Description
Technical field
The utility model belongs to dynamic power machine technical field, has related to a kind of engine blower damper components, has related in particular to a kind of loose-prevention type engine blower vibration damper.
Background technique
At present, in all kinds of engine blower damper components operation process, the rubber ring between fan shock absorber component two flanges very easily damages and lost efficacy in fan runs up process; And when motor is worked under bad working environments, because the vibration of motor causes fan collision wind shelling cover, making rubber ring bear shearing force strengthens, the comprehensive function of each side makes fan shock absorber component two flanges easily get loose at rubber ring place, cause fan to fly out, damage water tank and other frontal attachments, not only make motor run well, and maintenance cost is high.In order to prevent that fan from flying out, some anticreep damper components on market, are released, if Chinese Patent Application No. is 201120465290.9 to disclose a kind of engine cooling system fan vibration absorption coupling assembly, it comprises fan vibration absorption coupling and joining shaft flange, anti-decylization is placed in fan vibration absorption coupling die cavity, is spill also and the cooperation of joining shaft flange, gapped between anti-decylization and fan vibration absorption coupling die cavity inwall, when fan running, between anti-decylization and coupling, can not produce interference; Anti-decylization is provided with flanging outward at the die cavity of fan vibration absorption coupling; If losing efficacy, fan vibration absorption coupling departed from motor output terminal, and anti-decylization is still by bolton and motor joining shaft, because anticreep endless belt has flanging, fan coupling can not be deviate from, the fan abnormal sound causing that now lost efficacy can remind driver to change in time accessory, avoid breaking the generation of the more holocaust accidents such as water tank, played safety protection function.Although this technological scheme has played good protective action, its effectiveness in vibration suppression but decreases.Therefore, on market, still need the more rational damper components of a kind of project organization.
Summary of the invention
The purpose of this utility model is to provide a kind of loose-prevention type engine blower vibration damper and assembly method thereof of simple in structure, easy accessibility.Fan shock absorber component of the present utility model can not only play good effectiveness in vibration suppression, more can effectively prevent from damaging when flange from getting loose fan, batter down the frontal attachments such as water tank, has improved the reliability of fan shock absorber component, effectively reduces maintenance cost.
To achieve these goals, the utility model has adopted following technological scheme:
A kind of loose-prevention type engine blower vibration damper, comprise flange I, flange II, anticreep packing ring and be arranged on flange I and flange II between damped rubber ring; The attachment face of described flange I is provided with boss; The internal diameter of described flange II is provided with anticreep projection; In the time that fan shock absorber component is installed, anticreep packing ring is fixed on the boss of flange I by bolt assembly, under boss, anticreep projection and anticreep packing ring triple interaction coordinate, when damped rubber ring was lost efficacy, anticreep packing ring stops the anticreep projection of flange II inner radius, prevents that flange II from deviating from.
In the utility model, the flange I attachment face of fan shock absorber component has the internal diameter of anticreep installation base, flange II to have anticreep projection, in operation process, use the barrier functionality of anticreep packing ring, flange II can axially not be moved along flange I, thereby stop the aging rear flange II of the rubber ring flange I that flies out, damage fan, batter down the frontal attachments such as water tank.
Further illustrate as of the present utility model, both are axially arranged with gap the anticreep projection of the boss of the attachment face of described flange I and flange II inner radius, and both are directly contact not; Effectively avoid after fan shock absorber component assembling anticreep packing ring, because the too small formation in gap is axially without the situation of vibration damping, effectively reducing engine snubber rate of fault, ensure that fan shock absorber component is respectively to effectiveness in vibration suppression simultaneously.
A method of assembling above-mentioned loose-prevention type engine blower vibration damper, comprises the following steps:
First, use press mode that damped rubber ring is pressed between flange I and flange II, this process is used reliable frock to ensure the relative position between two flanges;
Then, use anticreep packing ring and bolt assembly that fan shock absorber component is fixed on to relevant position on motor, will on bolt assembly, arrive form-fit torque.
The advantage that the utility model possesses:
1. there is good effectiveness in vibration suppression;
2. effectively prevent that flange from deviating from;
3. reduce fan, water tank and frontal attachments rate of fault;
4. reduce after-sales service cost;
5. simple in structure, easy disassembly;
6. extend fan, water tank and frontal attachments working life.

Embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated, but do not limit protection domain of the present utility model.
Embodiment 1:
As Figure 1-5, a kind of loose-prevention type engine blower vibration damper, comprise flange I 1, flange II 3, anticreep packing ring 5 and be arranged on flange I 1 and flange II 3 between damped rubber ring 2; The attachment face of described flange I 1 is provided with boss 11; The internal diameter of described flange II 3 is provided with anticreep projection 31; In the time that fan shock absorber component is installed, anticreep packing ring 5 is fixed on the boss 11 of flange I 1 by bolt assembly 4, under boss 11, anticreep projection 31 and anticreep packing ring 5 triple interactions coordinate, when damped rubber ring 2 was lost efficacy, anticreep packing ring 5 stops the anticreep projection 31 of flange II 3 inner radius, prevents that flange II 3 from deviating from.Both are axially arranged with gap the anticreep projection 31 of the boss 11 of the attachment face of described flange I 1 and flange II 3 inner radius, and both are directly contact not.
