Description
Technical field
The present invention relates to motor starting drive, specifically a kind of structure simple, start reliable, simple to operate safely, be automatically found put-put or air-cooled diesel engine manual cranking device that engine start opens initial point and long working life low to motor fanout free region, user cost.
Background technique
The put-put of prior art and miniature diesel engine starting drive have the starting drive of following three kinds of startup types.The first is Manual starting device, and the starting drive cost of the type is low, but wastes time and energy, and starts success rate low; The second is electric starting device, and the starting drive startup of the type is simple, but its user cost is high, and maintenance cost is high and engine start cannot be found to open initial point to starting drive injury greatly, also large to motor injury; The third is manual cranking device, and the starting drive of the type starts simply, efficiently convenient, but due to itself structure, engine start cannot be found to open initial point, make its to motor and the injury of starting drive own large, working life is short.
The manual cranking device of prior art generally comprises central shaft, running shaft is on center shaft installed, one end of running shaft is connected with gearwheel and ratchet by flat key, gearwheel and ratchet are arranged in the installation cavity that outer cover and plate washer are formed, the small gear engaged with gearwheel, the gear shaft of small gear passes the base plate of outer cover, and ratchet engages with the ratchet be fixed on outer cover base plate outer wall; On termination, be provided with telescopic claw assembly after the other end of running shaft passes plate washer, telescopic claw assembly is positioned at engine start cover, and the telescopic claw of telescopic claw assembly mates with the actuating hole on engine start cover sidewall; The shaft part being arranged in the running shaft of the installation cavity that outer cover and plate washer are formed is provided with clockwork spring, and one end of this clockwork spring is tight against on the rotary shaft, and one end is fixed on outer cover inwall in addition.During use, driven the bull gear drive engaged with small gear by handle control gear axle, gearwheel driven rotary axle rotates and tightens up clockwork spring; Running shaft drives telescopic claw assembly to be rotated counterclockwise, and telescopic claw assembly and engine start cover leave; Then the control arm moving ratchet makes ratchet and ratchet depart from, running shaft rotates under clockwork spring reset response power, telescopic claw assembly is driven to rotate, drive engine start cover to rotate in the actuating hole making the telescopic claw of telescopic claw assembly stretch on engine start cover sidewall, engine start cover drives the flywheel of motor to rotate and realizes ato unit.This structural priming simply, efficiently convenient, but due to engine start cannot be found to open initial point, its to motor and the injury of starting drive own large, working life is short.
The technological scheme announced in Chinese patent 201420206345.8 solves the technical problem that the startup of above-mentioned manual cranking device is wasted time and energy, large to motor injury, user cost is high and working life is short to a certain extent.But the shortcoming in use existed is: start and impact relatively large, to motor still old injury necessarily, start-up operation is dangerous, maintenance difficult and dangerous.This structure needs so to find startup to open initial point, but needing workman to have a special action to go for seek god opens initial point, looks for trouble, wastes time and energy, and exists and operate insecurity.
In sum, the shortcoming that the put-put of prior art and miniature diesel engine starting drive exist is: start waste time and energy, cannot automatically look for startup open initial point and large to motor injury, user cost is high, working life is short, the dangerous and maintenance difficult of start-up operation and dangerous.
