Abstract
Disclosed is a crankshaft timing gear. A plurality of de-weighting holes are uniformly distributed around the shaft hole in the end face of the crankshaft timing gear; a plurality of location holes are arranged between the de-weighting holes; and mark teeth are arranged among the gear teeth of the crankshaft timing gear. When the crankshaft timing gear is in use, the gear and the shaft are assembled by fixing the gear to the shaft and installed inside a gear chamber. When the crankshaft drives a piston to operate, via the crankshaft timing gear and the gear train, an axle drives an inlet-outlet valve and a distributor block to correspond to every motion stroke of the piston, thus to ensure the normal operation of an engine. The crankshaft timing gear features high precision, weak working vibration when installed inside an engine, low noise, compact structure, high transmission efficiency, and long service lifetime.
Description
Technical field
The utility model relates to a kind of crankshaft timing gear.
Background technique
Gear is the intermeshing mechanical parts that tooth is arranged of energy, and the application of gear in transmission occurred very early.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, along with the development of producing, the stationarity of gear operation comes into one's own, there is Heavy Weight in traditional crankshaft timing gear, inconvenience is installed, and exists noise big, defectives such as and Heavy Weight causes transmission efficiency low, and working life is short.
The model utility content
The utility model provides a kind of operational vibration that is contained in the motor little, and noise is low, compact structure, and the transmission efficiency height, long service life, interchangeability is good, assembling and crankshaft timing gear easy to maintenance.
The utility model technical solution problem provides following scheme:
A kind of crankshaft timing gear is distributed with several around the end face upper shaft hole of described gear and removes repeated hole, and described several remove to be distributed with between the repeated hole several positioning holes, are provided with notch in the gear teeth of described gear.
The utility model gear has several to remove repeated hole, can alleviate the weight of gear, make the load of machine in operation process little, vibrate little, during use gear and axle assembling, be fixed on the axle, be installed in the gear chamber, when bent axle drives the piston operation, by crankshaft timing gear and train, wheel shaft driving inlet and exhaust valve and distributor are corresponding with each stroke of motion of piston, to guarantee the normal operation of motor.
The utility model precision height, it is little to be contained in the motor operational vibration, and noise is low, compact structure, the transmission efficiency height, long service life, interchangeability is good, assembling and easy to maintenance.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Referring to accompanying drawing, a kind of crankshaft timing gear is distributed with several around the end face upper shaft hole 2 of described gear 1 and removes repeated hole 3, and described several remove to be distributed with between the repeated hole 3 several positioning holes 4, are provided with notch 6 in the gear teeth 5 of described gear 1.
Claims (1)
1. a crankshaft timing gear comprises axis hole, the gear teeth, it is characterized in that: be distributed with several around the end face upper shaft hole of described gear and remove repeated hole, described several remove to be distributed with between the repeated hole several positioning holes, are provided with notch in the gear teeth of described gear.
