Known rotation device of the manipulator logging machinery used on machines small-and medium-duty and has a limited angle of rotation.
Closest to the invention is a rotation device of the manipulator harvesting machine, comprising a support rotatable roller, the lower rotary part of which is rigidly fixed on the frame of the self-propelled chassis, and the upper rotary part of the pivot roller is rigidly mounted a turntable on which is mounted the arm and the rotation mechanism rotating platform with a manipulator in the horizontal plane around the vertical axis (Circles B.C., Borman M.A., Ermolov VP, Queens, V.E., Popov BV Felling-bunching machine PL-19. - M.: Genre Differences. prom the terrain, 1982. - 288 S., see p.15 5, p.20 9, 21, 10, p.33 and Fig.19).
The disadvantages of a turntable manipulator forest machines are the complexity and intensity of construction, consolidate mounting pinion and ensure alignment of the leading and driven gears.
The technical result is to reduce material consumption, simplify the design and increase the durability.
The technical result is achieved by the fact that the proposed rotation device of the manipulator harvesting machine includes a support rotatable roller, the lower rotary part of which is rigidly fixed on the frame of the self-propelled chassis, and the upper rotary part of the pivot roller is rigidly mounted a turntable on which is mounted the arm and the rotation mechanism rotating platform with a manipulator in the horizontal plane can be rotated around a vertical axis, and the new is that the mechanism of rotation of the turntable is made in the form of a vane motor, a housing which is rigidly connected to the upper rotary part of the pivot roller, and the inner part with the blade rigidly connected with dims the second part of the non-pivot roller, while the Central part of the inner part is made in the form of a hollow pipe, and the casing is provided with a hole for the supply of fluid withdrawal, and the blade inner parts are provided on both sides of valves installed on the end-to-end channels of the blade.
The proposed construction of a turntable manipulator harvesting machine reduces the complexity and intensity of construction, excludes outdoor gear.
1 shows a rotation device of the manipulator harvesting machine, the section; figure 2 is a section a-a in figure 1.
Rotation device of the manipulator harvesting machine includes a support rotatable roller containing the lower non-part 1, which is rigidly fixed through the support ring 2 on the frame 3 self-propelled chassis, the upper rotary part 4, on which is rigidly mounted a turntable 5 with a handle (not shown). The upper rotary part 4 mounted for rotation relative to the lower rotary part 1 on the rolling elements 6, for example, rollers. Support ring 2 is rigidly installed in the inner part 7 blade is of hydromotor is rigidly fixed thereto blade 8. The inner part 7 is made of a hollow tube with optional inside its Central manifold (not shown) of the hydraulic transmission, and the blade 8 are rigidly connected to the outer surface of the inner pipe portion 7. On a turning platform 5 through the flange 9 is fixed to the housing 10 of the motor, the internal cavity of which is rigidly mounted sector 11 channels 12 and 13 inside for supplying-discharging working fluid to drive the motor. The housing 10 and the inner part 7 is fitted with removable from their mounting and dismantling. Between the inner part 7 and the housing 10 are mounted seal 14, for example, gaskets. Between the blade 8 and the housing 10 and between the sector 11 and the inner part 7 is also installed seal 15. In the housing 10 with holes 16 and 17 for the supply of fluid withdrawal, exactly coinciding with the channels 12 and 13. The blade 8 is provided with valves 18 and 19, mounted on both sides of the blade 8 and held in closed position by means of elastic elements 20, for example, the tension springs. The valves 18 and 19 are installed on the end-to-end channels 21 and 22, made in the blades 8.
The operator, by controlling the valve (not shown), directs the flow of the working fluid in the hole 1 or 17, under the pressure of the working fluid of the body 10 is rotated relative to the inner part 7, starting from the blade 8 and the housing 10 rotates a turntable 5. If the working fluid is fed under pressure into the hole 16 and the valve 12, through the channel 13 and the hole 17, the working fluid is discharged into the tank (not shown), while a turntable 5 is rotated counterclockwise. If the working fluid is fed under pressure into the hole 17 and the channel 13, then through the channel 12 and the opening 16 is poured into the tank and a turntable 5 is rotated clockwise. With a sharp rise in pressure of the working fluid between the blade 8 and the sector 11 or hydrodynamic shock triggered the valves 18 or 19, preventing the dynamic loads and the failure of the hydraulic units and process equipment logging machine.
The proposed rotation device of the manipulator harvesting machine reduces the complexity and intensity of construction, eliminates the use of open gears, increases the efficiency of its use.

Rotor (internal part) with plates is rigidly connected to lower non-rotary part of roller rotary support. Body is equipped with openings for supply and drain of working fluid. EFFECT: device design is simplified, its metal intensity is reduced and wear resistance is increased.
Steering gear // 2340544
FIELD: transport; mechanics.
SUBSTANCE: steering gear contains hydraulic motor at the shaft of which a carrier with single-crown star wheels engaged into mesh with two crown wheels the first being unmovable fixed in reduction gear casing, the second, running, is connected with output shaft or is made as a part of it. Running crown wheel is installed in one rolling bearing and one sleeve bearing with working movable surface of sleeve bearing being the outer surface of running crown wheel and immovable surface being inner surface of reduction gear casing. For the case of emergency switch-off of the main drive carrier has tooth rim that may be engaged into mesh with plug-pinion which in this case is installed into filler plug orifice and may be turned by wrench.
