereby driving the motor to operate.

[0085] The shaft 6 transmits the rotating power by being inserted into the design of the end cover 1 and the sprocket cover 2, while the rotation of the shaft drives the transmission part connected outside to work.

[0086] The sealing design of the end cover 1 and the sprocket cover 2 ensures the stability of the motor during operation, preventing moisture or dust from entering the inside of the motor, thereby avoiding damage to the motor. The steel ring 4 is connected with the end cover screw 3 through the sealing end surface 17, ensuring the sealing and stability of the motor housing.

[0087] Working principle of the improved structure

[0088] Improved design of the crescent area 19: The bottom surface of the crescent area 19 is lower than the rotary body machining surface 18, ensuring that during machining of the rotary body machining surface, the screw will not be insufficiently in contact with the crescent area. The screw is in full contact with the end cover rotary body machining surface, and the force is more uniform, effectively improving the stability of the motor during operation. In this way, the runout of the rotary body machining surface of the finished motor is effectively reduced, thereby improving the precision and reliability of the motor.

[0089] Rotary body machining surface 18: When the motor housing is machined, the rotary body machining surface provides a smooth and precise contact surface, allowing the end cover screw to tightly fit with the motor housing, avoiding loose or incomplete fitting of the screw. This effectively avoids loose or errors caused by insufficient contact.

[0090] Function of the core support 7 and the core 8: The core 8 has a winding 9 embedded inside, which generates a magnetic field under the action of current, driving the motor to rotate. The core support 7 is used to support the core, ensuring smooth current conduction of the winding and stable generation of electromagnetic field.

[0091] Coordination of power transmission and sealing system

[0092] Sprocket 11 and coupling disc 12: The sprocket 11 is connected to the sprocket cover 2 through the coupling disc 12, forming a power transmission channel between the motor and external load. When the motor is running, the sprocket transmits the rotating power to the coupling disc, which then drives other mechanical components through external transmission devices.

[0093] Oil seal 15 and bearing 14: The oil seal 15 and bearing 14 work together on the rotating parts of the motor, providing lubrication and reducing friction, ensuring smooth operation of the motor.

[0094] Rim 16: The design of the rim adds a protective shell layer to the outside of the motor, enhancing the structural strength of the motor and serving as a protective function to prevent external impact on the motor.

[0095] During the start-up and operation of the motor, thanks to the improved design, the screw can be in full contact with the end cover rotary body machining surface, and the force is uniform, reducing vibrations or runout caused by uneven force. The stability and precision of the motor are significantly improved.

[0096] Through the sinking design of the crescent area, the problem of poor contact between the screw and the crescent area is avoided, making it possible for the screw to tightly fit with the rotary body machining surface, further improving the assembly precision of the motor.

[0097] With the design of sealed end face, steel ring, oil seal, and bearing, the long-term stable operation of the motor is ensured, and the intrusion of external pollutants is avoided.

[0098] Through the design and structural improvement, the motor can work efficiently and stably, reduces the loss caused by poor structure, and improves the overall performance of the motor
