Abstract
The utility model discloses a self-propelled combine harvester synchronizer, which mainly comprises a toothed hub (1) and a toothed sleeve (2), the toothed sleeve (2) is sleeved on the outer surface of the toothed hub (1), two shafts of a gearbox are inserted into the inner circle of the toothed hub (1), and the surface of the inner circle of the toothed hub (1) is provided with eight rectangular splines (4), which are connected with the two shafts of the gearbox. The synchronizer provided by the utility model can effectively prevent the throw-out of gear, and has the advantages of short synchronizing time, no impact, energy saving, consumption reduction, environment-friendliness and emission reduction.
Description
Technical field
The utility model relates to a kind of self-propelled combine synchronized.
Background technology
Present domestic maize harvesting machine mainly is to be the backpack type of power with the large and middle tractor, self-propelled type still is in the beginning developing stage, similar gearbox product transmission system is pure mechanical slip gear gearshift form, and gear, bearing loading capability are not high, the gearshift poor-performing.The D5 synchronized is used in the self-propelled combine gearbox of feed quantity 5KG/S, and high to low gear adopts the synchronizer sleeve structure, light and flexible when making gear shift, and good hand touch, nothing are impacted.
Summary of the invention
The utility model provides a kind of self-propelled combine synchronized, effectively prevents off-gear, and lock in time is short, does not have impact, energy-saving and cost-reducing, environmental emission reduction.
The utility model has adopted following technical scheme: a kind of self-propelled combine synchronized, it mainly comprises tooth hub and tooth cover, the tooth cover is enclosed within on the outer surface of tooth hub, two of gearbox penetrate in the inner ring of tooth hub, described tooth hub inner peripheral surface is provided with 8 rectangular spline teeth groove, and two of described rectangular spline teeth groove and gearbox link.
The outer surface of described tooth hub is provided with 34 standard involute spline teeth, is provided with spline in the inner ring of described tooth cover, and spline is slidingly matched in the standard involute spline tooth of described tooth hub outer surface and the tooth cover inner ring; Be provided with dead slot in the described tooth cover; The material of described tooth hub and tooth cover is the 20CrMnTi structural alloy steel; The outer surface of described tooth cover is provided with fork slot; Described tooth hub and tooth cover adopt the engagement nested structure.
The utlity model has following beneficial effect: establish a dead slot in the tooth cover of the present utility model, and spline tooth is established the negative awl of 4 degree, processing 100 degree herringbone angle designs, light and flexible when not only making gearshift, good hand touch do not have to be impacted, off-gear not, lock in time short, fuel oil the high characteristics of economy, improved the bearing capacity of gearbox gear, axle simultaneously, product safety is reliable.This project is characteristics innovative design and the application according to lock ring type synchronized engagement gearshift, meet the standardized designs requirement, noise is big, easy to wear when improving the gearshift of grain header existing mechanical shifting slide gear, defectives such as engage a gear is dumb, prolong product service life, reduced the use maintenance cost, improve comfortableness, the environmental emission reduction driven, have simple in structurely, be suitable for mass production.The utility model tooth hub and tooth cover are steel alloy 20CrMnTi material, can improve the intensity of tooth hub and tooth cover like this.
