Description

Technical Field

[0001] The utility model relates to the technical field of motor shafts, in particular to a motor shaft with a supporting structure. Background Art

[0002] The motor shaft is a rotating shaft in the motor used to connect the load and output power. It is usually composed of the motor's rotor and bearings and other components. Its main function is to convert electrical energy into mechanical energy and generate mechanical power through rotation, and then support and transmit this power to the load through bearings and other components to enable it to work normally. In addition, the motor shaft can also reduce wear and friction by selecting suitable materials and lubrication methods, thereby extending its service life. The structure and design of the motor shaft will also be adjusted and optimized according to different application scenarios and special needs to ensure its normal operation and reliability. When the motor shaft is not long enough, a transmission shaft needs to be connected to the surface of the motor shaft. This will cause the external transmission shaft to shake during transmission, affecting the normal use of the motor, so external support is required.

[0003] The patent with application number CN202321624333.2 provides a DC brushless motor shaft. The DC brushless motor shaft includes: a mounting block; a connecting sleeve, the connecting sleeve is arranged on the mounting block, a main shaft is arranged inside the connecting sleeve, a plurality of grooves are provided inside the connecting sleeve, balls are arranged inside the grooves, and the balls are in contact with the main shaft. The DC brushless motor shaft provided by the utility model mounts the main shaft on the motor housing through the mounting block. When the main shaft rotates, the main shaft rotates on the surface of the balls. At this time, the balls roll between the main shafts, so that the friction force is smaller when the main shaft rotates. By converting the sliding friction of the main shaft into rolling friction, the friction force during rotation is greatly reduced, thereby reducing kinetic energy loss and playing a role in environmental protection and energy saving.

[0004] However, the motor shaft of the patented motor still has shaking and instability problems when it is driven by an external transmission shaft.

[0005] Therefore, it is necessary to provide a new technical solution to overcome the above-mentioned defects. Utility Model Content

[0006] The purpose of the utility model is to provide a motor shaft with a supporting structure which can effectively solve the above technical problems.

[0007] In order to achieve the purpose of the utility model, the following technical scheme is adopted: comprising: a motor, a motor shaft, a transmission shaft, a support assembly for supporting the motor shaft, and a reinforcement assembly for supporting the transmission shaft;

[0008] The support assembly comprises: a support plate threadedly mounted on the motor, and a bearing mounted on the support plate;

[0009] The reinforcement assembly comprises: a reinforcement plate for reinforcing the transmission shaft and a pressure rod for pushing the reinforcement plate to move.

[0010] Furthermore, the support assembly also includes: a slot opened on the motor shaft, a block slidably connected to the slot, an oil chamber for storing lubricating oil, an oil baffle cover hinged on the support plate, a threaded rod threadedly connected to the oil baffle cover, an oil squeezing plate rotatably connected to the threaded rod, and an oil hole opened on the oil chamber.

[0011] Furthermore, the support plate is fixedly connected to the clamping block, and a motor shaft is sleeved on the bearing.

[0013] Furthermore, the fixing frame is detachably connected to the supporting plate, a first rotating shaft is rotatably connected to the surface of the hinged rod, and a second rotating shaft is rotatably connected to the surface of the crank arm connecting rod.

[0014] Compared with the prior art, the utility model has the following beneficial effects: the utility model provides a motor shaft with a supporting structure, and the rotating threaded rod can drive the oil squeezing plate to slide inside the oil chamber through the threaded connection with the oil baffle cover. At the same time, the lubricating oil inside the oil chamber is squeezed out through the oil hole to lubricate the bearing. When the threaded rod rotates, it drives the pressure rod to move, and under the push of the pressure rod, it drives the articulated rod to rotate around the first rotation axis through the connecting plate, and at the same time drives the crank arm connecting rod to rotate around the second rotation axis, so that one end of the crank arm connecting rod pushes the other two groups of reinforcement plates to move toward the transmission shaft, thereby supporting and reinforcing the transmission shaft to avoid shaking and instability when the transmission shaft rotates.

[0022] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments of the utility model will be clearly and completely described below. Obviously, the described embodiments are partial embodiments of the utility model, rather than all embodiments.

[0023] In the description of the present utility model, it should be understood that the terms "center", "lateral", "longitudinal", "front", "back", "left", "right", "up", "down", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the scope of protection of the present utility model. When a mechanism is referred to as being "fixed to" another mechanism, it may be directly on the other mechanism or there may also be a centered mechanism. When a mechanism is considered to be "connected to" another mechanism, it may be directly connected to the other mechanism or there may be a centered mechanism at the same time. When a mechanism is considered to be "set on" another mechanism, it may be directly set on the other mechanism or there may be a centered mechanism at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0024] like Figures 1 to 5As shown, the utility model is a motor shaft with a supporting structure, comprising: a motor 1, a motor shaft 2, a transmission shaft 5, a support assembly 3 for supporting the motor shaft 2, and a reinforcement assembly 4 for supporting the transmission shaft 5. When the length of the motor shaft 2 needs to be extended, the transmission shaft 5 is connected to the motor shaft 2 through the reinforcement assembly 4 to extend it.

[0025] After the motor shaft 2 is connected to the transmission shaft 5, the rotational pressure of the motor shaft 2 and the transmission shaft 5 is large, and shaking and instability may occur easily, so they need to be supported.

[0026] The support assembly 3 includes: a support plate 33 threadedly mounted on the motor 1, a bearing 34 mounted on the support plate 33, the motor shaft 2 is sleeved on the bearing 34, the motor shaft 2 passes through the bearing 34 and the support plate 33, the support plate 33 is connected to the motor 1 through a thread, so that when the motor shaft 2 rotates, it can be prevented from shaking and being unstable through the support plate 33 and the bearing 34; the support assembly 3 also includes: a slot 31 provided on the motor shaft 2, a block 32 slidably connected to the slot 31, and the support plate 33 is connected to the motor shaft 2 through the slot 31 of the block 32. The support plate 33 is connected to the shaft 2, the support plate 33 is fixedly connected to the block 32, an oil chamber for storing lubricating oil, an oil baffle cover 35 hinged on the support plate 33, a threaded rod 36 threadedly connected to the oil baffle cover 35, an oil squeezing plate 37 rotatably connected to the threaded rod 36, and an oil hole 38 opened on the oil chamber. The rotating threaded rod 36 can drive the oil squeezing plate 37 to slide inside the oil chamber through the threaded connection with the oil baffle cover 35. At the same time, the lubricating oil inside the oil chamber is squeezed out through the oil hole 38 to lubricate the bearing 34, so that the rotation effect of the motor shaft 2 is stable and the transmission can be smoother.

[0027] The lubricating oil can be selected from the bearing 34 lubricating oil, which is generally semi-solid. In daily use, part of the lubricating oil naturally flows out through the oil hole 38 to lubricate the bearing 34. When the motor shaft 2 has high rotation intensity or other lubrication is required, the lubricating oil in the oil cavity is pushed out through the oil squeezing plate 37, which makes lubrication more convenient. The motor shaft 2 can also be lubricated while it is running, and the use effect is good.

[0028] The reinforcement component 4 includes: a reinforcement plate 44 for reinforcing the transmission shaft 5, and a pressure rod 42 for pushing the reinforcement plate 44 to move. The pressure rod 42 pushes the reinforcement plate 44 downward to squeeze and limit the transmission shaft 5 to avoid shaking and instability when the transmission shaft 5 rotates. Multiple groups of rollers are arranged on the surface of the reinforcement plate 44 to reduce the contact surface area between the reinforcement plate 44 and the transmission shaft 5, thereby reducing friction.

[0029] The reinforcement assembly 4 also includes: a connecting rod 41 detachably connected to the threaded rod 36, the connecting rod 41 is fixedly connected to the pressure rod 42, the pressure rod 42 is penetrated by a fixing frame 43, the fixing frame 43 is detachably connected to the support plate 33, the surface of the pressure rod 42 is fixedly connected to a connecting plate 45, a hinged rod 46 hinged at one end of the connecting plate 45, a crank arm connecting rod 48 hinged at one end of the hinged rod 46, the surface of the hinged rod 46 is rotatably connected to a rotating shaft 1 47, the surface of the crank arm connecting rod 48 is rotatably connected to a rotating shaft 2 49, and the crank arm connecting rod 48 is rotatably connected to a rotating shaft 2 49. The other end of the arm link 48 is abutted against a reinforcement plate 44. Three groups of reinforcement plates 44 are arranged at equal intervals with the axis of the transmission shaft 5 as the center. When one group of reinforcement plates 44 is in use, the rotating threaded rod 36 drives the pressure rod 42 to move, and under the push of the pressure rod 42, the hinged rod 46 is driven to rotate around the rotation axis 1 47 through the connecting plate 45, and at the same time drives the crank arm link 48 to rotate around the rotation axis 2 49, so that one end of the crank arm link 48 pushes the other two groups of reinforcement plates 44 to move toward the transmission shaft 5, so as to reinforce the transmission shaft 5 and avoid shaking and instability when the transmission shaft 5 rotates.

[0030] In the present application, the motor shaft 2 is externally connected to the transmission shaft 5. In this case, the motor shaft 2 and the transmission shaft 5 are prone to shaking. The motor shaft 2 is reinforced to prevent shaking. At the same time, the transmission shaft 5 is also reinforced, which greatly reduces the possibility of shaking between the motor shaft 2 and the transmission shaft 5 and has a good use effect.

[0031] Another point that needs to be explained is that springs are installed on the surfaces of the pressure rods 42 on the other two sets of reinforcement plates 44. When the transmission rods are squeezed and fixed, the springs are deformed by the force, which facilitates the subsequent resetting of the reinforcement plates 44.

[0032] Working principle:

[0033] The rotating threaded rod 36 can drive the oil squeezing plate 37 to slide inside the oil chamber through the threaded connection with the oil baffle cover 35. At the same time, the lubricating oil inside the oil chamber is squeezed out through the oil hole 38 to lubricate the bearing 34. When the threaded rod 36 rotates, it drives the pressure rod 42 to move, and under the push of the pressure rod 42, it drives the hinged rod 46 to rotate around the rotating shaft 1 47 through the connecting plate 45, and at the same time drives the crank arm connecting rod 48 to rotate around the rotating shaft 2 49, so that one end of the crank arm connecting rod 48 pushes the other two groups of reinforcement plates 44 to move toward the transmission shaft 5, so as to reinforce the transmission shaft 5 and prevent the transmission shaft 5 from shaking when it rotates.
