Description
Technical field
The utility model relates to diesel engine, relates in particular to a kind of flywheel press mounting device for diesel.
Background technology
It is a kind of common fit system in the plant equipment that axis hole cooperates, the rotating manner that shaft hole mode cooperates other rotating manner cooperation relatively can be born bigger load, and the precision of transmission is also than higher, therefore in plant equipment, especially in some multi-cylinder engines, use very many, picture diesel engine flywheel crankshaft revolute pair is exactly that a common axis hole formula rotates.But, when the bent axle taper hole as diesel engine flywheel crankshaft revolute pair being carried out the axis hole installation but is a problem that is not easy to solve: because when interference fit is carried out in such crankshaft-flywheel hole, need to adopt the special process equipment, simultaneously, owing to be subjected to the locus restriction, therefore, inconvenient operation, flywheel be pressed into neither be very all even ideal.
The utility model content
The technical problems to be solved in the utility model is: provide a kind of flywheel evenly is pressed into flywheel press mounting device for diesel on the bent axle.
In order to overcome the defective that exists in the background technology, the technical scheme that its technical problem that solves the utility model adopts is: a kind of flywheel press mounting device for diesel, comprise hydraulic means, flywheel, bent axle, hydraulic means is included under the effect of hydraulic means flywheel is press-fited the push pedal of work and the oil cylinder of being made up of piston and cylinder body, push pedal is between cylinder body and flywheel, be provided with pull bar in the piston, and pull bar passes piston, push pedal, pull bar one end and bent axle flexibly connect, and the pull bar other end and piston flexibly connect.
According to another embodiment of the present utility model, flywheel press mounting device for diesel comprises that further described pull bar and bent axle are by being threaded.
According to another embodiment of the present utility model, flywheel press mounting device for diesel comprises that further described pull bar cooperates with push pedal, piston clearance.
According to another embodiment of the present utility model, flywheel press mounting device for diesel comprises further that described pull bar and piston link also are provided with and leans against nut, pull bar with lean against nut inner thread and be connected, lean against nut end face and piston end surface offsets.
According to another embodiment of the present utility model, flywheel press mounting device for diesel further comprises and also comprises locking nut, described locking nut with lean against the nut external screw thread and be connected, locking nut end face and cylinder body end face offset.
According to another embodiment of the present utility model, flywheel press mounting device for diesel comprises that further the described nut that leans against circumferentially is provided with screw, screw with lean against nut thread and be connected.
According to another embodiment of the present utility model, flywheel press mounting device for diesel comprises that further described cylinder body and piston adopt the seal sealing.
The utility model advantage is as follows: adopt said structure, because pull bar one end is threaded with bent axle, the pull bar other end with lean against thread, internal thread and be connected, and piston and lean against screw thread and offset, be that the relative bent axle of piston is motionless, and when charging into hydraulic oil in the oil cylinder, hydraulic-driven power drives cylinder body and axially drives push pedal, push pedal axially drives flywheel, has guaranteed the rigidity of push pedal, also unusual all even ideal just when flywheel is pressed into the bent axle cone, and the utility model volume is little, be not subjected to spatial constraints, easy to operate, safe and reliable.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the structural representation of preferred embodiment of the present utility model;
Wherein: 1, flywheel, 3, bent axle, 5, push pedal, 7, piston, 9, cylinder body, 11, oil cylinder, 13, pull bar, 15, lean against nut, 17, locking nut, 19, screw.
The specific embodiment
With preferred embodiment the utility model is described in further detail in conjunction with the accompanying drawings now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
Flywheel press mounting device for diesel as shown in Figure 1, comprise a kind of flywheel press mounting device for diesel, comprise hydraulic means, flywheel 1, bent axle 3, hydraulic means is included under the effect of hydraulic means flywheel 1 is press-fited the push pedal 5 of work and the oil cylinder of being made up of piston 7 and cylinder body 9 11, push pedal 5 is provided with pull bar 13 in the piston 7 between cylinder body 9 and flywheel 1, and pull bar 13 passes piston 7, push pedal 5, pull bar 13 1 ends and bent axle 3 flexibly connect, and pull bar 13 other ends and piston 7 flexibly connect.Wherein said pull bar 13 and bent axle 3 are preferably by being threaded.And pull bar 13 and push pedal 5, piston 7 matched in clearance can guarantee that like this push pedal 5 axially press-fits flywheel 1.
In addition, pull bar 13 also is provided with piston 7 links and leans against nut 15, pull bar 13 with lean against nut 15 internal threads and be connected, lean against nut 15 end faces and piston 7 end faces offset, can install convenient disassembly afterwards at flywheel 1 and bent axle 3 like this.Lean against nut 15 external screw threads and be connected with locking nut 17, locking nut 17 end faces and cylinder body 9 end faces offset, and play position-limiting action to leaning against nut 15.And, leaning against nut 15 and circumferentially be provided with screw 19, screw 19 is threaded with leaning against nut 15, adopts aforesaid way easily pull bar 13 to be back-outed from bent axle 3 screwed holes.
In order to guarantee that piston 7 and cylinder body 9 are tightly connected, the utility model adopts cylinder body 9 and piston 7 to adopt the seal sealing.
