Abstract
The utility model discloses a cam shaft gear, which comprises a hub, a flange, a mounting shaft hole, gear teeth, a spoke and a positioning threaded hole, wherein the flange is arranged on the edge of the spoke; the flange is provided with the gear teeth; the spoke is raised outwards; the hub is arranged at the central position of the spoke; the mounting shaft hole is formed in the center of the hub; the hub is provided with a weight removing hole and the positioning threaded hole; and the inner wall of the mounting shaft hole is provided with a circle of limiting grooves in the circumferential direction. The cam shaft gear has low loads and high shock resistance and is driven stably.
Description
Technical field
The utility model relates to a kind of camshaft gear wheel.
Background technique
Gear is the intermeshing mechanical parts that tooth is arranged of ability, and the application of gear in transmission occurred very early.In 19 end of the centurys, generate cutting ratio juris and utilize the appearance in succession of the special purpose machine tool and the cutter of this principle cutting is along with the development of producing; The stationarity of gear operation comes into one's own, and camshaft timing gear also uses extensively now, and there is Heavy Weight in traditional cam axle timing gear; Install inconvenient; And exist noise big, and Heavy Weight cause transmission efficiency low, defective such as working life is short.
The model utility content
That the utility model provides that negative load is little in a kind of transmission process, anti-seismic performance is good, stable transmission camshaft gear wheel.
The utility model technical solution problem provides following scheme:
A kind of camshaft gear wheel; Comprise wheel hub, wheel rim, installation axle hole, the gear teeth, spoke, positioning spiro pit, said spoke edge is a wheel rim, establishes the gear teeth on the said wheel rim; Said spoke outwards swells; Said spoke central position is a wheel hub, and said wheel hub center is an installation axle hole, establishes repeated hole and positioning spiro pit on the said wheel hub.
The inwall upper edge of said installation axle hole is circumferentially with a circle restraining groove.
The utility model is fixed on gear and axle assembling on the axle, and is installed in the gear chamber, when bent axle drives the piston operation; Through crankshaft gear and train, wheel shaft drive inlet and exhaust valve and distributor corresponding with each stroke of motion of piston, with the normal operation of assurance motor, it is little to be contained in the motor operational vibration; Noise is low, compact structure, and transmission efficiency is high; Long service life, interchangeability is good, and the client is generally reflected assembling and easy to maintenance.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Referring to accompanying drawing, a kind of camshaft gear wheel comprises wheel hub 1, wheel rim 2, installation axle hole 3, the gear teeth 4, spoke 5, positioning spiro pit 6; Said spoke 5 edges are wheel rim 2, establish the gear teeth 4 on the said wheel rim 2, and said spoke 5 outwards swells; Said spoke 5 central positions are wheel hub 1; Said wheel hub 1 center is an installation axle hole 3, establishes repeated hole 7 and positioning spiro pit 6 on the said wheel hub 1, and the inwall upper edge of said installation axle hole 3 is circumferentially with a circle restraining groove 8.
Claims (2)
1. camshaft gear wheel; Comprise wheel hub, wheel rim, installation axle hole, the gear teeth, spoke, positioning spiro pit, said spoke edge is a wheel rim, establishes the gear teeth on the said wheel rim; Said spoke outwards swells; Said spoke central position is a wheel hub, and said wheel hub center is an installation axle hole, it is characterized in that: establish repeated hole and positioning spiro pit on the said wheel hub.
