Description

Technical Field

[0001] The utility model relates to the technical field of worm gear reducers, in particular to a worm gear reducer which is beneficial to heat dissipation. Background Art

[0002] Worm gear reducer is a power transmission mechanism that uses a gear speed converter to reduce the number of revolutions of the motor to the desired number of revolutions and obtain a larger torque. In the mechanism used to transmit power and motion, the application range of reducers is quite wide. It can be seen in the transmission systems of various machines, from ships, cars, locomotives, heavy machinery and tools used in construction, processing machinery and automated production equipment used in the machinery industry, to common household appliances and clocks in daily life. Its application ranges from large power transmission work to small loads and precise angle transmission. In industrial applications, reducers have the function of reducing speed and increasing torque. Therefore, they are widely used in speed and torque conversion equipment.

[0003] In the prior art, existing worm gear reducers generally use non-ferrous metals for worm wheels and harder steel for worms. Since the worm wheels and worms are intertwined in space and transmission and deceleration are performed through friction, the temperature at the meshing point of the worm wheel and the worm will rise sharply after long-term use, and the heat is dissipated through conduction through the body, which is a passive heat dissipation method. If the heat dissipation operation is not performed in time, it is easy to cause differences in thermal expansion between the various parts and seals of the reducer and cause damage, thereby affecting the normal operation of the reducer, thereby shortening the service life of the reducer.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-4 The utility model discloses a worm gear reducer which is conducive to heat dissipation, comprising a reducer structure 1, wherein the outer wall of the reducer structure 1 is provided with a heat dissipation mechanism 2 and a pre-processing structure 3, wherein the pre-processing structure 3 is located above the heat dissipation mechanism 2;

[0022] The reducer structure 1 includes a housing 4, wherein a worm wheel body 7 and a worm body 8 are rotatably connected inside the housing 4, wherein the worm wheel body 7 and the worm body 8 are meshed and driven, and a driving motor 5 is fixedly mounted on the outer wall of the housing 4, wherein the output shaft of the driving motor 5 is fixedly connected to the end of the worm body 8;

[0023] The heat dissipation mechanism 2 includes heat dissipation fins 11 and a heat dissipation fan 12. A mounting recess 10 is provided on the inner wall of the housing 4. The mounting recess 10 is located obliquely above the meshing point of the worm wheel body 7 and the worm body 8. The heat dissipation fins 11 are located on one side of the mounting recess 10 close to the meshing point of the worm wheel body 7 and the worm body 8. The heat dissipation fan 12 is located inside the mounting recess 10. A dustproof net 13 is movably clamped on the outer side of the mounting recess 10.

[0024] By setting up the heat dissipation mechanism 2, the heat generated by the meshing of the worm wheel body 7 and the worm body 8 can be absorbed by the heat dissipation fins 11, and then the heat on the heat dissipation fins 11 is dissipated by the heat dissipation fan 12, thereby reducing the temperature inside the casing 4, facilitating the heat dissipation and heat dissipation effect when the casing 4 is operated, avoiding the situation where parts are damaged due to excessive heat and thus affecting the normal operation of the reducer, which is beneficial to the continuous use of the reducer and can effectively extend the service life of the reducer.

[0025] Specifically, one end of the worm wheel body 7 and the worm body 8 away from the inner wall of the housing 4 is fixedly connected with a conveying roller 6 , and the conveying roller 6 extends to the outside of the housing 4 through an extension opening 9 .

[0026] In this embodiment, the worm wheel body 7 and the worm body 8 can be quickly connected to other parts by using the conveying roller 6 .

[0027] Specifically, the pretreatment structure 3 includes an electric push rod 15, a driving groove 14 is opened on the outer wall of the casing 4, a bending rod 16 is fixedly installed on the movable end of the electric push rod 15, the other end of the bending rod 16 extends to the outside of the driving groove 14 and is fixedly installed with a baffle plate 17, the baffle plate 17 is located above the dustproof net 13, and bristles are provided on the side of the baffle plate 17 close to the casing 4.

[0028] In this embodiment, by setting up a pretreatment structure 3, the electric push rod 15 can drive the baffle plate 17 to move up and down on the outside of the dustproof net 13, so that the bristles arranged on the back side of the baffle plate 17 can remove the dust accumulated on the dustproof net 13, thereby ensuring the air flow of the dustproof net 13, and when the reducer is not in use, the dustproof net 13 can be shielded by the baffle plate 17, thereby further improving the dustproof effect.

[0029] When in use, the reducer is first placed at a designated position, and then the conveying roller 6 is connected to other parts, and then the driving motor 5 is started, so that the driving motor 5 drives the worm body 8 to rotate, so that the worm body 8 drives the worm wheel body 7 to rotate through meshing transmission, and then the worm body 8 and the worm wheel body 7 drive the two conveying rollers 6 to rotate, so that the conveying roller 6 drives other parts to rotate;

[0030] When the inside of the housing 4 needs to be cooled, the cooling fan 12 is started, so that the cooling fan 12 starts to run. At this time, the cooling fan 12 can draw the air inside the housing 4 outward. Since the cooling fins 11 can absorb the heat generated at the meshing point of the worm wheel body 7 and the worm body 8, the cooling fan 12 can extract the heat from the cooling fins 11, thereby reducing the temperature inside the housing 4.

[0031] When the dust screen 13 needs to be cleaned, the electric push rod 15 is started, so that the electric push rod 15 can drive the baffle plate 17 to move up and down on the outside of the dust screen 13, so that the bristles arranged on the back side of the baffle plate 17 can remove the dust accumulated on the dust screen 13.
