The invention relates to mobile agricultural machines, in particular to V-belt speed variators.

The purpose of the invention is to increase the durability of the variator,

The V-belt speed variator comprises a housing 1. a drive 2 and a driven 3 shafts installed therein, a drive 4, a driven 5 and an intermediate 6 pulleys, a drive A and a driven 5 pulleys are mounted respectively on the driving 2 and driven 3 shafts, a swing bearing 7 mounted at one end 8 pivotally in the housing 1. a fastening element 9 located on the second end of the swinging support 7. An intermediate shaft 10 with bearings 11 is mounted in the fastening element 9 to accommodate the intermediate pulley 6 on them. The fastening element 9 is made in the form of a sleeve in the swinging support 7 a spherical through hole 12 is made, and the variator is provided with a spherical holder 13 having a radial cut 14 over the entire width of the holder 13, installed by the inner surface on the fastening element 9, and the outer one in the spherical hole 12 of the support 7, The fastening element 9 is provided with two brackets 15, rigidly two adjustable stops 16 and 17, made in the form of threaded joints interacting with the second ends of the brackets 15, each and installed in the support 7, are fixed at one end on the element of stapling 9, and covers ayuschey spherical cage 13 clamped joints 18,

The variator works as follows.

When the terminal clamp 18 is loosened and the bolts 19 are screwed, the stops 16 and 17 are screwed or screwed on. The equalized screwing or screwing of the stops 16 and

17 aligns the intermediate pulley b in a plane perpendicular to the axis of the stops 16 and 17. The uneven and variable movement of the stops 16 and 17 aligns

pulley b in a plane perpendicular to the one indicated above. The fixation of the achieved level is leveled, achieved by clamping the terminal device 18 and tightening the bolts 19.

Claims (2)
