Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of reduction motors, in particular to an integrated worm gear box reduction motor. Background Art
[0002] A reduction motor refers to an integration of a reducer and a motor. This integration is also commonly called a gear motor or gear motor. It is usually integrated and assembled by a professional reducer manufacturer and supplied as a set with the motor. The reducer can be divided into planetary gear reduction, bevel gear reduction, worm gear reduction, etc.
[0003] The worm gear reduction motor uses a worm gear reduction. The worm gear is arranged in the worm gear box, and the power drive is realized by fixing the worm gear and the motor output shaft. The worm gear in the worm gear box adopts an oil seal, which will generate a lot of heat during operation, and the oil temperature will continue to rise. Excessive oil temperature will cause oil failure, thereby increasing the frequency of oil change. At the same time, excessive oil temperature will also accelerate the aging of rubber sealing components. The existing worm gear box heat dissipation can only be dissipated through the heat sink fixed to the worm gear box body, and the heat dissipation effect is not good. For this reason, we propose an integrated worm gear reduction motor. Utility Model Content

[0006] Preferably, multiple heat dissipation pipes are provided and symmetrically distributed on the outside of the worm gear box body.

[0008] Preferably, an oil inlet is fixed on the top of the worm gear box body, and the top of the oil inlet is higher than the top of the heat dissipation pipe to avoid excessive oiling.
[0009] Preferably, the heat dissipation pipe is made of copper alloy, which has a better heat dissipation effect.
[0010] Preferably, a plurality of heat dissipation fins are evenly fixed on the outside of the heat dissipation pipe to increase the heat exchange area between the inside of the heat dissipation pipe and the external air.

[0014] Compared with the traditional technology, the beneficial effects of the utility model are:
[0015] 1. A plurality of heat dissipation pipes are fixed on the outside of the worm gear box body, and the bottom of the heat dissipation pipe is located below the side of the worm gear box body, so that the oil and gas in the worm gear box body can enter the lower and upper parts of the heat dissipation pipes respectively, providing a larger heat exchange area for the heat exchange between the hot oil, hot gas and the external air, and realizing the rapid dissipation of the heat inside the worm gear box body.
[0016] 2. Evenly arranging heat dissipation fins on the outside of the heat dissipation pipe can further increase the heat exchange area between the inside of the heat dissipation pipe and the outside air.

[0024] See also Figure 1-Figure 4 The figure shows an integrated worm gear box reduction motor, which relates to the technical field of reduction motors, including a worm gear box body 1 and a motor body 2. The worm gear box body 1 and the motor body 2 are fixed together by bolts, and the worm of the worm gear box body 1 and the output shaft of the motor body 2 are fixed. The worm gear box body 1 is provided with a heat dissipation component 3 for dissipating the heat of the worm gear box body 1. The heat dissipation component 3 includes a heat dissipation pipe 4, which is arranged on the worm gear box body 1. A cold water pipe 10 connected to an external water tank at both ends is fixed in the heat dissipation pipe 4.

The portion of the cold water pipe 10 located inside the heat dissipation pipe 4 is spiral.
[0025] Some implementation methods of the present application are described in detail below with reference to the accompanying drawings:
[0026] See also Figure 1-Figure 4 By arranging a heat dissipation pipe 4 on the worm gear box body 1 so that the internal oil can overflow to the outside of the worm gear box body 1, the oil entering the heat dissipation pipe 4 is in contact with more external air, so that the cooling effect of the oil is better. At the same time, the hot air above the inside of the worm gear box body 1 can also enter the heat dissipation pipe 4 to dissipate heat, thereby further reducing the temperature inside the worm gear box body 1.
[0027] Among them, there are multiple heat dissipation pipes 4, which are symmetrically distributed on the outside of the worm gear box body 1. Both ends of the heat dissipation pipes 4 are connected to the inside of the worm gear box body 1. The upper end of the heat dissipation pipe 4 is fixed on the top of the worm gear box body 1, and the lower end is fixed on the lower side of the worm gear box body 1, so that the oil in the worm gear box body 1 can enter the heat dissipation pipe 4 to improve the heat dissipation effect of the oil. The top and surrounding areas of the worm gear box body 1 are provided with sink grooves 8, and evenly distributed auxiliary heat sinks 9 are fixed in the sink grooves 8 to improve the heat dissipation effect of the worm gear box body 1.
[0028] Meanwhile, the heat dissipation pipe 4 is made of copper alloy, which has a better heat dissipation effect.
[0029] It is worth noting that an embedding groove 7 is provided on the outer side of the top of the worm gear box body 1, and the heat pipe 4 equipped with heat dissipation fins 6 is embedded in the embedding groove 7, which can assist in fixing the side of the heat pipe 4 and reduce the impact of the vibration when the motor is working. An oil inlet 5 is fixed on the top of the worm gear box body 1, and the top of the oil inlet 5 is higher than the top of the heat pipe 4, which can avoid excessive refueling.
[0030] A plurality of heat dissipation pipes 4 are fixed on the outside of the worm gear box body 1, and the bottom of the heat dissipation pipe 4 is located below the side of the worm gear box body 1, so that the oil and gas in the worm gear box body can enter the lower part and the upper part of the heat dissipation pipe 4 respectively, providing a larger heat exchange area for the heat exchange between hot oil, hot gas and external air, so as to realize the rapid dissipation of the heat inside the worm gear box body 1, and at the same time, the cold water pipe 10 fixed in the heat dissipation pipe 4 is used to pass the external cold water into the heat dissipation pipe 4, and the spiral cold water pipe 10 can increase the heat transfer time between the water in the cold water pipe 10 and the hot gas and hot oil in the heat dissipation pipe 4, and the cold water flowing in the cold water pipe 10 takes away part of the heat in the heat dissipation pipe 4, so as to further improve the heat dissipation effect.
[0031] See also Figure 1 and Figure 3 In this embodiment, both ends of the heat dissipation pipe 4 are fixed to the worm gear box body 1 by bolts, which is convenient for disassembly and cleaning. A plurality of heat dissipation fins 6 are evenly fixed on the outside of the heat dissipation pipe 4. The heat inside the heat dissipation pipe 4 contacts with the external air through the heat dissipation fins 6, which can further increase the heat exchange area between the inside of the heat dissipation pipe 4 and the external air, thereby improving the heat dissipation effect.
