Summary of the invention

The purpose of this utility model provides the diesel engine swinging-free starter of a kind of reliable performance, long service life.

For achieving the above object, the utility model adopts following technological scheme: a kind of diesel engine swinging-free starter, comprise casing and be contained in casing interior transmission device, clutch, whirlpool spring mechanism, the mechanism of decompressor and time movement, described transmission device comprises gearing device, driving gear, driven gear and square chest one-way wheel, the driving gear axis hole is arranged and just around axis hole on the gearing device, the driving cog race is arranged on the gearing device, driving gear is contained in the driving cog race, driven gear and square chest one-way wheel all are contained in first on axle, and driven gear and driving gear intermesh.

The mechanism of decompressor comprises decompression handle, decompression shaft and decompression push rod, decompression shaft is contained on the casing and its end is positioned at outside the casing, decompression handle is contained in the end of decompression shaft, the middle part of decompression push rod is hinged on the casing, the top of decompression push rod is one section straight-bar, the bottom of decompression push rod is fixed with one section fork, the tip of fork can contact with the timing shifting block on the timing wheel, the mechanism of decompressor also comprises the decompression pull bar, one end of decompression pull bar links to each other with square chest top, the other end of decompression pull bar links to each other with decompression shaft, and the middle part of decompression shaft is a cam face, and the straight-bar on decompression push rod top contacts with the middle part of decompression shaft.

Decompression pull bar and square chest top is for flexibly connecting, and is connected for hinge between reduce pressure pull bar and the decompression shaft.

Adopt the diesel engine swinging-free starter of technique scheme; replaced original square chest by gearing device; gearing device can be by the mould once-through; easy to make and precision is easy to control; and bearings mounted space is arranged on the gearing device; just in axle is contained in bearing hole, can effectively protect gearing device and casing, thereby prolong the working life of complete machine.
