Description
Technical field:
The utility model relates to a kind of speed change gear, relate in particular to a kind of main axle hydraulic pressure speed change gear.
Background technique:
The main shaft speed change of large-scale radial drilling machine adopts mechanical hand gear usually, and automaticity is lower, has increased operator's labor intensity, and efficient is lower, and gear wear is fast, existing in prior technology deficiency that Here it is.
Summary of the invention:
The purpose of this utility model, be exactly at the existing in prior technology deficiency, a kind of technological scheme of main axle hydraulic pressure speed change gear is provided, this scheme realizes the speed change of main shaft with hydraulic driving, improved manufacturing efficiency greatly, reduce operator's labor intensity, effectively reduced the wearing and tearing of gear.
This programme is realized by following technical measures: this main axle hydraulic pressure speed change gear, comprise headstock, be bearing in axle I and the axle II in the headstock and be fixed on gear I and gear II on the I by bearing, be characterized on the described axle II gear III and duplicate gear being housed, outside the described headstock, be fixed with oil cylinder with axle II coaxial direction, the oil cylinder internal fixation has spool, passed pull bar in the spool, the pull bar upper end is connected on the spool by bearing I I, the lower end of pull bar is connected with duplicate gear by straight pin, side at described oil cylinder, the upside and the downside at pull bar supporting position have oil pipe I and oil pipe II, radially porose between described duplicate gear two gears, in this hole, steel ball is arranged, steel ball has the location collar that is mated outward, described spool upper end is connected with valve gap, the lower end is connected with valve pocket, and there is screw plug described oil cylinder upper end, between described pull bar and the axle II pull bar supporting is arranged.
The beneficial effect of this programme can be learnt according to the narration to such scheme, because in this scheme, on the axle II gear III and duplicate gear are housed, outside the described headstock, be fixed with oil cylinder with axle II coaxial direction, the oil cylinder internal fixation has spool, passed pull bar in the spool, the pull bar upper end is connected on the spool by bearing I I, the lower end of pull bar is connected with duplicate gear by straight pin, side at described oil cylinder, the upside and the downside at pull bar supporting position have oil pipe I and oil pipe II, this structure has realized the hydraulic driving of main shaft speed change, utilize hydraulic oil to drive pull bar and move up and down, thereby drive duplicate gear move up and down with main shaft on different gear engagement.This shows that the utility model compared with prior art has substantive distinguishing features and progress, the beneficial effect of its enforcement also is conspicuous.
Description of drawings:
