[0002] The cycloid pinwheel reducer is a novel transmission device that applies the planetary transmission principle and adopts cycloid pinwheel meshing. It uses the meshing of the cycloid pinwheel and the internal cylindrical gear to slow down the high-speed rotating input shaft and output a low-speed and high-torque power. The entire transmission device of the cycloid pinwheel reducer can be divided into three parts: input part, reduction part, and output part. It is mainly composed of cycloid pinwheel, internal cylindrical gear, housing, bearings, etc. Cycloid pinwheel reducers are widely used in various types of mechanical equipment and industrial fields, such as petroleum, environmental protection, chemical, cement, transportation, textile, pharmaceutical, food, printing, lifting, mining, metallurgy, construction, power generation and other industries. It is usually used as a drive or reduction device to reduce the motor speed and obtain sufficient torque to drive various equipment.

[0003] At present, cycloid pinwheel reducers can automatically circulate and inject lubricating oil during operation to ensure the lubrication efficiency of the equipment. However, iron filings will be generated in the transmission chamber of the cycloid pinwheel reducer and mixed with the lubricating oil. During the circulation of the lubricating oil, it is easy to cause wear of the transmission gears. In addition, the temperature of the lubricating oil will gradually increase in the transmission chamber. The heat dissipation brought by the circulation is not obvious, and it cannot provide a stable heat dissipation effect for the cycloid pinwheel reducer.

[0004] Therefore, an automatic lubrication device for a cycloid straight-wheel reducer is proposed to solve the above problems. Utility Model Content

[0021] It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0022] like Figures 1-4 As shown, the present application provides an automatic lubrication device for a cycloid straight-wheel reducer, comprising: a cycloid straight-wheel reducer body 1, an oil box 3 for circulating input and output of lubricating oil and a heat dissipation mechanism 4 for quickly dissipating the reflux lubricating oil installed on the outer surface of the cycloid straight-wheel reducer body 1, a filtering mechanism 5 for filtering iron chips from the reflux lubricating oil installed on the top of the heat dissipation mechanism 4, so that the lubricating oil is input into the cycloid straight-wheel reducer body 1 by using the oil box 3, and after the lubricating oil flows back, it enters the filtering structure 5 to filter the iron chips, and then enters the heat dissipation mechanism 4 for rapid heat dissipation, and finally returns to the oil box 3 again and is input into the cycloid straight-wheel reducer body 1, thereby ensuring the heat dissipation efficiency of the lubricating oil to the transmission components, and at the same time being able to filter out iron chips to avoid wear of the transmission components.

[0023] In this embodiment, if Figure 1 and Figure 2As shown, a transmission chamber 22 is installed on the top of the connecting disk 2, and a temperature sensor 23 is embedded on the outer surface of the transmission chamber 22. An oil inlet hole and an oil outlet hole are respectively provided on the outer surface of the transmission chamber 22. An oil pump for conveying lubricating oil is installed inside the oil box 3. The oil pump and the temperature sensor 23 can be linked. When the temperature value detected by the temperature sensor 23 is too high, the oil pump automatically increases the conveying rate. An oil drain pipe 31 is connected to the outer surface of the oil box 3, and one end of the oil drain pipe 31 is connected to the oil inlet hole on the transmission chamber 22. The top of the oil box 3 is connected to the oil inlet pipe 32. Therefore, the lubricating oil delivery rate can be controlled by monitoring the temperature inside the transmission chamber 22, thereby adaptively improving the heat dissipation efficiency.

[0024] In this embodiment, if Figure 1 As shown, a shell 41 is installed on the heat dissipation mechanism 4, and the bottom of the shell 41 is connected to the top of the oil inlet pipe 32, and a mounting ring 51 is installed on the filtering mechanism 5. A filter cartridge 52 is installed at the bottom of the mounting ring 51, and the filter cartridge 52 is located on the top inner side of the shell 41. The top of the mounting ring 51 is threadedly connected to a threaded cover 53, and the top of the threaded cover 53 is connected to an oil return pipe 33. One end of the oil return pipe 33 is connected to the oil outlet hole on the transmission chamber 22, so that the lubricating oil enters the transmission chamber 22 through the oil drain pipe 31. After filling the transmission chamber 22, it enters the filter cartridge 52 through the oil return pipe 33 to filter the lubricating oil. The filtered lubricating oil enters the shell 41, and the lubricating oil in the shell 41 enters the oil box 3 again through the oil inlet pipe 32, thereby forming a circulation path for the lubricating oil.

[0025] In this embodiment, if Figure 2 and Figure 3 As shown, a copper sheet frame 44 is installed inside the shell 41, and heat dissipation fins 45 are installed inside the copper sheet frame 44. A heat dissipation fan 42 is embedded on the outer surface of the shell 41. A circular hole connected to the heat dissipation hole 11 is opened on the back of the shell 41. Therefore, after the lubricating oil enters the copper sheet frame 44, it is dissipated through the heat dissipation fins 45. At the same time, the heat is dissipated by the blowing of the heat dissipation fan 42 and the wind pressure generated by the wind wheel inside the heat dissipation cover of the cycloid straight-wheel reducer is used for exhaust heat dissipation, so that the lubricating oil inside the copper sheet frame 44 can be quickly cooled.

[0026] In this embodiment, if Figure 1 and Figure 4 As shown, a cover plate 46 is sealed on the top of the copper frame 44, an oil return hole 47 is opened on the top of the cover plate 46, the bottom of the filter cartridge 52 coincides with the top edge of the oil return hole 47, and the mounting ring 51 is mounted on the top of the housing 41 by three bolts, so that the lubricating oil filtered by the filter cartridge 52 can enter the copper frame 44 through the oil return hole 47, and the filter cartridge 52 can be disassembled and cleaned.

[0027] In this embodiment, if Figure 3 As shown, a bracket 48 is installed inside the oil return hole 47, a pressure sensor 49 is installed at the center of the bracket 48, and an indicator light 43 is installed on the outer surface of the shell 41. When the pressure of the lubricating oil flowing on the pressure sensor 49 is less than the set value, the indicator light 43 emits a red light alarm. The flow oil pressure of the filtered lubricating oil entering the copper frame 44 is used to determine whether the filter cartridge 52 is congested, so that the filter cartridge 52 can be cleaned in time to ensure the circulation efficiency of the lubricating oil.

[0028] The technical principle of the present utility model is as follows: when the automatic lubrication device of the cycloid straight wheel reducer is used, the lubricating oil is first input into the transmission chamber 22 through the oil drain pipe 31 on the oil box 3. After the lubricating oil fills the transmission chamber 22, it enters the filter cylinder 52 through the oil return pipe 33 to filter the iron chips in the lubricating oil, thereby preventing the iron chips from mixing with the lubricating oil and circulating to cause wear on the transmission components in the transmission chamber 22. The lubricating oil filtered by the filter cylinder 52 can enter the copper frame 44 through the oil return hole 47, and the heat dissipation fins 45 are used for Heat is dissipated by blowing air from the cooling fan 42 and exhausting air to dissipate heat by utilizing the wind pressure generated by the wind wheel inside the heat dissipation cover of the cycloid straight-wheel reducer, so that the lubricating oil inside the copper frame 44 can be quickly cooled down, ensuring that the cycloid straight-wheel reducer operates stably within a suitable temperature range. When the pressure of the lubricating oil flowing on the pressure sensor 49 is less than the set value, the prompt light 43 emits a red light alarm to determine whether the filter cartridge 52 is blocked, so that the filter cartridge 52 can be cleaned in time to ensure the circulation efficiency of the lubricating oil.
