MISSION CASE OF AGRICULTURAL POWER MACHINE

摘要

PURPOSE:To easily carry out maintenance work and assembly work by dividing a case shell body in which an input shaft, a running output shaft, a clutch shaft and an operating output shaft are disposed mutually in parallel with one another on a division plane intersecting with the respective intermediate parts of the shafts. CONSTITUTION:The rotation output of an engine is transmitted to a front part by a transmission shaft 23 and transmitted to the input shaft 25 of a mission case 5 through a transmission gear 24 operating as a clutch and a sub- transmission at the front end of the transmission shaft 23. The mission case 5 consists of case core bodies 5a, 5b divided to half at front and back parts which are connected by means of a bolt or the like. An input shaft 25, a running output shaft 34, a clutch shaft 35 and an operating output shaft 36 are supported mutually in parallel with one another in forward and backward directions therein. A main transmission and an intermediate transmission are assembled together and the mission case 5 is constructed as a rational and compact form, the number of parts can be decreased and the case shell body can be divided along a division plane. Thus, assembling maintenance or the like can be easily performed.
