Abstract
The invention discloses an oil pump gear dismounting device of a diesel engine, relates to a dismounting device of a bearing and a gear shaft of an oil pump transmission gear of the diesel engine. The oil pump gear dismounting device is mainly used for solving the problems of damage of a bearing, a spline shaft and a bearing installing hole at different degrees, low efficiency, big labor intensity, and delay of working schedule caused by using a hand hammer and a copper bar in the course of dismounting and mounting an oil pump idle wheel, an active gear shaft and a bearing of a locomotive diesel engine. A supporting plate is fixed on a leading screw through a screw nut; three adjustable supporting bolts are evenly arranged on the same one circumference along the axial direction of the supporting plate, and fixed on the supporting plate through a locking nut. By means of the spiral transmission principle, the working point is converted from the point contact before to the face contact, the acting area is enlarged, the work is stable, and the dismounting force is big; thus the oil pump gear dismounting device well solves the conditions of uneven acting point, big impact and incapability of using moment; besides, the oil pump gear dismounting device is compact in structure, convenient to dismount and mount, and able to largely improve the production efficiency and lighten the labor intensity.
Description
Technical field
The present invention relates to diesel engine oil pump gear disassembling device, relate to the bearing of diesel engine of locomotive transmission gear of engine oil pump and the provision for disengagement of gear shaft specifically.
Background technology
Instrument for DF8B type and DF11 type locomotive diesel engine oil pump idle pulley and driving gear shaft and bearing removal has pin removal, but the axle can only dismantled under normal circumstances and bearing, take-down time is long, in order to save time, all that the method adopting copper rod or hand hammer to knock destructive dismounting is carried out at present, the dismounting of this method, larger to the impact of bearing and splined shaft, because active force is unbalanced, the inaccuracy of beating point, damage in various degree is all caused to bearing and splined shaft and bearing mounting hole, because working space is little when particularly carrying out dismounting onboard, hand hammer and copper rod do not have usage space, easier inevitable infringement is caused to workpiece, thus cause work step loaded down with trivial details, cost is high, efficiency is low, labour intensity is large, the investigation failure cause time is long, delay job schedule.
Summary of the invention
The object of the invention is for above-mentioned deficiency, and a kind of operating efficiency proposed is high, diesel engine of locomotive lubricating oil pump idle pulley and driving gear shaft and bearing can not be made to cause gear when dismantling and assemble, splined shaft, cause damage with body installing hole, bearing and the gear disassembling device of labour intensity can be reduced.
Technical solution of the present invention is: diesel engine oil pump gear disassembling device is: gripper shoe is fixed on leading screw by feed screw nut, along gripper shoe axial, be circumferentially evenly provided with three adjustable supports bolts same, adjustable supports bolt is fixing on the supporting plate by locking nut.
Technical solution of the present invention wants three described carrying bolts and feed screw nut to be located at respectively on the two sides of gripper shoe.
This practical employing lead screw transmission and hydraulic transmission principle, reach operation controllability, the moment acted on axle and bearing is evenly adjustable, effectively can avoid damaging in operating process axle and bearing and axle bearing mount portion position; The present invention utilizes worm drive principle, and work is puted forth effort
pointfor from before point cantact be converted to
facecontact, puts forth effort area and strengthens, therefore functioning equalization, dismounting strength is large, solves impetus well uneven, the problem that impulsive force is large; The present invention is not only easy to operate, laborsaving, as long as and once dismounting task can be completed by two hours, substantially increase production efficiency; Structure of the present invention is simple, and cost is low, compact conformation, easy accessibility.

Fig. 3 is that the present invention dismantles pump with schematic diagram during wheel.
Detailed description of the invention
As shown in Figure 1, a leading screw 1 is fixed with gripper shoe 5 by feed screw nut 6, gripper shoe 5 matched in clearance is sleeved on leading screw 1, gripper shoe 5 is connected with three adjustable supports bolts 3 vertically, it is circumferentially same that three adjustable supports bolts 3 are evenly distributed on gripper shoe 5, and normal thread is connected in gripper shoe 5, adjustable supports bolt 3 is provided with locking nut 4, three adjustable supports bolts 3 and feed screw nut 6 points are located on the two sides of gripper shoe 5, can adjust the position of gripper shoe 5 on leading screw 1 by feed screw nut 6.
As shown in Figure 2, first pull down the oily earth's crust free end screen pack during dismounting pump driving gear 10, leading screw 1 is penetrated from splined shaft, and leading screw 1 rearward end and splined shaft end face are fitted tightly; Then adjusting three adjustable supports screws 3 in gripper shoe 5 makes gripper shoe 5 end face parallel with oil sump end face, tighten locking nut 4, tighten feed screw nut 6 by adjusting screw 1 in gear shaft center, turn feed screw nut 6 clockwise and just gear 10 can be pulled down smoothly.If need dismounting pump main drive gear bearing 9, can in the step of above-mentioned dismounting pump driving gear 10 (carrying out when must first pump gear be disassembled), pad 2 is inserted in leading screw 1 penetrate again in splined shaft, now adjusts pad 2 placed in the middle, bearing 9 can be pulled down by above-mentioned steps.
As shown in Figure 3, dismounting pump idle pulley 7, leading screw 1 is screwed in pump idler shaft 12 screw, screw thread is all screwed into, gripper shoe 5 is inserted in leading screw 1, wherein gripper shoe 5 supporting screws 3 contact with oil sump, and two other supporting screw 3 contacts with pump idle pulley 7, now must adjust gripper shoe 5 parallel with oil sump end face; Adjustment adjustable supports bolt 3 makes leading screw 1 vertical with gear face and tightens feed screw nut 6; Turn nut 6 clockwise, now just pump idle pulley 7 can be disassembled; If run into gear shaft or bearing because other reasons to have damaged distortion serious, can add hydraulic means between gripper shoe 5 and feed screw nut 6, such as B rifle is dismantled.
