Abstract

A fast pulley extractor is mainly composed of a cross beam, a hook head and a jackscrew. In work, the two symmetrical sides of a coupling are hooked by the hook head and inserted in the two sides of the cross beam respectively, the jackscrew is screwed into a middle screw hole of the cross beam and makes contact with a shaft head, and the coupling can be pulled out by applying forward-spinning force to the jackscrew.

Description

Quick pulley extractor
Technical field: fast pulley extractor belongs to mechanical manufacturing field, is widely used in all devices that coal mine machinery, machine-building, work post machinery etc. manufacture field, is Automobile Service, mine, railway, civil aviaton, sea-freight etc. manufacture, overhaul necessary instrument.
Background technology: by domestic and international complete search, existing pulley extractor mainly contains three and grabs leading screw pulley extractor and hydraulic wheel puller, has certain limitation mostly in use, can not ensure general and good practicality.Quick pulley extractor can address these problems.Through Access point, in the industry, also there is not innovation and creation and the product of identical type.
Summary of the invention: pulley extractor is mainly made up of three parts fast: cross-arm, gib head and jackscrew, during work, gib head hooks the symmetrical both sides of shaft coupling, and insert cross-arm both sides respectively, jackscrew is screwed into cross-arm center screw position, contact with spindle nose, impose the power of dextrorotation to jackscrew, shaft coupling can be pulled up.
Quick pulley extractor, is characterized in that: gib head, jackscrew and cross-arm are fast fixing, and when jackscrew dynamics is inadequate, interchangeable a thousand pieces of gold top replaces, the distance adjustable between two-arm and gib head, can along with the distance of shaft coupling diameter adjustment two-arm, and scope of can pulling out is wide.
Quick pulley extractor compared with prior art has the following advantages:
Structure is simple, and be easy to processing, economical and practical, applicability is strong.
Accompanying drawing illustrates:
Accompanying drawing is quick pulley extractor schematic diagram.
1, arm; 2, adjusting rod; 3, cross-arm; 4, jackscrew;
5, shaft coupling; 6, spindle nose; 7, gib head
Detailed description of the invention: now illustrate to the drawings as examples: when shaft coupling (5) need be pulled out, by two gib heads (7) respectively symmetry hook shaft coupling (5) both sides, again gib head (7) and two-arm (1) both sides are inserted respectively cross-arm (3) to parallel, again adjusting rod (2) is adjusted, jackscrew (4) contacts with spindle nose (6), start dextrorotation jackscrew (4), jackscrew (4) progressively strengthens with the positive spin of spindle nose (6), then cross-arm (3) drives gib head (7) to make shaft coupling (5) and spindle nose (6) start displacement, until pull up shaft coupling (5).
