Description
Technical field
This utility model relates to field, particularly relates to a kind of built-up crankshaft gear。
Background technology
Bent axle is one of generating set critical part, and its effect is to export in the way of gyration after cylinder work done being collected, and crankshaft toothed wheel is installed in gear or the key gear of crankshaft front end, is commonly used to for moving cam shaft gear, chain or toothed belt。
Where no matter traditional gear, be arranged on, and its structure is integral structure。Owing to crankshaft structure is sometimes more changeable, the overall structure of bent axle is stronger, is arranged on the gear on bent axle once install and disassembling relatively more difficult, after the gear being arranged on bent axle is damaged, and the more difficult replacing of gear。
Summary of the invention
This utility model is mainly solving the technical problems that provide a kind of built-up crankshaft gear, it is possible to be conveniently replaceable tooth bar, sound construction, saves cost, safe and reliable。
For solving above-mentioned technical problem, the technical scheme that this utility model adopts is: provide a kind of built-up crankshaft gear, including: toothed disc and tooth bar dish, described toothed disc is provided with mounting groove, described tooth bar dish has clamping projection, described clamping male cooperation is arranged on mounting groove, described toothed disc is provided with multiple fastening stud, the both sides up and down of described fastening stud have been movably connected with top board and lower platen, described top board and lower platen and toothed disc and tooth bar dish have been compressed by fastening stud。
In one preferred embodiment of this utility model, the quantity of described fastening stud is 2, and described fastening stud is symmetricly set on toothed disc。
In one preferred embodiment of this utility model, described top board and lower platen are the middle circular sheet in hollow form, described top board and lower platen and toothed disc and tooth bar dish are compressed by the clamp nut being arranged on fastening stud。
In one preferred embodiment of this utility model, described mounting groove is annular mounting groove, offers the surface putting toothed disc。
In one preferred embodiment of this utility model, described toothed disc is provided with multiple lightening hole。
The beneficial effects of the utility model are: this utility model built-up crankshaft gear, it is possible to be conveniently replaceable tooth bar, sound construction, save cost, safe and reliable。
