Abstract
The invention relates to a torsional damper of an engine. The torsional damper comprises a hub, an inertia block, a belt pulley and a rubber matrix, wherein the hub and the belt pulley are connected with each other in an integrated mode, the hub is connected with the inertia block through the rubber matrix in an interference assembling mode, the rubber matrix is arranged between the hub and the inertia block, and the rubber matrix is made of ethylene-propylene-diene monomer rubber. The inertia block and the belt pulley relatively and independently work, the inertia block is not used as a transmission part, the rubber matrix only bears dynamic load of torsion directions of the inertia block so that the requirements of the rubber matrix for fatigue endurance and service life of rubber are greatly reduced, and service life of the torsional damper is prolonged; the hub is connected with the inertia block through the rubber matrix in an interference assembling mode, the rubber matrix is arranged between the hub and the inertia block, the inertia block is not prone to drop from the outer wall of the hub even if the rubber matrix is invalid so that safe performances of the torsional damper are improved; and simultaneously, the rubber matrix is made of ethylene-propylene-diene monomer rubber, so that products can be used at the temperature of 120 DEG C for a long time and shortly or intermittently used at the temperature of 150-200 DEG C, performances of high temperature resistance and the like are improved, and market competitiveness is improved.
Description
Technical field
The present invention relates to engine art, relate in particular to a kind of engine torque vibration damper.
Background technique
Motor be a kind of can being converted into of other form another kind of can machine, normally be converted into mechanical energy to chemical energy.Motor both had been applicable to power generating apparatus, also can refer to comprise the whole machine (as: petrol engine, diesel engine, aeroengine) of power plant.Motor is born the earliest in Britain, so the concept of motor also comes from English, its literal sense refers to the sort of " producing the mechanical device of power ".
In traditional used for diesel engine torsion vibration absorber (seeing also Fig. 1), what adopt is that wheel hub 1 ', inertial mass 2 ' are directly vulcanized with colloid 4 ', owing on the inertial mass 2 ' belt pulley 3 ' is set directly, inertial mass 2 ' and belt pulley 3 ' are integrated and form, and colloid 4 ' bears the load of reversing with radial direction simultaneously;
Because the rubber vulcanization aftershrinkage makes sizing material be in all the time extended state, greatly reduce working life, and when the 4 ' inefficacy of tackiness agent colloid, inertial mass 2 ' will come off from wheel hub 1 ', in the situation of high engine speeds operation, produces fatal risk;
Colloid 4 ' is general, and what adopt is nitrile butadiene rubber, can only use below 120 ℃, and high temperature resistant, ozone, weather-proof and radiation resistance is relatively poor.
Summary of the invention
A kind of engine torque vibration damper that the object of the invention is to overcome the deficiencies in the prior art and provide.
The present invention realizes like this, a kind of engine torque vibration damper, comprise wheel hub, inertial mass, belt pulley and colloid, described wheel hub is connected with belt pulley, described wheel hub is connected with the mode of inertial mass by colloid interference assembling, colloid is located between wheel hub and the inertial mass, and the material of colloid is ethylene propylene diene rubber.
Further, described wheel hub and belt pulley are integrated and form.
Further, wheel hub, inertial mass and colloid are sulfided into one by the mode of post-cure.
Further, the material of described inertial mass and belt pulley is gray cast iron.
The advantage of engine torque vibration damper provided by the invention is: by inertial mass and belt pulley is relatively independent, independently the inertial mass of inertial mass is not as driving component, colloid only bears the dynamic load of torsional direction, make require greatly to reduce its tired durable working life to rubber, and improve working life;
Wheel hub is connected with the mode of inertial mass by the interference assembling, and colloid is located between wheel hub and the inertial mass, even colloid damage or inefficacy, inertial mass also is difficult for coming off from the wheel hub outer wall, in the situation of high engine speeds running, improves its Safety performance;
The material of colloid adopts ethylene propylene diene rubber simultaneously, so that goods can use under 120 ℃ for a long time, 200 ℃ of lower can of short duration or intermittently uses of 150-, improves the performances such as high temperature resistant, promotes the market competitiveness.
Description of drawings

Fig. 2 is the plan view of a kind of engine torque vibration damper of the present invention.
Fig. 3 is the A-A sectional view among Fig. 2.
Embodiment
In order to make purpose of the present invention, technological scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, is not intended to limit the present invention.
See also Fig. 2 and Fig. 3, wherein Fig. 2 is the plan view of a kind of engine torque vibration damper of the present invention, and Fig. 3 is the A-A sectional view among Fig. 2.
Described engine torque vibration damper comprises wheel hub 1, inertial mass 2, belt pulley 3 and colloid 4, described wheel hub 1 is connected with belt pulley 3, described wheel hub 1 is connected with the mode of inertial mass 2 by colloid 4 interference assembling, described wheel hub 1 and belt pulley 3 are integrated and form, colloid 4 is located between wheel hub 1 and the inertial mass 2, after wheel hub 1, inertial mass 2 assembles with colloid 4 again the mode by post-cure be sulfided into one.
Described inertial mass 2 is gray cast iron with the material of belt pulley 3, preferably uses HT250, and its tensile strength is large, and intensity, wear resistance, heat resistance and vibration damping are good, and castability is good.
The material of colloid 4 is ethylene propylene diene rubber, and ethylene propylene diene rubber is the terpolymer of ethene, propylene and non-conjugated diene hydrocarbon, and its topmost characteristic is exactly its superior resistance to oxidation, anti-ozone and erosion-resistant ability.Because ethylene propylene diene rubber belongs to polyolefin family, it has fabulous vulcanization characteristics.In the middle of all rubber, ethylene propylene diene rubber has minimum proportion, and it can absorb a large amount of fillers and oil and influence characteristic is little, so that the present invention can use under 120 ℃ for a long time, 200 ℃ of lower can of short duration or intermittently uses of 150-, improve the performances such as high temperature resistant, promote the market competitiveness.
By inertial mass 2 and belt pulley 3 is relatively independent, independently the inertial mass 2 of inertial mass is not as driving component, and colloid 4 only bears the dynamic load of torsional direction, makes require greatly to reduce its tired durable working life to rubber, and improves working life;
Wheel hub 1 is connected with the mode of inertial mass 2 by the interference assembling, and colloid 4 is located between wheel hub 1 and the inertial mass 2, even colloid 3 damages or inefficacy, inertial mass 2 also is difficult for coming off from wheel hub 1 outer wall, in the situation of high engine speeds running, improves its Safety performance.
The above only is preferred embodiment of the present invention, not in order to limiting the present invention, all any modifications of doing within the spirit and principles in the present invention, is equal to and replaces and improvement etc., all should be included within protection scope of the present invention.
