Speed differential mechanism of winching grinder

Abstract

The invention relates to a differential mechanism of entwisting milling device that includes a camshaft, a pair of left string quantity gear and right string quantity gear, an output shaft that one end has shaft disc connecting to left and right string quantity gear, a gear ring that keeps eccentricity with left and right string quantity gear and keeps concentricity with shaft disc, a pair of left and right end cover. The feature is that the gear wrist connects to a bearing disc after passing through left and right string quantity gear, and the right bearing disc locates on camshaft. The advantages of the invention are that it has entirely frame structure and gear wrist would not have distortion and broken, which is benefit for ensuring safety.

Description

technical field [0001] The invention relates to a differential mechanism of a winch mill, which is used for traction, line tightening, vertical rods, vertical towers, power equipment such as transformers and power distribution cabinets during construction and maintenance of power transmission and transformation lines, etc. It plays the role of changing the speed ratio on the winch mill of the special facility, and belongs to the technical field of electric power construction equipment. Background technique [0002] Before the differential mechanism of the winch involved in the Chinese patent CN2848809Y was released, because the gearbox of the winch commonly contained a differential and a speed change mechanism, that is, the differential mechanism and the speed change mechanism were jointly arranged in the gearbox , so there are four disadvantages. First, in order to configure the aforementioned two mechanisms in the gearbox, the volume of the gearbox must be appropriately in...

Problems solved by technology

It can be seen from this that one group of gear pin shafts 211 is in a cantilever state, that is to say that the tops (right end in the figure) of one group of gear pin shafts 211 do not have any parts to give coupling tubes, and are very prone to deformation during use, and even due to Fracture caused by fatigue leading to major accidents

Moreover, the applicant has carried out actual test observation and analysis on a group of gear pin shafts 211 of the above-mentioned structure, and the result is that a group of gear pin shafts 211 cannot well reflect the joint action, that is, they cannot bear forces at the same time, and often appear as one group of gear pin shafts 211. Every two cams are under force when they are perpendicular to the left and right cams 11 and 12, and the rest are in a negative state, which also increases the probability of deformation and fracture

In theory, it seems that the above situation will not occur, but due to the objective constraints of machining accuracy and assembly technology, the above phenomenon is inevitable.
