Abstract

The utility model relates to a diesel engine starter. A winding shaft is installed between two side walls of a housing case, and a coil spring is installed on the winding shaft. A starting gear is installed on the winding shaft, and a primary winding gear is engaged in the housing case on the starting gear. A ratchet wheel is installed on a primary winding shaft outside the housing case, and a pawl is engaged on the ratchet wheel on the outer side of a supporting sheath. A starting handle is installed at the outer end of the pawl, and a restoring spring is installed between the starting handle and the primary winding shaft. A taper pin is installed on the outer side of the ratchet wheel on the primary winding shaft, and a starting shaft is installed in a winding shaft hole. A driving clutch gear is installed on the starting shaft outside the inner side of the housing case, and a pressure spring is installed in a shaft hole on the starting shaft. A shaft ratchet wheel is arranged on the starting shaft at the inner end of the pressure spring, and a shaft sleeve ratchet wheel is arranged in the winding shaft hole corresponding to the shaft ratchet wheel. A driven clutch gear is arranged on a diesel engine shaft corresponding to the inner end of the starting shaft. The diesel engine starter has the advantages of simple structure, safety and reliability and can automatically separate after starting.

Description

A kind of starter of diesel engine

Technical field:

The utility model relates to motor, particularly a kind of starter of diesel engine that is used for DENG startup usefulness.

Background technique:

The starting drive of existing DENG has two kinds, and a kind of is to be wrapped on the starting shaft of motor with stay cord, drives motor with hand wrench rope and begins rotation, reaches the purpose of startup.Another kind of with exempting to draw the starter starting.The former shortcoming is to start effort, and winter starting is difficulty relatively; The latter with exempt to draw start exist do not separate, under the diesel engine high speed rotating, exempt to draw and then work of starter, easy damage, be not durable.

Summary of the invention:

The purpose of the utility model provides a kind of simple in structure, and cost is low, can separate automatically after the startup, safe and reliable starter of diesel engine.

The technological scheme of the utility model is accomplished as follows, and it includes a casing, it is characterized in that: a spool is installed between the two side of casing; A wind spring is installed in casing on the spool; On the spool in the wind spring outside, a starter receiver is installed, at the beginning of in casing, being engaged with one on the starter receiver around gear, just around a ratchet is installed outside casing on the axle; A supporting sleeve just is installed around the periphery of axle on the casing outer wall; On the ratchet of the outside of supporting sleeve, be engaged with a ratchet, with fixing pin a starting handle be installed, at starting handle and a Returnning spring just is installed on the fixing pin between the axle in the outer end of ratchet; A taper pin is installed outside the ratchet on axle just; In spool, be provided with an axis hole, between axis hole inner casing two side, be equipped with one and start axle, an initiatively clutch gear is installed on the startup axle of outside, casing inboard along central axis; Start axle a stage clip upward is installed in axis hole; On the starting shaft of stage clip inner end, be provided with an axle ratchet, with the corresponding spool of axle ratchet hole in be provided with the axle sleeve ratchet, on the diesel oil arbor corresponding, be furnished with a passive clutch gear with starting the axle inner end.The utlity model has simple in structure, can separate automatically after starting, safe and reliable advantage.

Description of drawings:

Fig. 1 is the structural representation of the utility model; Fig. 2 is the mounting structure schematic representation of casing outside starting handle; Fig. 3 is the structural representation of passive clutch gear.

Embodiment:

The utility model is with pedestal 8 spool 11 to be installed between the two side in a casing 6; A wind spring 7 is being installed in casing on the spool; The outside of wind spring is equipped with a starter receiver 15 on spool, starter receiver one side is engaged with one in casing at the beginning of, around gear 5, just stretches out the casing outer wall around axle 2 ratchet 3 is installed; A supporting sleeve 4 just is installed around the periphery of axle on the casing outer wall; On the ratchet in the supporting sleeve outside, be engaged with a ratchet 18, with fixing pin 19 starting handle 20 be installed, a Returnning spring 21 is installed on the fixing pin between the axle at starting handle and first in the outer end of ratchet; The ratchet outside first a taper pin 1 is installed on axle; In spool, be provided with an axis hole along central axis, the outside is equipped with a starting shaft 10 through axis hole from the casing inboard to casing, and one end stretches out casing an initiatively clutch gear 9 is installed in the inboard of starting shaft; Starting shaft is hexagonal shaped; In the outer end of hexagonal shaped starting shaft a handwheel 16 is installed outside casing, a stage clip 14 is installed on the starting shaft in the spool hole, in the spool hole, be fixed with an axle ratchet 13 on the starting shaft of stage clip inner end; Between spool hole inner reel and shaft hole inner wall, be provided with the axle sleeve ratchet 12 that cooperates with the axle ratchet, on diesel engine, be provided with a passive clutch gear 17 that cooperates with the active clutch gear.

The working principle of the utility model is to be enclosed within just on axle, when manual work turns clockwise energy storage with crank during startup; The rotation that is slidingly matched of ratchet and ratchet drives just and rotates around gear, and starter receiver is rotated counterclockwise; Make the spool band wind spring and rotate energy storage, when treating that wind spring takes up crank is extracted out, under the effect of wind spring, ratchet is rotated counterclockwise; At this moment ratchet heads on ratchet ratchet can not be rotated counterclockwise, and guarantees safety.Twisting handwheel then turns clockwise; Advances turns clockwise to make active clutch gear and passive clutch gear be slidingly matched firmly; Remaining binding site under the effect of startup axle at stage clip under the diesel engine state of rest, can only turn clockwise, at this moment depress starting handle and make it to separate with ratchet; The diesel engine starting back as ready that gets up often is become a full member, separate with passive clutch gear with the active clutch gear on starting spool.
