- Reduction gearbox
- the invention also solves the technical problems of poor sealing performance and high manufacturing cost of the existing motor reduction gear box, and provides a motor reduction gear box with good sealing performance and low manufacturing cost.
- a motor reduction gear box includes a gear box box body, an end cover that cooperates with the box body, and a gear reduction mechanism placed inside the box body, which is characterized in that A groove is provided on the inner surface of the cover, and a receiving hole is provided on the bottom surface of the cover. A corresponding receiving hole is provided on the box body. Both ends of the gear drive shafts of the various levels are fixed to the box body and the end cover.
- the gear box of the utility model shares the same end cover with the motor, and both ends of the gear transmission mechanism of each level are pivoted into the accommodation holes through bearings, shaft sleeves or similar parts.
- the utility model greatly simplifies the structure of the whole machine, and makes the The assembly is simpler and more convenient. At the same time, this structure is also conducive to controlling the sealing performance and running performance of the whole machine.
- a flange is provided around the accommodating hole on the bottom surface of the box body, an inner bottom end is provided with a stop, and a bearing is built in the flange.
- the provision of the flange saves material and reduces processing area on the one hand, and makes the bottom thickness of the box body of the gear box substantially the same, preventing cracks caused by thermal expansion and contraction.
- a flange is provided around the through-hole of the output shaft of the motor reduction gear box, and a stop is provided therein, and the bottom surface of the stop is higher than the bottom surface of the box body.
- the setting of the flange can also save materials and reduce the processing area.
- a boss is formed on the bottom surface of the box, which reduces the box. The thickness of the bottom surface also reduces the height of the box and saves material.
- the output shaft of the motor reduction gear box is pivotally connected to the box body through a bearing, and an oil seal is provided on the stop of the output shaft through hole, and the height of the flange is 2.0-5.0 mm, and The height of the mouth is 0.5-2. 0mm, and the closed chamber of the gear box is cylindrical.
- Such a structure can reduce the leakage of the lubricating oil of the gear in the gear box, improve the sealing performance, and make the output shaft bearing always well lubricated.
- a sealing ring is provided between the box body and the end cover of the motor reduction gear box; four corners of the box body are respectively provided with fixed threaded holes, and the end cover is provided with a corresponding one Through-hole, both Secure with screws.
- the setting of the sealing ring prevents the leakage of lubricating oil between the motor and the end cover, thereby improving the sealing performance.
- the end cover and the box are fixed by screws, because the screws do not pass through the sealing cavity, so The leakage of lubricating oil in the gap of the screw hole is avoided, so the sealing performance of the whole machine is further improved.
- the motor is provided with a through hole, and a corresponding fixing screw hole is provided at the lower part of the end cover, and the two are also fixed by screws.
- the drive shafts of the various stages of the reduction mechanism of the motor reduction gear box are arranged in parallel; the diameters of the end cover and the box body are substantially equal.
- the gear reduction mechanism of the motor reduction gear box is a four-stage gear reduction mechanism
- the flange encloses four accommodation holes pivotally connected to the two ends of the four-stage gear transmission rod, which has a good reduction effect.
- the invention has the characteristics of compact structure, more convenient manufacturing and assembly, material saving, low manufacturing cost, and good sealing performance of the whole machine, and is a motor reduction gear box with wide application prospects.
- FIG. 1 is a schematic structural diagram of a motor reduction gear box of the present invention
- FIG. 2 is a schematic structural view of a front cover of a motor reduction gear box cover of the present invention
- FIG. 3 is a schematic rear structural view of an end cover of a motor reduction gearbox of the present invention.
- Fig. 4 is a cross-sectional view of the end cover of the motor reduction gearbox of the present invention.
- a motor reduction gear box includes a motor 13, a reduction box body 1, an end cover 9, and a gear reduction mechanism 3.
- the gear reduction mechanism 3 is a four-stage gear reduction mechanism, which is arranged in a sealed cavity between the reduction gear box 1 and an end cover 9, and a groove 37 is provided on the inner surface of the end cover.
- Four accommodating holes 38 are provided on the bottom surface thereof, and the accommodating holes 31 corresponding to the accommodating holes 31 are provided on the box 1.
- the four-stage gear reduction mechanism 3 has a standard structure.
- Each stage of the transmission component is composed of a transmission shaft, an input gear, and an output gear. The input gear of the first stage meshes with the output gear of the previous stage, and the output gear of the first stage is connected to the next stage.
- the input gears of the stage are meshed, and the upper and lower ends of the transmission shaft are fixed in the receiving holes 31 and 38 on the box 1 and the end cover 9 through bearings.
- An input gear 6 of a first transmission member thereof meshes with a motor drive shaft 12.
- the box 1 and the end cover 9 are processed by CNC precision machining equipment, and correspondingly, receiving holes 31 are provided, and a flange 32 and a stop 34 are provided around the receiving hole 31.
- the accommodating hole on the end cover 9 is not shown, and should be opposite to the accommodating hole provided on the box 1 to ensure the verticality of the stepless drive shaft), the accommodating hole adopts a blind hole structure, and the deceleration
- the bearings on the drive shafts of the various stages of the mechanism 3 are installed in the corresponding accommodation holes.
- the output shaft through-hole 36 of the reduction gear box is provided with a flange 33 and a shaft outlet opening 21.
