Abstract
The utility model disclose a small scale gas motor matched clutch, which comprises a clutch claw fixing plate, a clutch claw, a rivet, a shell, a set collar, an anti-shock collar, a spring, and an output shaft. The anti-shock collar is arranged at connecting part of two ends of two clutch claws. A connecting part of two clutch claws and the clutch claw fixing plate is fixed by the rivet. Two clutch claws are provided with a lug boss at an inner end. A lug boss drill is provided with a spring hole. Two clutch claws are strengthened by the spring. A middle part of an outer collar of two clutch claws is cast with friction materials. The set collar is arranged between the shell and the clutch claw fixing plate. The output shaft of the gas motor is put through the clutch claw fixing plate, the set collar, and the shell and is screwed down by a nut. The utility model has advantages of a simple and reasonable structure, an easy installation, an unloaded start, a reduced start force, a prolonged service life and an expanded operation range of small scaled gas motors in an area of agricultural machinery.
Description
The utility model belongs to clutch, the supporting clutch of particularly a kind of miniature gasoline engine.
Existing commercially available miniature gasoline engine does not all have supporting clutch device, starting under load is difficulty very, must reach bigger pulling force and higher pulling rotating speed could start, the starting stay cord is than easy-rupturing, labor intensity is big when starting in a word, require height, common people are difficult to reach requirement, thereby has influenced promoting the use of of miniature gasoline engine.
The purpose of this utility model is to provide a kind of simple installation, not starting under load, minimizing starting pulling force, the supporting clutch of the miniature gasoline engine that increases the service life.
Technical solution of the present utility model is such, comprise by clutch pawl fixed plate, the clutch pawl, rivet, shell, spacer ring, bump protection ring, spring, output shaft, bump protection ring is equipped with in the jointing place, two ends of two clutch pawls, one end of two clutch pawls has attachment hole, the hole of the corresponding clutch pawl of rivet hole is opened at clutch pawl fixed plate two ends, and tighten up with rivet, clutch pawl fixed plate center has output shaft hole, there is boss two clutch pawl the inners, boss is drilled with spring eye, with two clutch pawls of spring tension, two clutch pawl outer ring intermediate portions have cemented abrasives, between the bearing of shell and the clutch pawl fixed plate spacer ring is arranged, output shaft of gasoline engine passes clutch pawl fixed plate, spacer ring, use nut screwing clamping behind the shell.
The utility model has the advantages that simple and reasonable, simple installation, not starting under load, minimizing starting pulling force, increase the service life, widened the using scope of miniature gasoline engine aspect farm machinery, can be widely used on the miniature farm machineries such as threshing machine, suction engine, rice milling machine, shredder, it is continuous to reach the clutch smooth working.
Below in conjunction with drawings and Examples to the utility model further instruction.
Fig. 1 is that overall structure of the present utility model is installed sectional view.
Fig. 2 is that clutch configuration of the present utility model is installed plan view.
Fig. 3 is a clutch pawl fixed plate part plan view of the present utility model.

Fig. 6 is a casing part sectional view of the present utility model.
Fig. 7 is a spacer ring part sectional view of the present utility model.
Among Fig. 1～Fig. 7, clutch pawl fixed plate (1), clutch pawl (2), rivet (3), shell (4), back-up ring (5), bearing (6), nut (7), packing ring (8), spacer ring (9), bump protection ring (10), output shaft (11), petrol engine axle sleeve (12), spring (13), output shaft hole (14), rivet hole (15), attachment hole (16), boss (17), spring eye (18), abrasives (19).
Most preferred embodiment of the present utility model is such, referring to figs. 1 through shown in Figure 7, two clutch pawls (2) are die casting aluminium manufacturing and bonding the forming of abrasives (19), under action of centrifugal force, drive shell (4) transferring power, shell (4) adds with the punching press of A3 plate and is welded, clutch pawl fixed plate (1) is stamped to form with the A3 plate, bump protection ring (10) is equipped with in the jointing place, two ends of two clutch pawls (2), play the interlock antihunt action, one end of two clutch pawls (2) has attachment hole (16), clutch pawl fixed plate (1) two ends have the attachment hole (16) of the corresponding clutch pawl of rivet hole (15) (2), and tighten up with rivet (3), clutch pawl fixed plate (1) center has output shaft hole (14), there is boss (17) two clutch pawls (2) the inner, boss (17) is drilled with spring eye (18), with spring (13) tension two clutch pawls (2), two clutch pawls (2) outer ring intermediate portion has cemented abrasives (19), between the bearing (6) of shell (4) and the clutch pawl fixed plate (1) spacer ring (9) is arranged, spacer ring (9) acts on axially locating, and output shaft of gasoline engine (11) passes clutch pawl fixed plate (1), spacer ring (9), shell (4) back packing ring (8), nut (7) is tightened.Working principle of the present utility model is such, when starting, because rotating speed is lower, rotating speed is passed to the pulling force of the radial centrifugal force of two clutch pawls (2) less than spring (13), at this moment clutch pawl (2) separates with shell (4) internal surface, so starting the time is an on-load not, the starting back is along with the increase of petrol engine rotational speed, the also corresponding increase of the radial centrifugal force of clutch pawl (2), up to the pulling force that overcomes spring (13), make the abrasives (19) of two clutch pawls (2) have certain pressure to contact with shell (4) internal surface, the rotation that drives shell (4) like this under the effect of friction comes transferring power, and it is continuous to reach the clutch smooth working.
