Abstract

The utility model discloses a gasoline engine crankshaft protecting device which comprises a crankshaft assembly(1), a needle roller bearing(4), driving belt pulley components(5) and a clutch assembly(7), while the driving belt pulley components are arranged on the needle roller bearing(4), and the clutch assembly(7) is fixed on the output end of the crankshaft assembly(1), and a washer is arranged on the crankshaft assembly between the clutch assembly(7) and the driving belt pulley components(5); an isolating mat(2) is arranged inside the bearing guard of the crankshaft assembly(1) and a bushing block(3) is arranged on the bearing guard of the crankshaft assembly(1); the needle roller shaft(4) is arranged on the bushing block(3); the bearing guard of the crankshaft assembly(1) and the bushing block(3), the needle roller shaft(4) and the bushing block(3) are movably matched. The utility model solves the problem that the needle roller shaft(4) abrades the crankshaft assembly(1) and has reasonable structure, also is convenient for processing and has favorable protecting effect and long service life.

Description

The gasoline engine crank protective gear
Technical field
The utility model relates to the protective gear of a kind of protective gear, particularly a kind of gasoline engine crank.
Background technique
Small gasoline mechanomotive force output at present generally is made up of crank assemblby, needle bearing, pulley assembly, clutch assembly, crank assemblby drives the clutch assembly high speed rotating, pulley assembly rotates outputting power at next superhigh speed of clutch assembly effect, and the drive needle bearing rotates relative to crank assemblby; In running, needle bearing directly contacts and relatively rotates and produce mutual friction mutually with bent axle, and through causing crankshaft wear to be scrapped after the long-time running, the working life of petrol engine is short.For this reason, many manufacturers and knowledgeable people have carried out research repeatedly, but do not have ideal method to solve the problems referred to above so far as yet.
Summary of the invention
For overcoming the disadvantage of above-mentioned existence, problem to be solved in the utility model provides a kind of simple and reasonable, easy to process, gasoline engine crank protective gear that protection is effective.
The technological scheme that its technical problem that solves the utility model adopts, it comprises crank assemblby, needle bearing, drive pulley assembly, clutch assembly, the drive pulley assembly is arranged on the needle bearing, clutch assembly is fixed on the output terminal of crank assemblby, crank assemblby is provided with packing ring between clutch assembly and the drive pulley assembly, the bearing guard inboard of described crank assemblby is provided with dottle pin, the bearing guard of crank assemblby is provided with lining, needle bearing is arranged on the lining, and the bearing guard of crank assemblby and lining, needle bearing and lining are movingly.
After the above-mentioned technological scheme that provides is provided, needle bearing rotates relative to lining, it is static relatively that the bearing guard of the relative crank assemblby of lining keeps, therefore in running, needle bearing produces mutual friction mutually with lining and is worn, needle bearing and lining can come into operation after damaging transposing again, do not influence the use of crank assemblby, thereby have protected crank assemblby effectively; Have simple and reasonable, easy to process, characteristics such as protection is effective, long service life.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Shown in Figure 1; specific embodiments for the sliding device of the utility model gasoline engine crank protection; it comprises crank assemblby 1; needle bearing 4; drive pulley assembly 5; clutch assembly 7; drive pulley assembly 5 is arranged on the needle bearing 4; clutch assembly 7 is fixed on the output terminal of crank assemblby 1; crank assemblby 1 is provided with packing ring 6 between clutch assembly 7 and the drive pulley assembly 5; the bearing guard inboard of described crank assemblby 1 is provided with dottle pin 2; the bearing guard of crank assemblby 1 is provided with lining 3; needle bearing 4 is arranged on the lining 3, the bearing guard of crank assemblby 1 and lining 3; needle bearing 4 and lining 3 are movingly.
When petrol engine is worked, crank assemblby 1 and clutch assembly 7 high speed rotating, drive drive pulley assembly 5 high speed rotating outputting power together, and drive needle bearing 4 rotates relative to lining 3 differentials, it is static relatively that the bearing guard of lining 3 relative crank assemblbies 1 keeps, and therefore in running, needle bearing 4 produces mutual friction mutually and produces wearing and tearing with lining 3, lining 3 is minimum with the bearing guard wearing and tearing of crank assemblby 1, can not consider wear extent basically; After needle bearing 4 or lining 3 damages, only need change needle bearing 4 or lining 3 again, can drop into normal use, do not influence the use of crank assemblby 1, protect crank assemblby 1 effectively, thereby prolonged the working life of petrol engine.
