[0002] Reducers are generally used for low-speed and high-torque transmission equipment, including input shafts and output shafts. The output shaft of an electric motor, internal combustion engine or other high-speed power source is fixed to the input shaft of the reducer. At this time, the rotating output shaft of the reducer transmits the torque through the gear with fewer teeth in the box to mesh with the large gear on the output shaft to achieve the purpose of deceleration.

[0003] However, during the operation of the reducer, a large amount of heat energy will be generated due to the friction between internal gears, bearings and other components and the stirring of the oil. If this heat cannot be effectively removed, it will cause the temperature of the reducer housing to rise, which will in turn cause the internal lubricating oil to age faster due to high temperature, and the aging of sealing materials will increase internal friction, which will affect the use of the reducer.

[0028] 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.

[0029] like Figure 1-Figure 5As shown, the utility model discloses a speed reducer that is convenient for heat dissipation, which is composed of a housing 1, an input shaft 22 located on the left side of the housing 1, an output shaft 33 on the right side, and a transmission mechanism (which is a prior art and is not shown in the figure). The transmission mechanism is located in the housing 1 and the transmission mechanism links the input shaft 22 and the output shaft 33. After the motor 7 is fixed to the input shaft 22, the motor 7 is started at this time, and the torque of the motor 7 can be transmitted to the input shaft 22 located on the housing 1 through the motor output shaft 71. The input shaft 22 transmits the torque to the linkage mechanism, and the linkage mechanism is usually a gear The input shaft 22 will first transmit the torque to the small gear with a small number of gears, and then the small gear will mesh with the large gear with a large number of gears to reduce the speed. Usually, the speed of the large gear will be directly transmitted to the output shaft 33. Therefore, compared with the input shaft 22, the speed of the output shaft 33 is reduced, that is, the torque output by the motor 7 is decelerated. It also includes a cooling pipe 44 filled with condensate. The housing 1 includes a left mounting portion 11, a right mounting portion 12, and a matching portion 13 located between the left mounting portion 11 and the right mounting portion 12. The cooling pipe 44 is arranged in a circuitous manner with multiple turns and The left side of the cooling pipe 44 is sleeved on the outside of the matching portion 13, and the right side is against the left mounting portion 11, and the right side is against the right mounting portion 12. The left mounting portion 11 and the matching portion 13 are detachably connected by bolts or the like, and the matching portion 13 and the right mounting portion 12 are detachably connected by bolts or the like. 1. Since the left mounting portion 11 and the matching portion 13 are detachably connected, and the matching portion 13 and the right mounting portion 12 are detachably connected, after the left mounting portion 11 is removed from the matching portion 13 or the right mounting portion 12 is removed from the matching portion 13, the cooling pipe 44 is installed. After being inserted into the mating part 13, the removed left mounting part 11 or right mounting part 12 is installed back onto the mating part 13, so that the cooling pipe 44 can be stably located on the mating part 13, so that the cooling pipe 44 can fit the circumference of the mating part 13 so that the temperature of the coolant can be transferred to the mating part 13 through the cooling pipe 44 to achieve cooling of the reducer in the working state; 2. Since the cooling pipe 44 is arranged in a circuitous manner with multiple turns, the length of the cooling pipe 44 and the contact area with the mating part 13 are increased, thereby further improving the cooling effect on the mating part 13.

[0030] Among them, the shell 1 also includes a connecting part 14, and the front and rear sides of the connecting part 14 are detachably connected to the left mounting part 11 and the right mounting part 12 respectively by bolts, snaps, etc., and the cooling pipe 44 includes a positioning section 41, and the positioning section 41 is located in the connecting part 14. Since the positioning section 41 is located in the connecting part 14 and the left and right sides of the connecting part 14 are detachably connected to the left mounting part 11 and the right mounting part 12 respectively, the connecting part 14 can support the positioning section 41 of the cooling pipe 44 and the detachable connection between the connecting part 14 and the left mounting part 11 and the right mounting part further improves the connection stability between the left mounting part 11, the right mounting part 12 and the matching part 13.

[0031] Preferably, a lower magnet 411 is provided at the bottom of the positioning section 41, and an upper magnet 141 that engages with the lower magnet 411 is provided on the connecting portion 14. Since the lower magnet 411 at the bottom of the positioning section 41 located in the connecting portion 14 will engage with the upper magnet 141 on the connecting portion 14, after the cooling tube 44 is installed on the matching portion 13, except that the left and right sides of the cooling tube 44 will be limited by the left mounting portion 11 and the right mounting portion 12 respectively and will not move in the left and right directions, the lower magnet 411 of the positioning section 41 will engage with the upper magnet 141 so that the cooling tube 44 will not shake in the up and down directions after being located on the matching portion 13, thereby enabling the cooling tube 44 to be more stably located on the matching portion 13.

[0032] Preferably, the connecting portion 14 is provided with a left mounting block 142 protruding toward the left, and the connecting portion 14 is provided with a right mounting block 143 protruding toward the right, the left mounting portion 11 is provided with a left mounting slot 111 corresponding to the left mounting block 142, and the right mounting portion 12 is provided with a right mounting slot 121 corresponding to the right mounting block 143. Since the left mounting block 142 of the connecting portion 14 will be inserted into the left mounting slot 111 of the left mounting portion 11 and the right mounting block 143 can be inserted into the right mounting slot 121 of the right mounting portion 12, and the lower magnet 411 of the positioning section 41 can be attracted with the upper magnet 141 of the connecting portion 14 to realize the relative positioning of the left mounting portion 11, the right mounting portion 12 and the matching portion 13, thereby providing convenience for the detachable connection of the left mounting portion 11, the right mounting portion 12 and the matching portion 13.

[0033] In addition, the cooling pipe 44 includes a plurality of mounting sections 42, each of which is arranged on the matching portion 13 at intervals along the circumferential direction, and each of the mounting sections 42 is detachably connected to the matching portion 13 by means of magnetism, Velcro, etc. Since each mounting portion is detachable from the matching portion 13, after the cooling pipe 44 is installed on the matching portion 13, the left and right sides of the cooling pipe 44 are respectively abutted against the left mounting portion 11 and the right mounting portion 12, and the positioning section 41 is located outside the connecting portion 14. The mounting section 42 can be stably located on the matching portion 13, thereby further improving the connection relationship between the cooling pipe 44 and the matching portion 13.

[0034] It also includes a plurality of heat dissipation ribs 5 fixedly installed on the matching part 13 by welding or the like, and each heat dissipation rib 5 is respectively located between adjacent mounting sections 42. The main function of the heat dissipation rib 5 is to increase the surface area, thereby improving the heat exchange efficiency. The heat dissipation rib 5 forms a plurality of thin sheets or ribs on its surface, which significantly increases the surface area in contact with the surrounding air, allowing more heat to be conducted from the heat source of the equipment to the heat dissipation rib 5, and then dissipated from the heat dissipation rib 5 to the air. The heat dissipation rib 5 can disperse the heat concentrated at one point to a larger area, thereby preventing local overheating and protecting sensitive components from damage. In addition, since each heat dissipation rib 5 is located between adjacent mounting sections 42, the cooling pipe 44 located on the matching part 13 will not move in the left and right directions.

[0035] In addition, it also includes a cover body 6, and the cooling tube 44 also includes a liquid injection port 43 at the top left side. The shape and size of the cover body 6 are adapted to the liquid injection port 43 and the cover body 6 is detachably connected to the cooling tube 44 by means of bolts, snaps, etc. Since the shape and size of the cover body 6 are adapted to the liquid injection port 43 and the cover body 6 is detachable from the cooling tube 44, when the coolant in the cooling tube 44 fails, the cover body 6 on the cooling tube 44 is removed from the cooling tube 44, and the coolant in the cooling tube 44 can be poured out and new coolant can be refilled, and then the cover body 6 is installed, so that the cooling tube 44 can further play a role in cooling and dissipating heat for the matching part 13.

[0036] Preferably, the cooling tube 44 is provided with a plurality of disassembly parts 44 protruding from the liquid injection port 43, each disassembly part 44 is made of a material that is easy to deform, such as rubber, and includes a limiting section 441 at the bottom, each limiting section 441 is against the cover body 6, and after the cover body 6 is installed on the cooling tube 44, each limiting section 441 will be forcibly inserted into the cover body 6 and will be against the bottom of the cover body 6, so that the cover body 6 is stably located on the cooling tube 44. When the cover body 6 needs to be removed from the cooling tube 44, the limiting section 441 is bent so that it can pass through the cover body 6 more smoothly and be separated from it, thereby realizing the disassembly of the cover body 6.

[0037] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
