Description

A kind of differential mechanism rotation maintenance platform
(1) technical field
The utility model is a kind of repairing workbench, particularly relates to a kind of dedicated of the differential mechanism that services a car.
(2) background technology
Known, automobile can be turned smoothly, and we must make its driving wheel in the wheel transferring power of both sides, allow the both sides wheel with different rotating speed rotations, satisfy two sidecar wheels and do equidistantly not travel with the form of pure rolling as far as possible, reduce the friction on tire and ground.The way that addresses this problem is that drive wheel design is become two independently axles, also claims left and right half.
Open differential is made up of parts such as planetary gear, pinion frame, axle shaft gears.The power of engine enters differential mechanism through power transmission shaft, directly drives planetary wheel carrier, drives left and right two semiaxis by planetary gear again, drives left and right wheel respectively.The designing requirement of differential mechanism is satisfied: (left half axle rotating speed)+(right axle shaft rotating speed)=2 (planetary wheel carrier rotating speed).Differential mechanism be about two semiaxis, be called semiaxis in other words axletree about on the same axle center, separate separately, could form differential like this.Pinion in the housing begins to rotate when Vehicular turn.Realize that with this both sides wheel is with different rotating speed rotations.Inboard wheel changes slowly than housing.But outboard wheels will be changeed to such an extent that hurry up relatively.
Differential mechanism is the housing of a half-cone, housing has a circle flange, offer some connection apertures on the flange, parts such as distributing planetary gear, pinion frame, axle shaft gear in the open side of housing, differential mechanism needs maintenance behind the walking certain distance, need in the maintenance differential mechanism angle is held in and both be convenient to artificial place under repair operation on the workbench, wish again and can overturn in all directions, need adjust to suitable angle by repairing.
Be about seven or eight hours the maintenance time of a differential mechanism.And in the middle of the process of maintenance differential mechanism,, give and keep in repair, maintain and brought very large inconvenience, require a great deal of time and manpower because the irregular shape of differential mechanism itself, volume is big, quality is heavy.Therefore, how to improve the differential mechanism maintenance efficiency and become our current target.
Prior art is differential mechanism to be placed on the workbench keep in repair, and does not have the fixedly instrument of differential mechanism, is to need other people to assist in operation therefore, can not a people independently finish the work.And the excessive differential mechanism that makes of exerting oneself at work drops on ground, causes unnecessary accident.Pair equipment special of differential mechanism place under repair is not arranged at present as yet.
In conjunction with field investigation and consult domestic and international related data, tentatively determine the high time-consuming reason of maintenance differential mechanism: the maintenance tool that uses specialty: field operation inconvenience: two differential mechanisms are investigated repair time, found that the time of repairing all surpasses 7 hours.Because the differential mechanism quality is big, out-of-shape causes the maintenance personal to spend the plenty of time, moves the upset differential mechanism, and time and efforts consumption is too big.
(3) utility model content
The purpose of this utility model aims to provide a kind of dedicated of suitable clamping differential mechanism, and can the wish with the repairman arbitrarily overturn on workbench.
The purpose of this utility model so realizes:
A kind of differential mechanism rotation maintenance platform, it is characterized in that: a rotating frame is set on a fixed rack, and it is relative that a recess is set respectively about described framework centre, holing clip that can the shift position, a through hole is offered at the recess edge of holding frame.
Described rotating frame is by the rotary handle interlock.
At the described external bevel gear of framework center of rotation that revolves, shake bevel gear in addition with described bevel gear engagement and form bevel reduction gear set and external crank handle.
The utility model beneficial effect with advantage is: hold differential mechanism that maintenance repairs and be clamped in that a recess is set respectively about described framework centre is relative, the position of mobile holing clip, just differential mechanism is clamped in the recess of clamping, circular hole on the differential mechanism flange is relative with the through hole of clamper, link together by bolt, on the workbench of suitable height, be convenient to operated place under repair, at any time the angle that needs the conversion differential mechanism in the repairing, the manual axial handle of clamper, the handle of waving angle that perhaps shaken conversion, can make things convenient for and optionally differential mechanism be adjusted to optimum position and angle, repair so that make things convenient for subtly.The device solves of a simple structure specific purpose tool that do not have of the industry so far, improved the quality of repair work and repair in security, in case unclamp, pound down the trick and the safety of harm people.
To using and not using 12 vehicles of differential mechanism whirler to contrast, can learn clearly, shortened 3.2 hours after using this device, reached the target of having raised the efficiency before.And in maintenance process, the maintenance personal feels to use behind the machine very convenient, has also given up the potential safety hazard that exists originally.
Economic benefit measuring and calculating: to repair differential mechanism used man-hour is 10 man-hours, and be 30 yuan 1 man-hour, and be to calculate in 7 hours maintenance time, so per hour the working hour expense of Xiu Fuing: (7 ÷ 10) * 30=21 unit.Owing to used this dedicated to shorten 3 hours later on, also just equaled to have reduced 3 hours working hour expenses: 3 * 21=63 unit
Up till now for extremely, do not find to come differential mechanism is carried out high efficiency like this reparation utensil as yet according to investigations than this better sophisticated equipment.
