Torque-limited transmission worm and gear speed reducer with oil discharging and collecting device and method

Abstract

The invention discloses a torque-limited transmission worm and gear speed reducer with an oil discharge and collecting device and a method, and relates to the technical field of speed reducers. The speed reducer comprises an oil discharging and blocking assembly on a bearing frame, the oil discharging and blocking assembly comprises a linkage rod and a driving rod, a connecting sleeve ring is fixedly connected with the outer portion of one end of the linkage rod in a sleeving mode, a pulling rope is fixedly connected to the bottom end face of the connecting sleeve ring, the oil discharging andblocking assembly further comprises a sleeve fixedly connected to the other end of the linkage rod, the top end of the driving rod extends into a speed reducing mechanism and is fixedly connected with a blocking disc, the outer side of the bottom of the driving rod is movably sleeved with a limiting sleeve ring, a returning spring is fixedly connected to the outer portion of the driving rod and located between the blocking disc and the limiting sleeve ring, the oil discharging and blocking assembly is equivalent to a manual oil discharging mechanism, and when oil is discharged, lubricating grease cannot be scattered, an oil discharging port of a speed reducer is opened by utilizing the lever principle, so that the labor is saved, the structure is reasonable in and the use is convenient.

Description

technical field [0001] The invention relates to the technical field of reducers, in particular to a torque-limiting transmission worm gear reducer with an oil discharge collection device and a method thereof. Background technique [0002] The reducer is an independent component consisting of gear transmission, worm transmission, and gear-worm transmission enclosed in a rigid shell. It is often used as a reduction transmission device between the original moving part and the working machine. It plays the role of matching speed and transmitting torque between prime mover and working machine or actuator, and is widely used in modern machinery. [0003] During the early use of the reducer, since the internal worm and the reduction gear are in a running-in state, the metal impurities on the surface of the two sets of gears will fall off into the lubricating grease during the running-in process. The grease in the reducer is discharged and filtered, and the existing reducer usually...

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a torque-limiting transmission worm gear reducer with an oil discharge collection device and its method, which solves the problem that the existing reducer usually adopts two methods when draining oil. Instead of blocking, it is realized by using the control valve. Both of these two methods will cause a small amount of grease to spill out when draining oil, thus causing pollution problems.
