Technical Field

[0001] The utility model relates to the technical field of speed reducers, and specifically, to a speed reducer with displacement control. Background Art

[0002] Generally speaking, a speed reducer is a power transmission mechanism that uses a gear speed converter to reduce the rotational speed of a motor or a motor to the required rotational speed and obtain a larger torque.

[0008] According to the above design scheme, the rack and the gear are meshed with each other, and the gear and the half gear are meshed with each other. Such a design is conducive to driving the rack to perform reciprocating linear motion when the gear is forced to rotate counterclockwise.

The bottom of the inner wall of the outer shell is rotatably connected to the rotating shaft, and the circumferential surface of the rotating shaft is fixedly connected to a force-bearing wheel. Such a design is beneficial for the sprocket to pull the force-bearing wheel through the chain when the sprocket is forced to rotate clockwise.

[0018] 2. In the present utility model, through the mutual cooperation of components such as a rotating shaft, a sprocket, a fixed ring, and a fan blade, when the rotating shaft is forced to rotate clockwise, it drives the fixed ring to rotate clockwise, thereby causing the fan blade to rotate clockwise. When the fan blade rotates, it can store wind and blow the high temperature from the inside of the machine body to the outside, so that the high temperature does not accumulate at the bottom of the inner wall of the outer shell and can volatilize, reducing the displacement of the bearing and improving the safety of the operation of the machine body.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0026] Next, in combination with the embodiments of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the scope of protection of the present utility model.

[0027] Embodiment 1

[0028] As Figures 1 to 5 shown, this embodiment proposes a speed reducer with displacement control, including support legs 1 and a housing 2. The housing 2 is fixedly connected to the top of the support legs 1. A primary reduction mechanism 3 is provided on the inner wall of the housing 2, a secondary reduction mechanism 4 is provided on the inner wall of the housing 2, and a lubrication device 5 is provided at the bottom of the inner wall of the housing 2; the lubrication device 5 includes a motor 51, the motor 51 is fixedly penetrated through the bottom of the inner wall of the housing 2, the end of the output shaft of the motor 51 is fixedly connected to a rotating shaft 52, a semi-gear 53 is fixedly connected to the circumferential surface of the rotating shaft 52, a rotating rod 54 is rotatably connected to the bottom of the inner wall of the housing 2, a gear 55 is fixedly connected to the circumferential surface of the rotating rod 54, a chute 56 is opened at the bottom of the inner wall of the housing 2, a slider 57 is slidably connected to the inner wall of the chute 56, and a rack 58 is fixedly connected to the top of the slider 57.

[0029] The top of the rack 58 is fixedly connected to a force-bearing plate 59. A storage tank 510 is provided at the bottom of the inner wall of the housing 2. A piston 511 is slidably connected to the inner wall of the storage tank 510. A force-bearing rod 512 is fixedly connected to the side of the piston 511. A spring 513 is fixedly connected to the circumferential surface of the force-bearing rod 512. A spray pipe 514 is provided at the top of the storage tank 510. A torsion spring 515 is fixedly connected to the circumferential surface of the rotating rod 54. Such a design is beneficial for driving the force-bearing plate 59 to move in a reciprocating linear motion when the rack 58 makes a reciprocating linear motion.

[0030] The rack 58 meshes with the gear 55, and the gear 55 meshes with the semi-gear 53. Such a design is beneficial for driving the rack 58 to move in a reciprocating linear motion when the gear 55 is forced to rotate counterclockwise.

[0031] In this embodiment, first, when the staff starts working, the external power supply is turned on to start the motor 51, forcing the rotating shaft 52 to rotate clockwise. When the rotating shaft 52 rotates clockwise, it drives the semi-gear 53 to rotate clockwise under force, causing the gear 55 meshing with the semi-gear 53 to rotate counterclockwise through the rotating rod 54. When the semi-gear 53 moves to a position where it no longer meshes with the gear 55, the torsion spring 515 fixed on the circumferential surface of the rotating rod 54 uses its own torsion force to drive the gear 55 to reset, forcing the rack 58 meshing with the gear 55 to make a reciprocating linear motion on the inner wall of the chute 56 through the slider 57. When the rack 58 makes a reciprocating linear motion, it drives the force-receiving plate 59 fixed on the top of the rack 58 to make a reciprocating linear motion. When the force-receiving plate 59 makes a reciprocating linear motion, it intermittently pats the force-receiving rod 512. When the force-receiving plate 59 pushes the force-receiving rod 512 to move inside the storage tank 510, the piston 511 is forced to slide on the inner wall of the storage tank 510, causing the inside of the storage tank 510 to be squeezed and spraying the lubricating oil from the spray pipe 514 to the place where lubrication is needed. Conversely, when the rack 58 moves towards the end away from the force-receiving rod 512, the force-receiving rod 512 can reset by using the elastic force of the spring 513. This cycle ensures that the spray pipe 514 intermittently sprays lubricating oil, guaranteeing the service life of the machine parts and improving the work efficiency of the staff.

[0032] Embodiment 2

[0033] As Figures 1 to 5 shown, on the premise of the same concept as the above Embodiment 1, a second embodiment is also proposed. A cooling device 6 is provided at the bottom of the inner wall of the housing 2. The cooling device 6 includes a sprocket 61, and the sprocket 61 is fixedly connected to the circumferential surface of the rotating shaft 52. A chain 62 is meshed with the circumferential surface of the sprocket 61. A rotating shaft 63 is rotatably connected to the bottom of the inner wall of the housing 2, and a force-receiving wheel 64 is fixedly connected to the circumferential surface of the rotating shaft 63. Such a design is beneficial for when the sprocket 61 is forced to rotate clockwise, the sprocket 61 can pull the force-receiving wheel 64 through the chain 62.

[0034] A fixing ring 65 is fixedly connected to the circumferential surface of the rotating shaft 63, and a fan blade 66 is fixedly connected to the circumferential surface of the fixing ring 65. Such a design is beneficial for when the rotating shaft 63 is forced to rotate clockwise, driving the fixing ring 65 to rotate clockwise.

[0035] The chain 62 is drivingly connected to the circumferential surface of the force-receiving wheel 64, and the fixing ring 65 is located directly above the force-receiving wheel 64. Such a design is beneficial for when the force-receiving wheel 64 rotates clockwise, it can drive the rotating shaft 63 to rotate clockwise.

[0036] The force-receiving plate 59 is arranged in an L shape, and the force-receiving plate 59 is at the same height as the force-receiving rod 512. Such a design is beneficial for when the force-receiving plate 59 makes a reciprocating linear motion, the force-receiving plate 59 can intermittently pat the force-receiving rod 512.

[0037] There are two nozzle pipes 514, and the nozzle pipes 514 are aligned with the meshing position of the first-stage reduction mechanism 3 and the second-stage reduction mechanism 4. Such a design is beneficial for the nozzle pipes 514 to accurately align with the places where lubricating oil needs to be sprayed.

[0038] There are several fan blades 66, and they are circumferentially arrayed on the circumferential surface of the fixed ring 65. Such a design is beneficial for driving the fan blades 66 to rotate clockwise when the fixed ring 65 rotates clockwise.

[0039] There are several support legs 1, and they are symmetrically arranged along the vertical central axis of the bottom of the housing 2. Such a design is beneficial for the support legs 1 to support the entire machine body.

[0040] In this embodiment, in the lubrication device 5, when the lubrication device 5 is working normally, since a large amount of heat is generated during the operation of each reduction mechanism, which causes high temperature inside the machine body, and the temperature can affect the displacement control of the speed reducer. In order to avoid the generation of a large amount of high temperature, when the rotating shaft 52 rotates clockwise, it drives the sprocket 61 to rotate clockwise, so that the sprocket 61 drives the force-bearing wheel 64 to rotate clockwise through the chain 62 and the rotating shaft 63. When the rotating shaft 63 is forced to rotate clockwise, it drives the fixed ring 65 to rotate clockwise, thereby prompting the fan blades 66 to rotate clockwise. When the fan blades 66 rotate, they can store wind and blow the high temperature from the inside of the machine body to the outside, so that the high temperature does not accumulate at the bottom inner wall of the housing 2 and can volatilize, reducing the displacement of the bearing and improving the safety of the operation of the machine body.

[0041] The above is only the preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
