Abstract
The utility model provides a gearbox of walking at a slow speed belongs to the technical field of farm machinery or engineering machinery, is including main variable speed axle, jackshaft and steering spindle, its characterized in that owner change speed epaxial be equipped with with the I main drive driving gear that the gear slided simultaneously that reverses gear, be equipped with jackshaft gear wheel and jackshaft pinion on the jackshaft, be equipped with the main drive gear wheel in the steering spindle. The utility model discloses a main drive driving gear that slides and the speed reduction of jackshaft design has increased the drive ratio, and jogging speed can reach 5mmin, be applicable to very much the mechanism that traveling speed is low, and simple structure is reliable.
Description
Technical field
The utility model belongs to the technical field of farm machinery or engineering machinery, is specifically related to a kind of gearbox of low-speed running.
Background technique
Due to farm machine and the extensive use of mine locating machine, require that the minimum speed of traveller controls at about 5km/h, the speed of existing gearbox is all very fast, cannot meet this requirement, and not only cost is high but also structure is also unreasonable to increase gear in addition.
Model utility content
For problems of the prior art, the utility model object is the technological scheme providing a kind of slow-speed drive.
A kind of low-speed running gearbox, comprise main variable speed shaft, jack shaft and steering shaft, it is characterized in that main variable speed shaft is provided with the central transmission driving gear with the slippage simultaneously of I reverse gear, jack shaft is provided with jack shaft gearwheel and jack shaft small gear, and steering shaft is provided with central transmission gearwheel.
Described low-speed running gearbox, is characterized in that central transmission driving gear that the is described and slippage simultaneously of I reverse gear by transmission of power to jack shaft gearwheel, then by jack shaft small gear by transmission of power to central transmission gearwheel.
Described low-speed running gearbox, is characterized in that with the central transmission driving gear of I reverse gear slippage simultaneously and I reverse gear be an one-piece parts.
Described low-speed running gearbox, is characterized in that jack shaft is splined shaft.
Described low-speed running gearbox, is characterized in that the number of teeth of central transmission gearwheel is: 37-48 tooth.
The utility model adopts the deceleration design of the central transmission driving gear of slippage and jack shaft, increases velocity ratio, and most jogging speed can reach 5m/min, is highly suitable for the mechanism that the speed of travel is low, and simple and reliable for structure.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
The utility model is further illustrated below in conjunction with Figure of description.
A kind of low-speed running gearbox, comprise main variable speed shaft 1, jack shaft 2 and steering shaft 3, main variable speed shaft 1 is provided with the central transmission driving gear 5 with the slippage simultaneously of I reverse gear 4, and are one-piece parts with the central transmission driving gear 5 of I reverse gear 4 simultaneously slippage and I reverse gear 4, indivisible, and slippage on main variable speed shaft 1.Jack shaft 2 is provided with jack shaft gearwheel 6 and jack shaft small gear 7, and jack shaft 2 is for splined shaft and for ensureing that jack shaft gearwheel 6 and jack shaft small gear 7 can rotate in the same way simultaneously, steering shaft 3 is provided with central transmission gearwheel 8, with the central transmission driving gear 5 of I reverse gear 4 simultaneously slippage by transmission of power to jack shaft gearwheel 6, again by jack shaft small gear 7 by transmission of power to central transmission gearwheel 8, central transmission gearwheel 8 passes to output mechanism again, and the number of teeth of central transmission gearwheel 8 is preferably 37-48 tooth.
When existing gearbox designs does not do great change, effectively utilize said structure to increase velocity ratio, realize the object of farm machinery or engineering machinery low-speed running, reliable and stable!
