Description

Technical Field

[0001] This utility model relates to the field of gear reducer technology, specifically an energy-saving high-ratio hardened tooth surface gear reducer. Background Technology

[0002] High-ratio hardened gear reducers are commonly used transmission devices in industrial fields. They can achieve high-ratio transmission, reducing the high speed of the input shaft to the required low speed while increasing the output torque. This meets the needs of different equipment for high-ratio transmission and can be widely used in applications requiring low-speed, high-torque output. In addition, they have high load-bearing capacity. The gears are made of high-strength, low-carbon alloy steel through carburizing and quenching, resulting in high tooth surface hardness, good wear resistance, and the ability to withstand large loads, making them suitable for heavy-duty working conditions.

[0003] The existing high-ratio hardened gear reducers still have the following problems when in use: they have high requirements for lubrication. When hardened gear reducers work under high-speed and heavy-load conditions, the pressure and relative sliding speed between the tooth surfaces are large. If the lubrication is insufficient or improper, it is easy to cause problems such as tooth surface scuffing and accelerated wear, and it will also increase the energy consumption of the power equipment matched with the gear reducer, thus affecting the performance and life of the reducer.

The bottom of the 11 is fixedly installed with a four-way connector 23. Each of the three interfaces at the top of the four-way connector 23 is fixedly connected with a connector tube 24. The three connector tubes 24 are respectively fixedly installed in the through hole 14 on their corresponding side. The whole adopts an optimized lubrication structure design. An active lubrication mechanism 2 is assembled on the reducer housing. It adopts an oil spray lubrication structure design, that is, an oil spray nozzle is set above the contact surface of the three sets of reduction gear shafts to ensure that the tooth surface is fully lubricated and cooled, avoiding problems such as tooth surface scuffing and accelerated wear, thereby reducing the energy consumption of the power equipment matched with the gear reducer, ensuring the performance and life of the reducer, and playing an energy-saving role.

[0023] The two housings 11 are arranged symmetrically and fastened with screws.

An appropriate amount of lubricating oil can be filled into the three mounting cavities 12 of its bottom housing 11. The lubricating oil can be drawn by the pump body of the pump-type sprayer 21, extracted by the lower connector pipe 24, and finally sprayed out by the upper strip nozzle 22 to achieve spraying at the contact point of the gear shaft, so as to ensure that the tooth surface is fully lubricated and cooled, avoiding problems such as tooth surface scuffing and accelerated wear, thereby reducing the energy consumption of the matching power equipment of the gear reducer, ensuring the performance and life of the reducer, and playing an energy-saving role.
