Abstract
The utility model discloses a synchronizer of a harvester, which mainly comprises a gear hub (1) and a gear sleeve (2); the gear sleeve (2) is sheathed on the outer surface of the gear hub (1), a transmission shaft penetrates through an inner ring of the gear hub (1), and the surface of the inner ring of the gear hub (1) is provided with a standard involute spline gear which is connected with the transmission shaft in a matching way. The synchronizer not only can enhance the intensity of the connection, but also can improve torque bearing capacity of the transmission shaft, and effectively prevent the breakage of the transmission shaft.
Description
Technical field
The utility model relates to a kind of harvester synchronizer.
Background technology
Need often shifted during combine work; and the different upper and lower level travelling gear of rotating speed is difficult to inserting engagement to realize speed change; this just needs a kind of synchronized to make upper and lower level travelling gear rotary speed be tending towards approaching, so that gears engaged realizes transmission gear shift.The D2.8G synchronized is applied to the problem that the grain header gearbox has solved walking speed change buty shifting well; But because the complexity of harvester operation condition, make shifted very frequently, it is loosening that synchromesh gear hub and propeller shaft couplings often take place, the phenomenon of while drive shafts fracture.
Summary of the invention
The utility model provides a kind of harvester synchronizer, and it not only can strengthen the intensity when connecting, and can improve the moment of torsion bearing capacity of power transmission shaft, has effectively prevented the fracture of power transmission shaft.
The utility model has adopted following technical scheme: a kind of harvester synchronizer, it mainly comprises tooth hub and tooth cover, the tooth cover is enclosed within on the outer surface of tooth hub, and power transmission shaft penetrates in the inner ring of tooth hub, and the inner peripheral surface of described tooth hub has the connection that matches with power transmission shaft of standard involute spline tooth.
Described standard involute spline profile of tooth is 42 slot standard involute spline teeth.Described tooth hub is circular, and the end face of tooth hub is a planar structure.Described tooth hub is a structural alloy steel 20GrMnTi material.Described tooth cover inner ring is provided with 30 standard involute spline teeth groove, and the outer surface that overlaps at tooth is provided with fork slot.Described tooth cover is structural alloy steel 20GrMnTi material.
The utlity model has following beneficial effect: the utility model tooth hub inner peripheral surface has 42 slot standard involute spline teeth, so not only can strengthen tooth hub and propeller shaft couplings intensity, and make the power transmission shaft that matches increase effective sectional area, improved the torque transmission shaft bearing capacity, thereby effectively prevented the fracture of power transmission shaft, it meets the requirement of standardized designs simultaneously, control light flexibly, safe and reliable, make maintain and replace very efficient and convenient, use and maintenance cost thereby greatly reduce.The end face of the utility model tooth hub is the plane, can simplify the processing technology of tooth hub like this.The utility model tooth hub and tooth cover are structural alloy steel 20GrMnTi material, can improve the intensity of tooth hub and tooth cover like this.
