Description

Technical Field

[0001] This utility model relates to the field of speed reduction equipment technology, specifically to a parallel shaft speed reducer with adjustable pitch. Background Technology

[0002] A parallel shaft reducer is a type of reducer with parallel gear shafts. It is a power transmission mechanism that uses gears to reduce the rotational speed of a motor to a desired speed while obtaining a larger torque. Parallel shaft reducers have a wide range of applications in mechanisms used to transmit power and motion.

[0003] Existing parallel shaft reducers often have a fixed parallel shaft transmission pitch. Changing the pitch without changing the gear ratio usually requires redesigning the housing and changing the size and number of internal gears, which increases production time and cost and limits the scope of application. At the same time, during long-term operation, the oil level inside the reducer will gradually decrease, which will prevent the meshing position of the internal gear set from fully contacting the oil for lubrication and cooling, resulting in wear between the gears and greatly reducing the service life of the device. Therefore, an adjustable pitch parallel shaft reducer is proposed. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a parallel shaft reducer with adjustable pitch to solve the technical problems mentioned in the background.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a parallel shaft reducer with adjustable spacing, comprising a housing, an adjustment component on one side of the housing, and an oil injection component at the lower end of the housing interior;

[0006] The adjustment assembly includes a sealing ring installed on one side of the inner wall of the housing. A movable disk is rotatably connected to the inner wall of the sealing ring. A horizontal shaft is rotatably connected to the movable disk away from the center. A first gear is fixed to one end of the curved outer wall of the horizontal shaft. Multiple sets of screw holes are opened on the side of the movable disk away from the first gear. Matching bolts are installed in the screw holes. A second gear is provided at the bottom of the first gear. A crankshaft is fixed to one side of the second gear. A third gear is fixed at the end of the crankshaft away from the second gear. A fourth gear is provided at the bottom of the third gear.

[0007] As a preferred technical solution, the fuel injection assembly includes a movable rod rotatably connected to the middle of the crankshaft, a piston rotatably connected to the bottom end of the movable rod, an oil tank slidably connected to the outer wall of the piston, a connecting pipe on one side of the oil tank, an arc-shaped nozzle at the end of the connecting pipe away from the oil tank, and a fuel injection pipe connected to the front end of the oil tank.

[0008] As a preferred technical solution, the other end of the horizontal shaft passes through one side of the outer wall of the housing and is provided with a motor mounting plate, and a drive shaft is horizontally mounted at the center of the fourth gear.

[0009] As a preferred technical solution, the outer wall of the horizontal curved surface is provided with a marking ring, and the shell is provided with a scale on one side.

[0010] As a preferred technical solution, the housing has an arc-shaped groove for sliding the horizontal axis on the side near the motor mounting plate, and the scale is located above the arc-shaped groove.

[0011] As a preferred technical solution, the oil tank is provided with an oil suction pipe on the side away from the connecting pipe, the arc-shaped nozzle is provided at the meshing point of the first gear and the second gear, and the oil injection pipe is provided at the meshing point of the third gear and the fourth gear.

[0012] In summary, the present invention has the following main advantages:

[0013] This invention allows the horizontal shaft to move along the arc-shaped groove by unscrewing the bolts, thereby adjusting the distance between the horizontal shaft and the drive shaft. This effectively avoids gear misalignment and abnormal wear caused by non-parallel axes. It also allows for flexible matching of different specifications of motors or load shafts, reducing customization costs, thereby improving transmission efficiency and reducing vibration and noise. When the crankshaft rotates, it drives the movable rod and piston to reciprocate and move up and down, squeezing the oil. This lubricates and cools the meshing joint of the arc-shaped nozzle and the oil injection pipe gear set, effectively preventing the oil level inside the housing from dropping over time, which would prevent lubrication and cooling at the gear meshing joint and cause wear between the gears. This further enhances the service life of the device. Attached Figure Description

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0024] The embodiments of this utility model will be described below based on its overall structure.

[0025] A type of adjustable-pitch parallel shaft reducer, such as Figure 1-6 As shown, it includes a housing 100, an adjustment component 200 is provided on one side of the housing 100, and an oil injection component 300 is provided at the lower end of the interior of the housing 100;

[0026] The adjustment assembly 200 includes a sealing ring 210 installed on one side of the inner wall of the housing 100. A movable disk 220 is rotatably connected to the inner wall of the sealing ring 210. A horizontal shaft 230 is rotatably connected to the movable disk 220 away from the center. A first gear 240 is fixed to one end of the curved outer wall of the horizontal shaft 230. Multiple sets of screw holes 221 are opened on the side of the movable disk 220 away from the first gear 240. Matching bolts 222 are installed in the screw holes 221. A meshing second gear 250 is provided at the bottom of the first gear 240. A crankshaft 260 is fixed to one side of the second gear 250. A third gear 270 is fixed to the end of the crankshaft 260 away from the second gear 250. A meshing fourth gear 280 is provided at the bottom of the third gear 270.

[0027] When it is necessary to adjust the distance between the horizontal shaft 230 and the drive shaft 120, the operator unscrews the bolt 222 to release the fixation between the movable plate 220 and the housing 100. Then, by pulling the horizontal shaft 230, the horizontal shaft 230 moves along the arc groove 233. At the same time, the horizontal shaft 230 drives the first gear 240 to rotate around the second gear 250, thereby realizing the adjustment of the distance between the horizontal shaft 230 and the drive shaft 120. This can effectively avoid gear misalignment and abnormal wear caused by non-parallel axes. It can also flexibly match the connection positions of motors or load shafts of different specifications, reduce customization costs, and thus improve transmission efficiency and reduce vibration and noise.

[0028] Please refer to this carefully. Figures 3 to 6 The fuel injection assembly 300 includes a movable rod 310 rotatably connected to the middle of the crankshaft 260, a piston 320 rotatably connected to the bottom end of the movable rod 310, an oil tank 330 slidably connected to the outer wall of the piston 320, a connecting pipe 340 on one side of the oil tank 330, an arc-shaped nozzle 350 at the end of the connecting pipe 340 away from the oil tank 330, a fuel injection pipe 360 ​​connected to the front end of the oil tank 330, a suction pipe 331 on the side of the oil tank 330 away from the connecting pipe 340, the arc-shaped nozzle 350 being located at the meshing point of the first gear 240 and the second gear 250, and the fuel injection pipe 360 ​​being located at the meshing point of the third gear 270 and the fourth gear 280.

[0029] When the first gear 240 drives the second gear 250 to rotate, the second gear 250 drives the crankshaft 260 to rotate synchronously. The crankshaft 260 drives the movable rod 310 to move back and forth, thereby causing the piston 320 to squeeze the oil inside the oil tank 330. The oil is then sprayed out from the arc-shaped nozzle 350 through the connecting pipe 340 to lubricate and cool the meshing point of the first gear 240 and the second gear 250. The arc-shaped nozzle 350 can effectively lubricate the horizontal shaft 230 even when the spacing is adjusted. At the same time, oil is also sprayed out from the oil spray pipe 360 ​​to lubricate and cool the meshing point of the third gear 270 and the fourth gear 280. This effectively avoids the oil level inside the housing 100 from dropping due to prolonged use, which would prevent the meshing point of the gear set from being lubricated and cooled, thus causing wear between the gear sets and further enhancing the service life of the device.

[0030] Please refer to this carefully. Figures 1 to 4 The other end of the horizontal shaft 230 passes through one side of the outer wall of the housing 100 and is provided with a motor mounting plate 110. The fourth gear 280 is horizontally mounted with a drive shaft 120. The curved outer wall of the horizontal shaft 230 is provided with a marking ring 231, and the housing 100 is provided with a scale 232 on one side.

[0031] By mounting a servo motor on the motor mounting plate 110 and connecting it to the horizontal shaft 230, the speed reducer can be operated. The adjusted distance can be clearly defined by the cooperation of the marking ring 231 and the scale 232.

[0032] Please refer to this carefully. Figure 2 The housing 100 has an arc-shaped groove 233 on the side near the motor mounting plate 110 for sliding of the horizontal shaft 230, and the scale 232 is located above the arc-shaped groove 233.

[0033] The arc-shaped groove 233 makes the horizontal axis 230 more stable when moving during spacing adjustment.

[0034] In use, by unscrewing bolt 222, the horizontal shaft 230 is moved along the arc groove 233, thereby adjusting the distance between the horizontal shaft 230 and the drive shaft 120. This effectively avoids gear misalignment and abnormal wear caused by non-parallel axes. It also allows for flexible matching of different specifications of motors or load shafts, reducing customization costs, thereby improving transmission efficiency and reducing vibration and noise. When the crankshaft 260 rotates, it drives the movable rod 310 and piston 320 to reciprocate and move up and down, squeezing the oil. This lubricates and cools the meshing joint of the arc nozzle 350 and the oil injection pipe 360 ​​gear set, effectively preventing the oil level inside the housing 100 from dropping over time, which would prevent lubrication and cooling at the gear meshing joint and cause wear between the gears. This further enhances the service life of the device. All parts not mentioned in this device are the same as or can be implemented using existing technology.
