Abstract
The utility model discloses a special tool for detaching a housing of a wheel reduction gear of a freight vehicle, wherein a screw hole is formed at the center of a circular pressure disc, a plurality of through holes are formed on the surface of the circular disc at equal intervals along the circumferential direction, external threads are formed at the bottom end of a sliding weight rod, a circular flange is arranged at the top end of the sliding weight rod, a sliding weight is sheathed into the sliding weight rod, a locking nut is screwed at the external threads at the bottom end of the sliding weight rod and the bottom end of the sliding weight rod is screwed in the screw hole at the center of the circular pressure disc. By utilizing the tool, the housing of the wheel reduction gear with a damaged thread hole can be conveniently detached, so that a half axle of the vehicle is prevented from shedding, the vehicle overhaul efficiency is improved, and the normal running of the vehicle is ensured.
Description
Technical field
The utility model relates to a kind of goods stock hub reduction gear shell dismounting specific purpose tool.
Background technology
Usually load-carrying truck wheel limit is provided with decelerator, as ACTROS4141 type vehicle etc., road conditions are different because goods stock travels, often need through road surfaces such as all kinds of hollows pools, cause vehicle chassis corroded by the water logging bubble, hub reduction gear parts and brake corrosion degree are serious, have aggravated the wearing and tearing of vehicle part, have shortened the vehicle maintenance cycle greatly.In the car inspection and repair process, when dismounting hub reduction gear shell because original three dismounting screwed holes rust that become 120 degree angles are mashed, downright bad and can't recover screw thread pair, the hub reduction gear shell is installed the faying face corrosion and is bonded together, and causes hub reduction gear shell dismounting difficulty.Adopt conventional method for dismounting just to lack operability for the dismounting of the hub reduction gear shell of thread failure, operating efficiency is low, the improper meeting of method for dismounting causes parts damages, particularly the semiaxis of vehicle takes off in differential pinion gear, cause pinion frame to come off, it is in place that semiaxis can't be filled in, and will dismantle differential mechanism like this, causes workload to increase.For avoiding semiaxis to come off, in the unloading process, need people's field-strip, another human hand push is lived semiaxis, prevents that semiaxis is along with planetary gear is followed out together.Above-mentioned upkeep operation is wasted time and energy, and efficient is low, has had a strong impact on the normal operation of vehicle.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of goods stock hub reduction gear shell dismounting specific purpose tool, this instrument of utilization can be for convenience detach the hub reduction gear shell that damages of screwed hole, avoided coming off of vehicle semiaxis, improve the efficient of car inspection and repair, guaranteed the normal operation of vehicle.
For solving the problems of the technologies described above, the utility model goods stock hub reduction gear shell dismounting specific purpose tool comprises circular platen, sliding hammer stem, sliding hammer and locking nut, described circular platen center has screw and disc face and along the circumferential direction is arranged with at interval etc. some through holes, described sliding hammer stem bottom is provided with external screw thread and the top is provided with round flange, described sliding hammer is inserted in described sliding hammer stem, described locking nut is twisted in described sliding hammer stem bottom external screw thread, and twist in described circular platen center screw described sliding hammer stem bottom.
Further, the disc face of above-mentioned circular platen along the circumferential direction waits at interval and is arranged with ten through holes.
For ease of holding sliding hammer sliding hammer is moved along sliding hammer stem, above-mentioned sliding hammer side face middle part is provided with interior concaved circular cambered surface.
Be the convenient portable and sliding hammer stem of rotation, this instrument also comprises handle, and described handle is located at described sliding hammer stem top.
Because the utility model goods stock hub reduction gear shell dismounting specific purpose tool has adopted technique scheme, be that circular platen center has screw and disc face is arranged with some through holes along circle spacing etc., sliding hammer stem bottom is provided with external screw thread and the top is provided with round flange, sliding hammer is inserted in sliding hammer stem, locking nut is twisted in sliding hammer stem bottom external screw thread, and twist in described circular platen center screw sliding hammer stem bottom.This instrument of utilization can be for convenience detach the hub reduction gear shell that damages of screwed hole, avoided coming off of vehicle semiaxis, improved the efficient of car inspection and repair, guaranteed the normal operation of vehicle.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and embodiments:
Fig. 1 is the structural representation of the utility model goods stock hub reduction gear shell dismounting specific purpose tool.
The specific embodiment
As shown in Figure 1, the utility model goods stock hub reduction gear shell dismounting specific purpose tool comprises circular platen 1, sliding hammer stem 2, sliding hammer 3 and locking nut 4, described circular platen 1 center has screw 12 and disc face along the circumferential direction is arranged with some through holes 11 in interval etc., described sliding hammer stem 2 bottoms are provided with external screw thread 22 and the top is provided with round flange 21, described sliding hammer 3 is inserted in described sliding hammer stem 2, described locking nut 4 is twisted in described sliding hammer stem 2 bottom external screw threads 22, and twist in described circular platen 1 center screw described sliding hammer stem 2 bottoms.
Further, the disc face of above-mentioned circular platen 1 along the circumferential direction waits at interval and is arranged with ten through holes 11.
For ease of holding sliding hammer sliding hammer is moved along sliding hammer stem, concaved circular cambered surface 31 in above-mentioned sliding hammer 3 side faces middle part is provided with.
Be the convenient portable and sliding hammer stem of rotation, this instrument also comprises handle 5, and described handle 5 is located at described sliding hammer stem 2 tops.
During the dismounting of hub reduction gear shell, circular platen is passed through bolt, some through holes of disc face and hub reduction gear end cap screw are fixed in hub reduction gear outer face and fastening, sliding hammer stem, sliding hammer, to slide hammer stem after the locking nut assembling twists in circular platen center screw, by screwing the top that screw thread makes sliding hammer stem bottom withstand semiaxis, prevent that semiaxis from outwards moving, hold the round flange of sliding hammer along the sliding hammer stem of sliding hammer stem repeated stock top, the impulsive force of sliding hammer passes to disk by sliding hammer stem and makes it to be pulled outwardly to the hub reduction gear shell again, and the hub reduction gear shell is split out.Also can adopt hammer to knock circular platen Wai Yuan end in the unloading process to increase impulsive force, if the hub reduction gear shell has loosening sign in unloading process, to slide hammer stem again screws in the direction of the clock, make sliding hammer stem bottom continue to withstand till the semiaxis, in case semiaxis is deviate from, whole unloading process does not touch the hub reduction gear shell, avoids the damage of unloading process miscellaneous part.Whole unloading process only needs people's operation, and is time saving and energy saving, effectively improved overhaul efficiency, guaranteed the normal operation of vehicle.
