Description

Technical Field

[0001] The present invention relates to the technical field of reduction motors, and in particular to a reduction motor capable of being quickly disassembled and installed, and a use method thereof. Background Art

[0002] A reduction motor is an integration of a reducer and an electric motor. This integration is also commonly called a gear motor or gear motor.

[0003] Usually, professional reducer manufacturers integrate and assemble them and supply them as a complete set. Reducer motors are widely used in the steel industry, machinery industry, etc. The advantages of using reducer motors are simplified design and space saving. With the continuous development of the reducer motor industry, more and more industries and enterprises have used reducer motors, and a number of enterprises have entered the reducer motor industry.

[0004] In particular, metallurgy, electric power, construction machinery, building materials, power, etc. have accelerated development, so the demand for DC reduction motors has gradually expanded. With the focus on the machinery manufacturing industry, the entire industry will continue to maintain a rapid development trend, especially the growth of gear DC reduction motors will be greatly improved.

[0005] The main functions of the reduction motor are: increasing the output torque and reducing the inertia of the load while reducing the speed. The torque output ratio should be calculated by multiplying the motor output by the reduction ratio. The output torque cannot exceed the rated torque specified on the reduction motor. The reduced inertia is the square of the reduction ratio.

[0006] Gear motors are generally used in low-speed and high-torque transmission equipment. The power of electric motors, internal combustion engines or other high-speed running engines is decelerated by meshing the gear with fewer teeth on the input shaft of the gear motor with the large gear on the output shaft. Ordinary gear motors also have several pairs of gears with the same principle to achieve the ideal deceleration effect, and the ratio of the number of teeth of the large and small gears is the transmission ratio.

[0007] The biggest feature of the worm gear reduction motor is that it has a reverse self-locking function, can have a larger reduction ratio, and the input shaft and the output shaft are not on the same axis, nor on the same plane. However, the general worm gear reduction motor is relatively large in size, with low transmission efficiency and low precision. The harmonic transmission of the harmonic reduction motor uses the controllable elastic deformation of the flexible element to transmit motion and power. It is not large in size and has high precision, but the disadvantages are that the flexible wheel has a limited life, is not impact-resistant, and has poor rigidity compared to metal parts. The characteristics of the planetary reduction motor are a relatively compact structure, a small return clearance, high precision, a long service life, and a large rated output torque, but the price of the planetary reduction motor is relatively expensive.

[0008] For example, the application number 202221117662.3 discloses a reduction motor that can be quickly disassembled, including a reduction motor, a disassembly frame is slidably installed at one end of the reduction motor, a reducer is fixedly connected to one end face of the reduction motor, disassembly threaded holes are evenly provided on the side edges of the reducer, a sealing gasket is fixedly connected to the side center edge of the reducer, a limiting hole is provided at the center of one end face of the reduction motor, a support frame is welded to the edge of one end face of the reduction motor, a second sleeve hole is symmetrically provided on the edge of one end face of the reduction motor, and a first limiting hole is symmetrically provided on the edge of the other end face of the reduction motor. The utility model can facilitate the rapid disassembly of the reduction motor during maintenance by installing a disassembly frame at one end of the reduction motor, thereby improving the work efficiency of disassembling the reduction motor, avoiding impact on the gap between the reduction motor and the reducer, and effectively protecting the outer surface of the reduction motor.

[0009] However, most of the current reduction motors have problems such as great difficulty and high processing cost in ensuring coaxiality, difficulty in installing the motor shaft, low assembly precision, difficulty in disassembling the reduction motor, easy damage to the connecting end cover during disassembly of the reduction motor, easy overheating of the reduction motor, and poor heat dissipation. Summary of the invention

[0010] The technical problem to be solved by the present invention is to reduce the processing difficulty and cost while ensuring coaxiality, improve the motor shaft installation method, improve the assembly accuracy, reduce the difficulty of disassembling the reduction motor, reduce the frequency of damage to the connecting end cover during the disassembly of the reduction motor, reduce the heating of the reduction motor, and improve the heat dissipation effect of the reduction motor.

Preferably, the quick-release tensioning mechanism comprises an oblique cone tensioning ring and a quick-release end cover, the oblique cone tensioning ring and the quick-release end cover are fixedly connected along the axial direction, a plurality of groups of fixed countersunk holes are evenly arranged on the end surface of the quick-release end cover, and a plurality of groups of removal top screw holes are arranged on the same pitch circle, a tensioning variable groove is opened on the outer side surface of the oblique cone tensioning ring, and a fastening shaft hole is opened on the oblique cone tensioning ring and the quick-release end cover along the axial direction thereof; the quick-release tensioning mechanism is fixedly arranged on the end of the turbine shaft through the fixed countersunk holes on the quick-release end cover; Preferably, the embedded cooling mechanism includes an elastic steel ring and a cooling copper tube; the elastic steel ring is provided with two groups, which are coaxially sleeved together, and the cooling copper tube is provided with multiple groups, which are fixedly arranged between the two groups of elastic steel rings.

The inlet pipe is connected to the first-stage cooling pipe, the outlet pipe is connected to the last-stage cooling pipe, and the inlet water distribution pipe is connected to the cooling water pipe, the first-stage cooling pipe, and one end of the last-stage cooling pipe , the return water manifold is connected to the cooling water pipe and one end of the final cooling pipe, the embedded cooling mechanism is fixedly arranged on the inner wall of the reducer housing, the reducer housing is provided with a cooling water inlet hole and a cooling water outlet hole, the water inlet pipe passes through the cooling water inlet hole to connect to the external joint, the water outlet pipe passes through the cooling water outlet hole to connect to the external joint, the external joint is fixedly connected to the cooling water inlet hole and the cooling water outlet hole, the upper end surface of the reducer housing is provided with a lubricating oil hole, and the outer shell of the reducer housing is provided with a plurality of groups of fin-type groove ribs; A method for using a reduction motor that can be quickly disassembled and installed comprises the following steps: S1. When installing the reduction motor, the outer ring of one group of worm bearings is close to the worm bearing shoulder, and the inner ring is close to the worm bearing retaining ring, and the inner ring of the other group of worm bearings is restricted in freedom by the other group of worm bearing retaining rings, thereby restricting the freedom of the driving worm relative to the reduction gear housing in the direction of the axis of the worm shaft hole, while maintaining its axial rotation and avoiding axial movement; S2, the end cover hole and the turbine shaft end cover limit the freedom of the outer ring of the turbine bearing, and the turbine bearing spacer ring limits the freedom of the inner ring of the turbine bearing, thereby limiting the freedom of the turbine shaft relative to the reducer housing in the axial direction of the turbine shaft hole, while maintaining its axial rotation and avoiding axial movement; S3, the reduction motor rotates, and drives the driving worm to rotate through its shaft end, and drives the turbine shaft to rotate through the meshing transmission between the driving worm and the reduction turbine fixedly arranged on the turbine shaft, thereby realizing the reduction motion; S4. When installing the motor, the shaft end of the reduction motor is transitionally matched with the shaft positioning hole, and the positioning magnetic mouth groove is interference-fitted with the positioning magnetic mouth boss; use an external hexagonal screw to apply force diagonally until the positioning magnetic mouth groove is completely aligned with the positioning magnetic mouth boss. When the reduction motor needs to be removed, loosen the external hexagonal screw, screw in multiple sets of set screws along the motor withdrawal hole, and apply force diagonally and symmetrically alternately, so that the positioning magnetic mouth boss is separated from the positioning magnetic mouth groove, and the shaft end of the reduction motor is separated from the shaft positioning hole; S5, the external shaft is transitionally matched with the output shaft connecting hole, and the shaft end thereof extends into the fastening shaft hole. The fixed countersunk hole on the quick-release end cover is fixedly arranged at the end of the turbine shaft. Under the pulling force of the fixing screw, the oblique cone tensioning ring moves along the axis of the oblique cone shaft hole, causing the tensioning variable groove to shrink, and the fastening shaft hole positions and locks the external shaft; when the reducer needs to be removed, the fixing screws are removed, and multiple sets of set screws are symmetrically screwed in along the removal top screw holes, and the force is applied diagonally and symmetrically alternately, so that the oblique cone tensioning ring moves along the oblique cone shaft hole toward the outer axis, the tensioning variable groove is relaxed, and the fastening shaft hole is separated from the external shaft, thereby separating the reduction motor body from the external shaft; S6, cooling water enters the first cooling pipe through the water inlet pipe, then enters the water inlet pipe, and then enters the cooling water pipe, and is collected and enters the return water pipe, and then flows into the water outlet pipe through the last cooling pipe and then flows out of the reduction motor; Compared with the prior art, the present invention has the following beneficial effects: 1. By setting the worm shaft hole and adopting a through-hole design, the bearing mounting holes at both ends can be processed in one go, which improves the coaxiality of the worm bearings at both ends while reducing the processing difficulty, time and cost. The retaining ring is used to limit the bearing freedom, which ensures the assembly accuracy while reducing the complexity of the structure and the material cost. The end cover hole is designed in the turbine shaft hole to reduce the assembly difficulty and the processing difficulty. The turbine shaft hole and the worm shaft hole can be clamped in one go, which improves the positional accuracy and geometric accuracy between the two, improves the assembly accuracy of the reduction motor and increases the service life of the reduction gear.

[0013] 2. By setting the shaft positioning hole, the broken guide groove and the broken guide groove angle, while the shaft positioning hole ensures the matching accuracy with the motor shaft end, the design of the broken guide groove and the broken guide groove angle reduces the difficulty of installing the motor shaft due to over-fitting, which not only ensures the assembly accuracy but also reduces the assembly difficulty.

[0014] 3. By setting the motor fixing hole and motor withdrawal hole on the multi-functional connection end cover, when removing the motor from the reducer, the motor shaft end can be safely and conveniently removed from the reducer hole by using the set screws on the motor withdrawal holes symmetrically set at the four corners to apply force evenly diagonally, thereby reducing the difficulty of disassembling the reducer motor.

[0015] 4. By setting the inner and outer ribs on the multifunctional connection end cover, the inner and outer ribs are arranged in a staggered manner, which effectively improves the structural rigidity of the multifunctional connection end cover while ensuring heat dissipation, and prevents damage to the connection end cover during the disassembly of the reducer.

[0016] 5. By providing heat dissipation holes on the multifunctional connection end cover and installing a silencer thereon, the heat inside the motor is cooled by the cooling fan. During the rotation of the motor shaft, the air inside the multifunctional connection end cover rotates with it and is discharged through the heat dissipation holes for rapid heat dissipation. By adding a silencer, the noise is reduced and external dust is prevented from entering the vicinity of the motor shaft through the heat dissipation holes.

[0017] 6. By setting a petal-type turbine fixing boss, the structural rigidity of the turbine and the turbine shaft is improved compared to the conventional key connection, and the torsional bearing limit of the turbine shaft is improved.

[0018] 7. By setting up a quick-release tensioning mechanism, when the external input shaft is connected to the output shaft connecting hole of the reduction motor, the interference of the output shaft connecting hole is reduced, and the external input shaft is locked by the quick-release tensioning mechanism, and the coaxial positioning and key connection transmission ensure the positioning accuracy and torque transmission, while reducing the difficulty of disassembling the reduction motor from the external output shaft. The quick-release tensioning mechanism can be ejected by removing the top screw. Since the interference of the output shaft connecting hole is reduced, it is much easier to remove the external input shaft from the output shaft connecting hole.

[0019] 8. By setting up an embedded cooling mechanism and embedding the cooling system inside the reduction motor, the heat generating components are directly cooled, thus avoiding the thermal resistance limitation of the thermal interface material layer in the traditional cooling method, thereby improving the heat dissipation efficiency. In addition, embedded cooling can also realize the compact design of the equipment, save space, and make the appearance of the equipment more beautiful. BRIEF DESCRIPTION OF THE DRAWINGS
