Abstract
The utility model discloses a damping limit cup of a hydraulic excavator. The damping limit cup body is a metal piece. A layer of rubber is bonded on the edge of the damping limit cup to prevent metal clashing noises during a vibration impact, and to prevent the oil water produced during the maintenance and cleaning from gathering in the damping limit cup, two groups of water (oil) drainage holes are arranged on the bottom of the damping limit cup, wherein, one group faces downwards and the other group faces downwards at an angle of 45 degrees. The hidden quality trouble due to too large vibration amplitude of an engine is solved, the clearance between a fan and a wind scooper is optimized further and the cooling effect of the radiating system is improved as well by arranging an additional limit device, a damping limit cup. Simultaneously, the assembly is simple and a better assemblability is available. The clearance between a damping limit cup and an engine support bracket is 6 millimeters, namely, the maximum vibration amplitude of the engine is no larger than 6 millimeters.
Description
Technical field
The utility model is applied to hydraulic crawler excavator engine mounting system, is the amplitude at excavator work timing system motor, the hydraulic crawler excavator vibration damping positive stop cup of the interference of protection motor and other component.
Background technology
What the hydraulic crawler excavator motor on the domestic market generally adopted at present is rubber absorbers, its mounting structure as shown in Figure 1, it is simple in structure, because excavator generally is to work on-site, complete machine is through walking on the broken terrain of being everlasting or when swing arm promotes and descend, complete machine rocks very big, thereby causes rocking of motor.Because when moment, motor rocked, damper is in compression Free Transform state, so the amplitude of vibration of motor is very big, if engine blower and wind scooper gap are too little, fan and wind scooper interference then appear, fan blade occurs when serious and fracture, cracked blade batters down quality accidents such as water tank again.Remove in addition, parts such as the air inlet system and exhaust system relevant with motor, operating mechanism, pipeline, wiring are collided with parts on every side, produce damage, and damper also damages easily.For fear of such quality accident occurring, when design, have to sacrifice cooling effect the gap between fan and the wind scooper is strengthened.
Summary of the invention
The purpose of this utility model is to provide a kind of can solve the excessive hidden danger of quality that causes of engine vibration amplitude of vibration, has proposed the spacing imagination of damping, promptly increases the damping positive stop cup.The gap digit 6mm of positive stop cup and engine support that is to say that the maximum amplitude of vibration of motor can not surpass 6mm.Produce the metal impact sound when preventing jerk, one deck rubber has bondd at the positive stop cup edge; Simultaneously, the profit that produces in order to prevent to keep in repair or clean collects in the positive stop cup, in the positive stop cup bottom design simple structure in draining (oil) hole is arranged, and is easy to manufacture, easy to install, the hydraulic crawler excavator vibration damping positive stop cup of good cooling results.
Technical solution of the present utility model is such, comprise bolt, nut, plain washer, bolt, plain washer, spring washer, engine support, big pad, shock absorber, vibration damping positive stop cup, block rubber, metalwork, hole, it is characterized in that engine support, shock absorber, excavator platform, vibration damping positive stop cup have Bolt Connection.
Vibration damping positive stop cup ring has vertical bead limit to be pasted with block rubber.
Vibration damping positive stop cup ring has upright opening, and 45 ° of holes are down arranged.
The utility model has the advantages that can solve motor rocks problem, machine run is steady, avoid the machine parts to rock collision, improve the cooling effect of cooling system, further optimized the gap of fan and wind scooper, it is simple also to have assembling, and advantage such as assembling is the desirable vibration insulating system device of hydraulic crawler excavator preferably.
Description of drawings
It is such that structure of the present utility model constitutes:
Fig. 1 is the vibration absorber cross-sectional schematic of ordinary construction.
Fig. 2 is for having adopted the utility model vibration damping cup integral installation sectional arrangement drawing.
Fig. 3 is that the utility model vibration damping positive stop cup and block rubber are installed sectional plan view.
Fig. 4 is that the utility model vibration damping positive stop cup and block rubber are installed cutaway top view.
Among Fig. 1～Fig. 4: bolt (1), nut (2), plain washer (3), bolt (4), plain washer (5), spring washer (6), engine support (7), big pad (8), shock absorber (9), vibration damping positive stop cup (10), block rubber (11), metalwork (12), upright opening (13), 45 ° of hole (14), excavator platforms (15) down.
The specific embodiment
Most preferred embodiment of the present utility model is such, with reference to Fig. 1-Fig. 4, engine support (7) is installed on the motor, and engine support (7) is connected with excavator platform (15) limit, and tightens fixing with bolt (1) by damper (9), vibration damping positive stop cup (10).After bolt (1) is tightened, damper compressive strain, engine support (7) is 6mm with the gap of vibration damping positive stop cup (10).Excavator when work, during the vibrations amplitude of vibration of motor＜6mm, the engine free vibrations; During the vibrations amplitude of vibration of motor 〉=6mm, vibration damping positive stop cup (10) intervention work, vibration damping positive stop cup (10) contacts with engine support (7), and damper (9) can not continue compressive strain.Thereby guaranteed the steady and safety of hydraulic crawler excavator, prolonged service life of a machine.Advantages such as it is simple also to have assembling, easy for operation.
Claims (3)
1, a kind of hydraulic crawler excavator vibration damping positive stop cup, comprise bolt, nut, plain washer, bolt, plain washer, spring washer, engine support, big pad, shock absorber, vibration damping positive stop cup, block rubber, metalwork, hole, it is characterized in that engine support (7), shock absorber (9), excavator platform (15), vibration damping positive stop cup (10) have bolt (1) to connect, is vibration damping positive stop cup (10) below the shock absorber (9).
2, according to the described hydraulic crawler excavator vibration damping of claim 1 positive stop cup, the main body that it is characterized in that vibration damping positive stop cup (10) is metalwork (12), and the bead limit of rim of a cup is pasted with block rubber (11).
3, according to the described hydraulic crawler excavator vibration damping of claim 1 positive stop cup, it is characterized in that vibration damping positive stop cup (10) has upright opening (13), 45 ° hole (14) are down arranged.
