Description

Technical Field

[0001] The present invention relates to the technical field of inter-tooth transmission of a reducer, and more specifically to an inter-tooth transmission device for a reducer. Background Art

[0002] The reducer plays the role of matching speed and transmitting torque between the prime mover and the working machine or actuator, and is widely used in modern machinery. Reducers can be divided into two categories according to their uses: general reducers and special reducers. The design, manufacturing and use characteristics of the two are different.

[0003] During the operation of the reducer, the purpose of adjusting the speed is achieved through the matching ratio between the gears. There will be a transmission device between the power input shaft and the output shaft of the speed regulating component, and its purpose is to adjust the speed by multiple matching ratios.

[0004] There are some problems in the use of the inter-tooth transmission device of the existing reducer, which are as follows: the existing inter-tooth transmission device adjusts the speed in multiple stages through the speed ratio between the gears, so that the speed adjustment does not affect the normal service life of the gears. However, during the long-term mutual meshing of the gears, some metal debris caused by the friction between the gears will exist between the gears. If these debris exist in the meshing parts of the two gears for a long time, the wear of the teeth of the gears will increase during the meshing process, resulting in a reduction in the service life of the gears.

[0015] Technical effects and advantages of the present invention:

[0016] 1. The present invention makes the first transmission gear away from the input gear so that the first transmission gear and the input gear no longer remain in meshing, then the input gear rotates to drive the transmission teeth and the positioning ring plate to rotate relative to the positioning sleeve, and then the positioning shaft is pushed through the arc groove, and the arc positioning plate and the arc cleaning block are away from the center of the positioning block under the positioning of the limit bar so that the outer side of the arc cleaning block coincides with the outer side of the transmission teeth, and then the arc cleaning block sinks and gets stuck into the inner side of the input gear teeth during the process of the input gear rotating to drive the transmission teeth to rotate, and then the arc cleaning block cleans the debris in the input gear, and after the cleaning is completed, the input gear rotates in the reverse direction so that the cleaning component returns to the original position, and then the compressor works in the reverse direction to extract the liquid in the arc sleeve, so that the first transmission gear returns to the original position and meshes with the input gear, and then the servo motor rotates so that the circular hole opened on the outer side of the conveying cylinder and the conveying pipe are completely staggered, so that the debris between the gaps between the gears can be cleaned, and the service life of the reducer is effectively guaranteed.

[0017] 2. In the process that the output shaft of the present invention needs to rotate in the reverse direction, the servo motor first drives the flow dividing column and the conveying cylinder to rotate under the positioning of the connecting pipe, so that the center of the circular hole opened on the outer side of the conveying cylinder and the center of the circle between the conveying pipes are in the same straight line, and then the compressor works to extract the liquid in the hydraulic cylinder through the backflow pipe and inject it into the conveying cylinder through the U-shaped pipe and the connecting pipe, and then the liquid enters the space between the flow dividing column and the conveying cylinder under the diversion of the flow dividing column, and then the liquid enters the interior of the arc sleeve along the circular hole opened on the outer side of the conveying cylinder and the conveying pipe under the condition of increased internal pressure, and then pushes the arc limit plate to move to a position away from the limit baffle, and then pushes the arc telescopic The plate and the first transmission gear are away from the limit baffle, thereby making the two first transmission gears away from the input gear. Then, during the reverse rotation of the output shaft, only the second transmission gear can be driven to rotate, and the input gear will not be driven to rotate through the first transmission gear to avoid the reverse rotation of the output shaft driving the motor output shaft to rotate in the opposite direction, causing damage to the motor. The motor of the reducer can be installed with a one-way motor, thereby reducing the cost of the reducer. After the reverse rotation is completed, the liquid inside the arc sleeve is extracted through the reverse work of the compressor, so that the first transmission gear returns to its original position and meshes with the input gear, and then the servo motor is rotated to make the circular hole opened on the outside of the conveying cylinder and the conveying pipe completely staggered.

[0018] 3. In the process of speed regulation, the present invention drives the input shaft to rotate through the motor, which in turn drives the input gear to rotate, which in turn drives the first transmission gear to rotate, which in turn drives the positioning sleeve to rotate through the arc-shaped telescopic mechanism, which in turn drives the connecting circular plate to rotate, which in turn drives the second transmission gear to rotate, and at the same time drives the conveying cylinder and the limit ring to rotate relative to the connecting pipe, and then drives the output gear and the output shaft to rotate through the second transmission gear to complete the speed regulation, thereby meeting the speed regulation requirements of the equipment.

[0037] In a preferred embodiment, the angle between the guide hole 20112 on the outside of the positioning sleeve 20111 near the front and the guide hole 20112 near the back is forty-five degrees, a circular hole corresponding to the guide hole 20112 is opened on the outside of the conveying cylinder 2019, and the angle between the circular hole on the outside of the conveying cylinder 2019 near the front and the circular hole near the back is forty-five degrees, the back of the connecting circular plate 20114 is fixedly connected to the front of the second transmission gear 204, and the front of the servo motor 20113 is fixedly connected to the back of the second transmission gear 204;

[0038] The input shaft 102 is driven by the motor to rotate, which in turn drives the input gear 103 to rotate, and then drives the first transmission gear 2021 to rotate, and then drives the positioning sleeve 20111 to rotate through the arc-shaped telescopic mechanism 2023, and then drives the connecting circular plate 20114 to rotate, and then drives the second transmission gear 204 to rotate, and at the same time drives the conveying cylinder 2019 and the limit ring 2018 to rotate relative to the connecting tube 2015, and then drives the output gear 105 and the output shaft 104 to rotate through the second transmission gear 204 to complete the speed regulation, thereby meeting the equipment's demand for speed regulation.

[0039] In a preferred embodiment, the shape of the sliding slot 2022 is the same as that of the arc telescopic mechanism 2023, the size of the sliding slot 2022 and the size of the arc telescopic mechanism 2023 have a tolerance match, the connection position of the delivery pipe 20232 and the arc sleeve 20231 is located between the limit baffle 20233 and the front inside the arc sleeve 20231, the size inside the arc sleeve 20231 and the size of the arc limit plate 20234 have a tolerance match, the opening size on the back of the arc sleeve 20231 and the cross-sectional size of the arc telescopic plate 20235 have a tolerance match, and the arc telescopic mechanism 2023 located on the front outside of the positioning sleeve 20111 is fixedly connected to the first transmission gear 2021 located on the back;

[0040] When the output shaft 104 needs to rotate in the opposite direction, the servo motor 20113 first drives the diverter column 20110 and the conveying cylinder 2019 to rotate under the positioning of the connecting pipe 2015, so that the center of the circular hole opened on the outside of the conveying cylinder 2019 is in the same straight line with the center of the circle between the conveying tube 20232, and then the compressor 2013 works to extract the liquid in the hydraulic cylinder 2011 through the backflow pipe 2012 and inject it into the conveying cylinder 2019 through the U-shaped tube 2014 and the connecting pipe 2015, and then under the diversion of the diverter column 20110, the liquid enters the space between the diverter column 20110 and the conveying cylinder 2019, and then when the internal pressure increases, the liquid enters the interior of the arc sleeve 20231 along the circular hole opened on the outside of the conveying cylinder 2019 and the conveying tube 20232, and then pushes the arc limit plate 20234 to a position away from the limit baffle 20233. The position moves and then pushes the arc-shaped telescopic plate 20235 and the first transmission gear 2021 away from the limit baffle 20233, thereby making the two first transmission gears 2021 away from the input gear 103, and then in the process of the reverse rotation of the output shaft 104, it can only drive the second transmission gear 204 to rotate, and will not drive the input gear 103 to rotate through the first transmission gear 2021 to avoid the reverse rotation of the output shaft 104 driving the motor output shaft to rotate in the opposite direction, causing damage to the motor, so that the motor of the reducer can be installed with a one-way motor, resulting in a reduction in the cost of the reducer. After the reverse rotation is completed, the compressor 2013 works in the reverse direction to extract the liquid inside the arc-shaped sleeve 20231, so that the first transmission gear 2021 returns to its original position and meshes with the input gear 103, and then the servo motor 20113 rotates to make the circular hole opened on the outside of the conveying cylinder 2019 and the conveying pipe 20232 completely staggered.

[0041] In a preferred embodiment, the width of the square groove 2032 is the same as the width of the arc groove 2036, the width of the square groove 2032 and the diameter of the positioning shaft 2033 cooperate with each other, the transmission teeth 2035 and the teeth on the outer side of the first transmission gear 2021 have the same shape and overlap with each other, the inner side of the positioning block 2031 and the outer side of the arc sleeve 20231 are connected by a limit assembly, which can limit the positioning block 2031 from rotating relative to the outer side of the positioning block 2031, and the inner side of the positioning block 2031 is connected to the outer side of the positioning sleeve 20111 through the gap between the two positioning blocks 2031, the positioning ring plate 2034 and the positioning block 2031 can rotate relative to each other, and the connection between the positioning shaft 2033 and the arc groove 2036 enables the positioning shaft 2033 to move inside the arc groove 2036, but cannot be relatively displaced forward and backward;

[0042] The first transmission gear 2021 is moved away from the input gear 103 so that the first transmission gear 2021 and the input gear 103 are no longer meshed, and then the input gear 103 rotates to drive the transmission teeth 2035 and the positioning ring plate 2034 to rotate relative to the positioning sleeve 20111, and then the positioning shaft 2033 is pushed through the arc groove 2036, and the arc positioning plate 2037 and the arc cleaning block 2038 are moved away from the center of the positioning block 2031 under the positioning of the limit bar 2039 so that the outer side of the arc cleaning block 2038 coincides with the outer side of the teeth of the transmission teeth 2035, and then the arc cleaning block 2038 rotates in the process of the input gear 103 rotating to drive the transmission teeth 2035 to rotate. It will sink and get stuck into the teeth of the input gear 103, and then the debris inside the input gear 103 will be cleaned by the arc cleaning block 2038. After cleaning, the input gear 103 will rotate in the opposite direction to restore the cleaning assembly 203 to its original position, and then the compressor 2013 will work in the opposite direction to extract the liquid inside the arc sleeve 20231, so that the first transmission gear 2021 returns to its original position and meshes with the input gear 103, and then the servo motor 20113 will rotate so that the circular hole on the outside of the conveying cylinder 2019 and the conveying pipe 20232 are completely staggered, so that the debris between the gaps between the gears can be cleaned, thereby effectively ensuring the service life of the reducer.

[0043] In a preferred embodiment, a limiting groove is opened on the inner side of the positioning block 2031, the shape and size of the limiting groove of the positioning block 2031 match with the arc positioning plate 2037, the width of the arc cleaning block 2038 and the width of the outer positioning groove of the positioning block 2031 match with each other, a limiting groove is opened on the back side of the arc positioning plate 2037, and the tolerance between the limiting groove of the arc positioning plate 2037 and the limiting strip 2039 matches.

[0044] The working principle of the present invention is as follows: during the speed adjustment process, the motor drives the input shaft 102 to rotate, which in turn drives the input gear 103 to rotate, which in turn drives the first transmission gear 2021 to rotate, which in turn drives the positioning sleeve 20111 to rotate through the arc-shaped telescopic mechanism 2023, which in turn drives the connecting circular plate 20114 to rotate, which in turn drives the second transmission gear 204 to rotate, and at the same time drives the conveying cylinder 2019 and the limiting ring 2018 to rotate relative to the connecting tube 2015, and then drives the output gear 105 and the output shaft 104 to rotate through the second transmission gear 204 to complete the speed adjustment, thereby meeting the speed adjustment requirements of the equipment;

[0045] When the output shaft 104 needs to rotate in the opposite direction, the servo motor 20113 first drives the diverter column 20110 and the conveying cylinder 2019 to rotate under the positioning of the connecting pipe 2015, so that the center of the circular hole opened on the outside of the conveying cylinder 2019 is in the same straight line with the center of the circle between the conveying tube 20232, and then the compressor 2013 works to extract the liquid in the hydraulic cylinder 2011 through the backflow pipe 2012 and inject it into the conveying cylinder 2019 through the U-shaped tube 2014 and the connecting pipe 2015, and then under the diversion of the diverter column 20110, the liquid enters the space between the diverter column 20110 and the conveying cylinder 2019, and then when the internal pressure increases, the liquid enters the interior of the arc sleeve 20231 along the circular hole opened on the outside of the conveying cylinder 2019 and the conveying tube 20232, and then pushes the arc limit plate 20234 to a position away from the limit baffle 20233. The position moves and then pushes the arc-shaped telescopic plate 20235 and the first transmission gear 2021 away from the limit baffle 20233, and then makes the two first transmission gears 2021 away from the input gear 103, and then in the process of the reverse rotation of the output shaft 104, only the second transmission gear 204 can be driven to rotate, and the input gear 103 will not be driven to rotate by the first transmission gear 2021 to avoid the reverse rotation of the output shaft 104 driving the motor output shaft to rotate in the reverse direction, resulting in damage to the motor, so that the motor of the reducer can be installed with a one-way motor, resulting in a reduction in the cost of the reducer. After the reverse rotation is completed, the compressor 2013 works in the reverse direction to extract the liquid inside the arc-shaped sleeve 20231, so that the first transmission gear 2021 returns to its original position and meshes with the input gear 103, and then the servo motor 20113 rotates to completely stagger the circular hole opened on the outer side of the conveying cylinder 2019 and the conveying pipe 20232;

[0046] During the long-term operation of the equipment, the above steps make the two first transmission gears 2021 away from the input gear 103 so that the first transmission gear 2021 and the input gear 103 are no longer meshed, and then the input gear 103 rotates to drive the transmission teeth 2035 and the positioning ring plate 2034 to rotate relative to the positioning sleeve 20111, and then the positioning shaft 2033 is pushed through the arc groove 2036, and the arc positioning plate 2037 and the arc cleaning block 2038 are away from the center of the positioning block 2031 under the positioning of the limit bar 2039 so that the outer side of the arc cleaning block 2038 coincides with the outer side of the teeth of the transmission teeth 2035, and then the input gear 103 rotates to drive the transmission teeth 2035 and the positioning ring plate 2034 to rotate relative to the positioning sleeve 20111. During the rotation of the transmission gear 2035, the arc-shaped cleaning block 2038 sinks and gets stuck inside the teeth of the input gear 103. Then, the arc-shaped cleaning block 2038 cleans the debris inside the input gear 103. After the cleaning is completed, the input gear 103 rotates in the opposite direction to restore the cleaning assembly 203 to its original position. Then, the compressor 2013 works in the opposite direction to extract the liquid inside the arc-shaped sleeve 20231, so that the first transmission gear 2021 returns to its original position and meshes with the input gear 103.
