Description

Technical Field

[0001] The utility model relates to the technical field of worm gear reducer processing, in particular to an oil injection device used for worm gear reducer processing. 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.

[0003] The prior art discloses an oil injection device for worm gear reducer processing with application number CN201921802103.4 and an oil injection device for worm gear reducer processing with application number CN202022841235.7. Both prior arts can achieve the purpose of oiling the reducer, but when oiling, a driving mechanism needs to be provided for the rotation of the reducer, and an oil pump mechanism is also provided to act as an oil injection power for oiling, which makes the device energy-consuming and has a high purchase cost, increasing the burden on the enterprise. Secondly, the lubricating oil in the oil storage tank of the above patents is in a relatively static state. The lubricating oil is easy to solidify at low temperatures (winter) and has poor fluidity, making it difficult to extract the lubricating oil during oil pumping, affecting the oil injection effect.

The utility model reduces the power source, reduces the cost of the device and the working energy consumption, and reduces the burden on the enterprise. In addition, the constant temperature heater can heat the lubricating oil to prevent the lubricating oil from solidifying. When the piston rod moves left and right, the gear drives the rotating shaft to rotate, and the rotating shaft can drive the stirring blade to rotate. The stirring blade can stir the lubricating oil, which increases the fluidity of the lubricating oil and ensures the normal operation of the oil filling work.

[0024] 2. The utility model is provided with a one-way screw, a threaded sleeve, a transverse slide, a longitudinal slide and a slide plate. Before work, the staff can adjust the position of the slide plate through the transverse slide and the longitudinal slide so that the oil filling head is aligned with the oil filling port of the reducer, and then rotate the one-way screw. The rotation of the one-way screw causes the threaded sleeve to move downward, thereby allowing the oil filling head to be inserted into the oil filling port. At the same time, the transverse slide will press on the reducer, thereby achieving the purpose of fixing the reducer and making the oil filling more stable. BRIEF DESCRIPTION OF THE DRAWINGS
