RU2729892C2 - Reamer for restoration of half-axle seat mounting and restoration of tractor half-axle t-130, t-170 - Google Patents

Abstract

FIELD: transport machine building.

SUBSTANCE: invention relates to road construction equipment for repair of semi-axle seat in frame of caterpillar tractor T-130, T-170. Reamer is used for restoration of semi-axle seat in frame with accurate fixation with possibility of clearly centering reamer in place of ellipse. Invention can replace only conical cutting part of working surface, which recruits ellipse, depending on ellipse development.

EFFECT: simplified repair of tractor half-axle seat.

Description

The invention relates to the field of road construction equipment for the repair of the undercarriage of the tracked tractor T-130, T-170.

This invention allows the reamer to restore the semi-axle seats in the tractor frame during partial disassembly, while the reamer is installed in the standard place of the semi-axle attachment, which makes it possible to obtain a strictly centered cone, only enlarged from the standard one and by manually rotating the reamer the sampling at the semi-axle landing in the tractor frame is eliminated , with the possibility of replacing the conical part of the nozzle, which samples the ellipse, depending on the development of the ellipse, with the installation of the restored semiaxis on the restored landing site.

EFFECT: invention makes it possible to bring the running gear of the tractor into a technically sound condition with minimal expenditures of money, costs in time and idle time of the tractor for repair.

Designed for restoration in various operating conditions: in the field, in the garage conditions of the repair base without complete disassembly of the tractor.

Attached is a drawing of the invention and a technological map of the successive repair of the tractor. Brief description of the drawing:

- In FIG. 1 shows an old worn out semi-axle with changed dimensions:

- 1 - ∅ 70 mm

- 2 - ∅ 80 mm

- 3 - ∅ 85 * 2 mm

- 4 - 400 mm

- 5 - 190 mm

- 6 - 250 mm

- 7 - ∅ 32 mm - through technological hole

- 8 - ∅ 16 mm - through technological hole

- 9 - ∅ 32 mm - through technological hole

- 10 - ∅ 16 mm - through technological hole

- In FIG. 2 shows a tapered reamer:

-1 - ∅ 144 mm

- 2 - ∅ 130 mm

- 3 - ∅ 70 mm

- 4 - 180 mm

- 5 - 110 mm

- 6 - 17 mm

- In FIG. 3 shows a finger that fixes the reamer from turning:

- 1 - ∅ 17 mm

- 2 - 110 mm

- In FIG. 4 shows a fluoroplastic ring, which is designed to slide when the tightened reamer is turned in the semiaxis seat:

- 1 - ∅ 85 mm

- 2 - ∅ 121 mm

- In FIG. 5 shows the nut, which tightens the reamer to obtain a clear fixation and centering:

- 1 - ∅ 85 * 2 mm

- 2 - ∅ 121 mm

- 3 - ∅ 14 mm

- 4 - 30 mm

- 5 - ∅ 16 mm

The manufacture of the reamer consists of: an old unnecessary semi-axis and a nozzle "steel grade 40XH" for removing the ellipse (Fig. 2). The ellipse reamer nozzle can be produced in different diameters depending on the ellipse production. Also attached is a drawing of the sequential assembly of the reamer for work (Fig. 6).

Claims (1)

A reamer is a conical tool for restoring the permeability of deformed casing pipes, for milling the inner surface of pipes, characterized in that this reamer is designed to restore the semiaxis seat in the frame with a clear fixation with the ability to clearly center the reamer in the place where the ellipse is generated, while it is possible to replace only the conical cutting part of the working surface, which cuts the ellipse depending on the ellipse production.
