In order to extend the life-span of silicon oil damper in present common technology, pay much attention to the monitoring of the maximum temperature of silicon oil damper, when general silicon oil damper is more than 120 DEG C, the easy aged deterioration of silicone oil, but few temperature controlling silicone oil under low-temperature condition.At present, the design proposal of silicone oil operating temperature under low-temperature condition is not also ensured.
Model utility content
Technical problem to be solved in the utility model is: provide a kind of engine shaft system vibration damping equipment, the temperature of silicone oil can be raised fast, strengthen frequency modulation, the amplitude modulation ability of silicon oil damper, be conducive to the torsional oscillation situation improving axle system, be conducive to the life-span extending silicon oil damper simultaneously.
For solving the problems of the technologies described above, the technical solution of the utility model is: engine shaft system vibration damping equipment, comprise bent axle, engine front end shield is stretched out in the front end of described bent axle, the front end of described bent axle is provided with silicon oil damper and crank pulley, described silicon oil damper is arranged near described engine front end shield, thermal shield is provided with between described silicon oil damper and crank pulley, the neutral position of described thermal shield is provided with through hole, the outward edge of described thermal shield arranges towards described engine front end shield and is fixedly installed in described motor head and covers, the inner side of described thermal shield is installed with the heating equipment for heating silicone oil.
Improve as one, described motor head covers and is provided with boss, and the outward edge of described thermal shield is fixedly installed on described boss by fastening piece.
As further improvement, the outward edge of described thermal shield is distributed with some radiation holes.
Improve as one, described heating equipment is electromagnetic induction heater.
After have employed technique scheme, the beneficial effects of the utility model are: owing to being provided with thermal shield between the silicon oil damper of engine shaft system vibration damping equipment and crank pulley, the inner side of described thermal shield is installed with the heating equipment for heating silicone oil, described thermal shield is fixedly installed in described motor head and covers, thus when motor runs at low temperature environment, can silicone oil in rapid heating silicon oil damper by heating equipment, silicone oil is rapidly heated, effectively can solve silicon oil damper when cold-starting, the service life reduction caused greatly because of silicon oil viscosity and vibration damping frequency modulation, the problem that amplitude modulation ability declines.The temperature of silicone oil not only can raise by engine shaft system vibration damping equipment that the utility model provides fast, strengthen frequency modulation, the amplitude modulation ability of silicon oil damper, be conducive to the torsional oscillation situation improving axle system, be conducive to the life-span extending silicon oil damper simultaneously, and structure is simple, reliability is strong, space flexible arrangement, wide adaptability.
Be provided with boss because described motor head covers, the outward edge of described thermal shield is fixedly installed on described boss by fastening piece, thus fixes thermal shield by fastening piece, and not only structure is simple, easy installation and removal, and cost is low.
Outward edge due to described thermal shield is distributed with some radiation holes, when after engine stop motion, by radiation hole, silicon oil damper can be dispelled the heat rapidly, extend the working life of silicon oil damper.
Because described heating equipment is electromagnetic induction heater, adopt electromagnetic induction heater heating silicone oil, can silicone oil be made rapidly to heat up, energy-efficient.
