Abstract
The utility model relates to an elastic coupling pin detaching device belonging to elastic coupling pin detaching tool technical field. The utility model is mainly to solve the problem that because the elastic coupling pin between the flange of the front gear box and the motor flange of the gas engine is detached by the hammering of a hammer in prior art, the screwed cap of the pin head can be broken and the pin lever screwed buckle can be hammered to be broken, the axial change of the motor shaft is increased and the work efficiency is low. The utility model is characterized in that a L-shaped main cylinder is provided; a handle which is also can be used as a sealing cover is arranged at the top end of the long cylinder of the main cylinder; a piston II is arranged at the side of the short cylinder; a lead screw is arranged on the handle, a piston I is arranged at the inner end of the lead screw. The utility model is characterized in even force, no damage to pin lever screwed buckle, flange and motor shaft, reusable pin, so the work efficiency is greatly enhanced, the labour strength of operation personal is reduced, the operation is convenient and easy; the utility model is mainly used for detaching the excitation motor flange and starting the coupling pin between the motor flange and the gear box flange.
Description
Technical field
The utility model belongs to elastic coupling pin extracting tool technical field, is specifically related to a kind of stripping attachment that excitation electromotor, starter-generator elastic coupling pin are dismantled in the rail locomotive overhaul that is used for.
Background technology
At present, all adopt the elastic coupling pin between diesel locomotive front gear box flange and the motor flange, anti-vibration performance is not only arranged, and warp-wise between small electromotor and the gearbox, the axial offset deviation of aspect effectively, position accuracy demand when having reduced plant equipment and installing.Owing to be resilient connection, thereby play the rigidity that relaxes between gearbox and the motor and impact that the absorbing high-frequency vibration reduces the effect of noise.But in real work, because the situation of starter-generator and excitation electromotor often appears changing in a variety of causes, before changeing motor, at first to pull down the shaft coupling pin, in the real work now, be to withdraw from Hammer the first pin of hammering elasticity coupled axle-pin, because distance is near between pin end screw rod and the motor, as the excitation electromotor side end face from 85 millimeters of pin end screw rods, starter-generator is from 125 millimeters of pin end screw rods, the direction that the direction of dynamics and elastic coupling pin withdraw from during hammering is inconsistent, bad exerting all one's effort, and shaft coupling pin forward part is taper, firm back forms interference with the special-purpose iron pad of O type and is connected, and string has O type rubber ring on the shaft coupling pin, has a rebound during hammering, and frequent appearance will be sold a nut and be smashed, pin rod screw thread hammer is bad, pound pin and but pound the situation of motor flange.In addition, because motor flange is that interference is connected with motor shaft, hammering can produce certain influence to motor shaft on motor flange the time, the situation that the motor flange slight deformation occurs and the motor shaft axial movement value is increased, because operation is bad, the shaft coupling pin that occurs a motor of dismounting sometimes is also longer than the time of adjusting a motor cost.
Summary of the invention
The purpose of this utility model is exactly that a kind of elastic coupling pin stripping attachment that is used to dismantle elastic coupling pin between diesel locomotive front gear box flange and excitation electromotor flange, the starter-generator flange is provided at above-mentioned weak point.
Technical solution of the present utility model is: a kind of elastic coupling pin stripping attachment is characterized in that comprising " L " type Master cylinder body; The upper end of the long cylinder part of this Master cylinder body is provided with the double handle of doing capping, and the sidepiece of short cylinder part is provided with piston I I; Leading screw is housed on the handle, and the leading screw inner end is provided with piston I.
Handle outer surface described in the technical solutions of the utility model is provided with annular knurl.
Leading screw described in the technical solutions of the utility model is the leading screw of M20, and the upper end is the nut of M24.
The utility model is owing to adopt by " L " type Master cylinder body, handle, leading screw, the elastic coupling pin stripping attachment that piston I and piston I I constitute, and " L " type Master cylinder body can be changed force direction 90 ° of angles, the short cylinder part of Master cylinder body is narrower, can put between motor side and the pin end face screw rod, like this, with the nut of wrench rotating threaded shaft upper end, leading screw rotates, and it is descending to promote piston I, promoting piston I I by grease moves to pin head direction, the elastic coupling pin is loosening, since stressed even, to the screw thread of pin, flange, motor shaft is not damaged all, pin can be used again, operating efficiency is improved greatly, alleviate labor intensity of operating personnel, and easy to operation.The utility model is because at handle outer surface annular knurl, thereby can increase the frictional force of hand-held handle, makes more convenient operation, stable.The utility model is owing to adopt the leading screw of M20, and the upper end is the nut of M24, and the nut of existing shaft coupling pin is M24, thereby matching board hand in addition, uses existing M24 wrench to get final product rotational lead screw, and is very convenient.The utility model is mainly used in the shaft coupling pin between dismounting excitation electromotor flange, starter-generator flange and the gearbox flange in the rail locomotive overhaul.
Description of drawings
Fig. 1 is the structural representation of position between rail locomotive front gear box and excitation electromotor, the starter-generator;
Fig. 2 is a structural representation of the present utility model.
The specific embodiment
As shown in Figure 1.Starting gearbox 2 is the rail locomotive front gear box.The flange of excitation electromotor 1 is connected by the elastic coupling pin with the flange that starts gearbox 2, and excitation electromotor 1 side and pin end screw rod distance L are 85 millimeters.The flange of starter-generator 4 is connected by elastic coupling pin 3 with the flange that starts gearbox 2, and starter-generator 4 sides and pin end screw rod distance L are 125 millimeters.
As shown in Figure 2.Master cylinder body 10 is " L " type, in butter 8 is housed.Handle 6 spinnings are in the upper end of the long cylinder part of Master cylinder body 10, and the outer surface annular knurl has sealing role.Screw mandrel 5 is the leading screw of M20, and the upper end nut is M24, is contained on the handle 6.Leading screw 5 inner ends are provided with piston I 9.Piston I I7 is located at the sidepiece of the short cylinder part of Master cylinder body 10, is used for the top and hits the pin head, has promptly changed 90 ° of angles.The width of the short cylinder part of Master cylinder body 10 can be 80 millimeters or 120 mm wides, thereby can snap between excitation electromotor 1, starter-generator 4 sides and the flange.
