Abstract
The utility model relates to a special tool for wheel hub dismounting in the central transmission part of a crawler bulldozer which comprises a manually operated hydraulic station, an ultra-thin jack, a holder, twelve pull bars, four block rods, a bolt, and a gasket. The holder (7) is a recessed character type round pallet which contains 12 large holes and 4 small holes. The jack (8) is cylindrical in shape and is arranged in the holder (7); the four block rods (4) make the holder (7) and the jack (8) fixed together so as to prevent the jack from coming off when hoisting work goes on. The twelve pull bars (3) are cylindrical in shape and the middle part of each bar is provided with two milled faces. The two ends of the faces are provided with internal screw threads which are assembled together with the holder (7) through the gasket (5) and the bolt (6). The tool of the utility model is convenient and fast to operate and is also very small. The tool employs a manually operated hydraulic station in its construction, which enables it to be more conveniently carried outdoors to do repairing work. As independent components, the components of the tool can be dismounted conveniently for maintenance as well.
Description
Technical field
The utility model relates to a kind of wheel hub dismantling device, relates in particular to a kind of specific purpose tool of bull-dozer central authorities running part wheel hub dismounting.
Background technology
Pack in the bull-dozer back axle at present position of central transmission and steering cluth has been divided into three locus; The locus is very narrow and small, and the wheel hub of central running part requires and the pressure force of angular wheel shaft is 30～40 tons, in the time of any one the parts quality defects in the central transmission; All require to pull down wheel hub; In order to reduce workload, do not pull down under the situation of driving-disc on the final deceleration assembly, in limited space the intact difficulty of pulling down very of wheel hub.
The utility model content
The utility model is to overcome above-mentioned deficiency, to the actual conditions of crawler dozer, in conjunction with drawing requirement studied a kind of special use and drawn tool, it can be in limited space be pulled down wheel hub is intact.
The utility model is for realizing above-mentioned purpose, and adopt following technical scheme: adopt a ultrathin hydraulic jack, pressure reaches 100 tons (60Mpa); Stroke 57mm (, consider deflection, therefore select for use stroke bigger) though be that wheel hub and angular wheel shaft are the awl splined; Designed the instrument that a cover cooperates jack to use according to drawing, it is by hand-hydraulic station, base; Pull bar, lever, bolt and packing ring are formed; It is characterized in that: base 7 is round trays of a concave character type, and 12 macropores and 4 apertures are arranged above.Jack 8 be one cylindrical, 8 on jack has been fixed on base 7 and jack 8 together through 4 levers 4 in base 7, avoids jack 8 landings when lifting.12 pull bars 3 are cylindrical, and there are two planes of milling the middle part, and there is internal thread at two ends, with plain washer 5 and bolt 6 itself and base 7 are fitted together.Through 24 bolts; 12 pull bars and 4 levers link three parts of the wheel hub in jack and base and the central transmission firmly, handle the hand-hydraulic station, and Hydraulic Station is to the jack fuel feeding; In limited space, the principle of utilizing active force and reaction force is with the intact dismounting of wheel hub.
The beneficial effect of the utility model: this is convenient to operation, and is simple to operate, safe and reliable, and what adopt simultaneously all is individual components, and easy accessibility is convenient to maintenance and maintenance.And this instrument is very small and exquisite, adopts the hand-hydraulic station, and is easy to carry, is applicable to that more maintenance is used outside.

As shown in the figure: the assembly figure of a kind of specific purpose tool of bull-dozer central authorities running part wheel hub dismounting
1. hand-hydraulic station 2. Pressure gauges 3. pull bars 4. levers 5. plain washers 6. bolts 7. bases 8. jack 9. wheel hubs 10. angular wheel shafts
The specific embodiment
Be described in detail in conjunction with the enforcement of accompanying drawing the present technique scheme.
It is by the hand-hydraulic station, base, and pull bar, lever, bolt and packing ring are formed, and it is characterized in that: base 7 is round trays of a concave character type, and 12 macropores and 4 apertures are arranged above.Jack 8 be one cylindrical, 8 on jack has been fixed on base 7 and jack 8 together through 4 levers 4 in base 7, avoids jack 8 landings when lifting.12 pull bars 3 are cylindrical, the middle part have two mill the plane, purpose is to use spanner in order to install, and avoids skidding; There is internal thread at two ends, with plain washer 5 and bolt 6 itself and base 7 are fitted together, and at this moment base 7; Jack 8, lever 4, pull bar 3 have just constituted an integral body.
Assembling sequence: base 7 is placed on the smooth ground, and jack 8 is placed on the relevant position of base 7, assembles 4,12 pull bars of 4 levers, 3 usefulness plain washers 5 then and with bolt 6 itself and base is fixed.Sling the handle position of jack with this instrument back axle of putting into support assembly slowly with suspender then, with 12 bolts 6 and plain washer 5 this specific purpose tool is connected with wheel hub 9 again, require 24 bolts must be tightened to the position.
Operation principle: sling the handle position of jack with this instrument back axle of putting into support assembly slowly with suspender, with 12 bolts 6 and plain washer 5 this specific purpose tool is connected with wheel hub 9, at this moment this specific purpose tool has been fixed on wheel hub 9 firmly; Open hand-hydraulic station 1, suppress for jack 8, the piston portion of jack 8 is just started working; Stretching out slowly after the spindle nose with angular wheel shaft 10 contacts, continues to give jack 8 to suppress; Utilize the principle of active force and reaction force; Just can wheel hub be dismantled, through observing manometric numerical value, know and adopted great power that it is dismantled simultaneously.
The above is exactly the preferred embodiment of the utility model, and every technical spirit according to the utility model is to any simple modification, equivalent variations and modification that above embodiment did, all still belongs in the scope of technical scheme of the utility model.
