Abstract

FIELD OF THE INVENTION The invention relates to agricultural machinery. The purpose of the invention is to increase operational reliability by improving tightness. The reel of the agricultural machine contains the central pipe 1. Inside the hermetic compartment of the pipe 1 there is a hydraulic motor and a planetary gear. The connection of the gear 9 of this gear with the pipe 1 is made in the form of a series of bolted pairs having a bolt 14, the nut 15 is screwed onto the threaded part of the nut 15. The nut 15 is inserted into the slot of the ring gear 9 with a cylindrical part with a side clearance. On the other hand, the nut 15 is provided with a bolt 18. Improving the tightness of the compartment at the joints of the pipe 1 with the gear 9 is provided by compensating for the distortions of the bolt pair, which is achieved by the angular and linear displacement of the nut 15. 1 ° c. f-ly, 3 ill.

Description

The invention relates to agricultural machinery, mainly to roller coaters and headers of combine harvesters, and is an improvement of the invention in accordance with the author. St. No. 1304778.

The purpose of the invention is to increase operational reliability by improving tightness.

FIG. 1 depicts the proposed reel, general view; in fig. 2 shows section A-A in FIG. one; in fig. 3 shows the node I in FIG. one.

The proposed reel contains a central tube 1 with beams 2 fixed on it. Inside the hermetic compartment of the central tube 1 formed by the outer 3 and inner 4 plugs, there is a hydraulic motor 5 with an end flange 6 having channels for supplying the working

fluids to the hydraulic motor 5, and a planetary gear transmission consisting of a sun shaft gear 7, satellites 8, a ring gear 9 and a housing 10 drove. located on the support 12. The sealed compartment is filled with a heat-transfer fluid 13 to the working level. The crown gear 9 is connected to the wall of the central tube 1, a row of bolted pairs arranged around its circumference, each having a bolt 14, the threaded part of which is screwed into the nut 15, and the head having a cylindrical headrest is located outside. To ensure tightness at the locations of bolted pairs on the surface of the central pipe 1

annular grooves in which the connections of the central pipe 1 and the corona-enclosed sealing elastic ring gear 9 are provided to the compensator 17. Each of the nuts 15 is inserted by the distortions of the bolted pair. Compensation

the cylindrical smooth part of the groove is co-achieved by the angular displacement of the nut 15, an even gear 9 with a side clearance, 5 since it is installed in the groove which exceeds the largest of the fields of the peripheral gear 9 freely and the misalignment

to the location of the holes under the bolts of the central pipe 1 — the linear displacement 14 on the surface of the central pipe 1; with the cue nut 15, within the size of the shoulder, it rests against the body with a crown Y-gap between the cylindrical part

gears 9. In order to prevent the nut 15 and the groove in the ring cogwheel of the nut 15 from escaping from the groove during assembly, a bolt 18 is used, which is screwed into the nut 15 on the reverse side and rests on the hub of the ring gear 9.

the turn 9. The nut 15 in any position is in contact with the edges of the shoulders with the inner surface of the gear 9, thus achieving a rigid connection of the gear 9 and

The reel works as follows.

The sun shaft gear 7, rotating with the shaft of the hydraulic motor 5, rotates the satellites 8, which transfer the torque to the crown neck 20 according to the ed. St. No. 1304778, characterized by the turn 9. Together with it comes in the direction that, in order to increase the operation, the central pipe 1. The torque from the gear 9 to the central pipe 1.

Claims (2)

Claim 1. The reel of the agricultural machine pipe 1 is transmitted using bolts 14, which pull the ring gear 9 and the wall of the pipe 1. When the latter rotates, the housing drove 10, the hydraulic motor 5 and the end flange 6 remain stationary, since the axial portion of the end flange 6 is rigid fixed in support 11 on support 12, and coolant 13 constantly mixes, lubricates the gears of the planetary gear and at the same time cools the hydraulic motor 5, while intensively releasing heat to the walls of the central tube 1 and the beams 2. 25 reliability by improving tightness, the connection of the ring gear of the planetary gear with the central tube is made in a series of bolt pairs, each nut of which is placed on one side in the slot made in the ring gear and on the other side is fitted with an adjustable ring gear hub on the other. 3Q 2. Reel according to claim 1, characterized in that the nut in the groove of the ring gear is arranged radially with a lateral clearance exceeding the largest of the tolerances on the size of the holes in the wall of the central tube. nuts 15 and the groove wall in the crown gear; the turn 9. The nut 15 in any position is in contact with the edges of the shoulders with the inner surface of the gear 9, thus achieving a rigid connection of the gear 9 and by auth. St. No. 1304778, characterized in that, in order to increase the exploitation of the pipe 1. Claims 1. Agricultural machine reel reliability by improving tightness, the connection of the ring gear of the planetary gear with the central tube is made in a series of bolt pairs, each nut of which is placed on one side in the slot made in the ring gear and on the other side is fitted with an adjustable ring gear hub on the other. Q 2. Reel according to claim 1, characterized in that the nut in the slot of the ring gear is arranged radially with a lateral clearance exceeding the largest of the tolerances on the dimensions of the arrangement of the holes in the wall of the central tube. 1 IS x YD 18 FIG.
