Abstract

FIELD OF THE INVENTION The invention relates to agricultural machinery. The purpose of the invention is to increase the reliability of fixation of the bearing and reduce the complexity of installation and disassembly. The fastening device for pipes 1 rakes on the crosspiece of an eccentric reel contains a split bearing in the form of a half-bearing 2 formed at the outer end of beam 3 and held in this place by a separate liner 5 bracket. On the liner 5 side, the bracket is provided with projections 9 having a width smaller than the bracket. The staple is elastic and holds the liner 5 by means of the projections 9. The tight fixation of the liner 5 prevents the uneven wear of its friction surfaces. Pre-installation of the liner 5 in the bracket with fixation in it allows you to install the formed blocks at any position of the reel tubes. 4 il.

FIG. one

FIELD OF THE INVENTION The invention relates to agricultural machinery, in particular to reels of combine harvesters.

The purpose of the invention is to increase the reliability of fixation of the bearing and reduce the complexity of installation and disassembly.

FIG. 1 shows the proposed device; cross section; in fig. 2 - the same, longitudinal section; in fig. 3 - liner installed in the bracket; in fig. 4 is a section A-A in FIG. 3

The fastening device for pipes 1 of the rake of an eccentric reel contains a split bearing. in the form of a half-bearing 2 formed on the outer end of the beam 3 of the cross and the beam 3 held in this place by the clip 4 of the individual insert 5. On the outside 6 on the insert 5 there is a tenon 7 inserted into the hole 8 of the bracket 4. On the side of the insert 5 the clip 4 is fitted the protrusions 9 having them, the width of the smaller width / of the bracket 4 (), and holding them for the edges 11 located near the plane 10 of the bearing connector of the bearing 11. The bracket 4 is made prestressed and elastically holding the insert 5 for its outer edges by means of the projections 9: Bracket 4 with installed in s liner 5 is fixed by bolt connection 12 in the line 3.

The device works as follows.

The fastening of the pipes 1 Rablin is carried out in the following manner.

Before assembling the reel, overcoming the elasticity of the bracket 4, a contribution of 5 with a small

force put inside it, having a spike 7 in the hole 8. The liner 5, sewn up in the bracket 4, is held by the protrusions 9 by the edges 11. After installing the bracket 4 together with the liner 5 in place and securing it by bolting 12 with the beam 3, the liner 5 is firmly and firmly fixed. Dense fixing of the liner 5 prevents uneven wear of its friction surfaces and increases the reliability of the device.

The execution of the protrusions 9 already of the staples 4 retains the smoothness of the bending of the lateral edges of the staples 4, which prevents the entrapment of the plant mass.

Installing the insert 5 in the bracket 4 previously with fixation in it allows you to install and remove the formed blocks at any position of the pipes 1 rake of reel.
