Description

Labour-saving safety hand starter for internal combustion engine

The utility model belongs to internal-combustion engine hand crank starting arrangement, particularly a kind of laborsaving safe internal-combustion engine hand-operated starter.

Many trucies, microtractor are in the sky when cold or in emergency circumstances often will start explosive motor with hand crank.Very painstaking hard when existing hand crank shakes, and, can not ensure operator's safety often owing to the people is injured during engine inversion.Can only do 180 ° of adjustment when existing crank is connected with the motor spindle nose simultaneously, often the angle of crank is in and is not suitable for state firmly, has more increased the difficulty of hand starting.

Laborsaving when the purpose of this utility model provides a kind of shaking, and the laborsaving safe internal-combustion engine hand-operated starter of hurting sb.'s feelings can prevent engine inversion the time.It can adjust the crank angle, is convenient to shake firmly.

The utility model is achieved in that the propeller shaft sleeve that one one end has gear is set that the other end of axle sleeve has internal spline and external splines.An end that has gear is for inner, and its core is thicker axis hole, and interior dress can pass the pressure spring of output driving shaft.The fulcrum of spring collar as pressure spring is equipped with in output driving shaft the inner; The live axle outer end has the internal spline engagement of external splines and axle sleeve outer end.The output end cap is passed in the axle sleeve outer end, its external splines and a ratchet socket, and ratchet claw and spring thereof are loaded on output terminal and cover, and ratchet, ratchet claw, spring constitute the moving device of counter.One circle ball is housed between output end cap and the propeller shaft sleeve, constitutes the shot bearing.The gear of propeller shaft sleeve the inner and a ring gear engagement, ring gear meshes with 5 groups of (10) planet pinions again, and 5 groups of planetary mandrels are loaded on input end and cover, and every group of planetary pinion meshes with ring gear and input drive gear respectively.The input drive gear outer end is passed the input end cap and at the two the shot bearing is housed, and is shaped on spline in the axis hole of input gear.Crank is shaped on and imports the external splines that the gear internal spline cooperates.Input has flange plate with the output terminal cover tape, duct-like pair of mounting flange is set, two end caps and this flange plate bolton between the two.Input end covers supporting frame is housed, and when using this starter supporting frame is supported on the car body.The middle partition is arranged between the gear on input drive gear and the propeller shaft sleeve, and this porose insertion end of crank that makes in distance piece center is passed through.

This hand-operated starter utilizes the gear-shift transmission principle, reaches labour-saving effect when shaking by the rotating speed that dwindles output driving shaft, has alleviated particularly weak driver's labor intensity of operator.When the moving device of the counter of this starter can prevent the anti-fire reversing of motor effectively the people is injured, safe in utilization.Because crank cooperates with feather key with the input gear, the operator can place crank best firmly position.When shaking intermittently, can transfer to the optimum position and continue to shake, for the operator brings great convenience.Crank can take off from starter in time spent not, deposited conveniently.

Among the figure, output driving shaft (1) is inserted in the axis hole of propeller shaft sleeve (3), and holddown spring (7) is equipped with in axis hole the inner, and this spring housing and blocks with the collar on live axle the inner on live axle.Between axle sleeve (3) and the output end cap (6) shot bearing (8) is arranged, the ball of bearing is packed into by the aperture on the end cap (6) and is sealed with screw then.The ratchet claw and the spring of the moving device (5) of counter are loaded on the end cap (6), and ratchet is loaded on the axle sleeve (3), and there is water proof cover (4) end cap (6) outer end, and water proof cover (2) also is stamped in axle sleeve (3) outer end.Ring gear (10) meshes with propeller shaft sleeve (3) and planet pinion (13) respectively, and planetary pinion meshes with input drive gear (14) again, between gear (14), part (3) middle partition (11) is arranged.Between input drive gear (14) and the input end cap (15) shot bearing (8) is arranged, input end cap outer end cap has water proof cover (16).Input end cap (15), output end cap (6) and two mounting flange (12) tighten together with bolt (9).Crank (17) has spline, can insert and extract in the internal spline of input gear (14).Supporting frame (19) is loaded on the input end cap (15).Part (18) is the crank supporting element on the automobile, and (20) are the motor spindle nose.

This starter of the internal-combustion engine is aimed at motor spindle nose (20) with live axle (1) in use, supporting frame (19) support on automobile, crank (17) insert in the starter and support on the crank supporting element (18) of automobile.In starter, promote crank then live axle (1) is ejected, rotate crank live axle and motor spindle nose are pegged graft by shift fork, can shake crank easily to normal working of engine.Finish using and crank can be extracted, the starter volume that crank takes off is very little, is convenient to deposit.
