Description

Technical Field

[0001] The utility model relates to the technical field of mechanical equipment, in particular to a shaft-mounted helical gear hardened gear surface reducer. Background Art

[0002] The shaft-mounted helical hardened gear reducer is a commonly used transmission device, usually composed of two or more gears, whose gear axes are not parallel and the inclination angle is adjustable, which helps to reduce the interaction between gears and reduce noise and vibration. This type of reducer is usually used in industrial equipment that requires high precision and high torque transmission, such as machinery manufacturing, aerospace and automotive industries.

[0003] The Chinese patent discloses a shaft-mounted helical gear hardened surface reducer (publication number: CN212839286U), which introduces lubricating oil into the lubricating oil box through a feed pipe, and by turning the adjusting knob, the threaded rod moves up along the threaded hole, so that the rubber plug enters the lubricating oil box, and then the lubricating oil in the lubricating oil box falls on the helical gear of the helical gear transmission group, which further facilitates the lubrication of the helical gear of the helical gear transmission group. However, the device still has the following problems:

[0004] When the lubricating oil is output, the landing point of the lubricating oil is fixed at the transmission group, which is not conducive to uniform lubrication of the internal components of the transmission group. In addition, when lubricating the transmission group, the dosage of the lubricating oil is not easy to control. Excessive dosage of the lubricating oil may increase the agitation of the oil, and the lubricating oil is easy to produce foam to reduce the lubrication effect. Utility Model Content
