Abstract
The utility model discloses a large-scale shaft neck repairing and drawstring device, which comprises a semi-circle gear, fastening bolts, nylon supporting wheels, small driving gears, adjustable rubber rollers, a transducer, a speed-adjusting motor and a driving gear. The semi-circle gear is divided into an upper half and a lower half, wherein the upper half and the and lower half are fixedly connected with each other through the bolts, and the two heads of the upper half and the lower half are welded with each other through an iron board; an U-shaped groove of the semi-circle gear is respectively provided with the two nylon supporting wheels, wherein the coaxial inner sides of the nylon supporting wheels are provided with the small driving gears, the small driving gears are engaged with the rubber rollers, the driving gear drives the adjustable rubber rollers, and the two adjustable rubber rollers at the upper half and the lower half of the semi-circle gear are sheathed with rotatable sand cloth belts; and the speed-adjusting motor is connected with the transducer, and the driving gear is driven by the speed-adjusting motor. The large-scale shaft neck repairing and drawstring device is used for repairing the abrasion of the shaft neck of a rotor of a motor, has fast repairing speed, high precision and good effect, saves the time for repairing an electric power plant, shortens the repairing work period, greatly reduces the labor intensity of repairing staff, fast repairs the shaft neck, and improves the repairing effect.
Description
Technical field
The utility model belongs to process equipment after the mechanical axle journal reparation.
Background technology
The manual grinding mode is generally adopted in existing axle journal reparation, wastes time and energy, and production efficiency is low, and effect is undesirable.
Summary of the invention
At the deficiencies in the prior art part, the purpose of this utility model aims to provide a kind of large-scale axle journal and repairs the drawstring device.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of large-scale axle journal is repaired the drawstring device, comprises semi-circle gear, fastening bolt, nylon support wheel, small transmission gear, adjustable rubber rollers, rubber rollers driven wheel, frequency converter, buncher and driven wheel.Semi-circle gear divides two halves up and down, is connected and fixed with bolt, and weld with iron plate at two; At the U of semi-circle gear type groove two nylon support wheels are housed respectively, there is small transmission gear the coaxial inboard of nylon support wheel, small transmission gear meshes the rubber rollers travelling gear again and drives adjustable rubber rollers, is with the rotation abrasive belt on the two adjustable rubber rollers of two halves about the semi-circle gear; Buncher connects frequency converter, drives travelling gear by buncher.
The beneficial effect of advantage of the present utility model and generation is:
1, rotary tooling divides two halves up and down, installs and convenient disassembly.
2, drive travelling gear by buncher, travelling gear and semi-circle gear engagement, small transmission gear meshes the rubber rollers travelling gear again and drives adjustable rubber rollers, and the rotation abrasive belt that is enclosed within on the adjustable rubber rollers can be strained or loosen.The utility model has obtained application in the generator rotor shaft neck wearing and tearing recovery project of power plant, its speed is fast, and the precision height is effective, has shortened maintenance duration, for the time has been saved in the maintenance of power plant.
3, the utility model has alleviated maintainer's labour intensity greatly, and instead of manual is polished, and reaches the purpose of quick reparation axle journal, raising axle journal remediation efficiency.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 be Fig. 1 A-A ' to sectional schematic diagram.
The specific embodiment
Shown in Fig. 1-2, the little 25.00mm field repair of a kind of axle journal diameter drawstring device comprises semi-circle gear 1, fastening bolt 2, nylon support wheel 3, small transmission gear 4, adjustable rubber rollers 5, rubber rollers driven wheel 6, frequency converter 7, buncher 8 and driven wheel 9.Semi-circle gear is two halves about in the of 1 minute, and its two with length 200.00mm, the welding of thickness 20.00mm iron plate, is connected and fixed with bolt 2 respectively.Two semi-circle gears 1 cooperate with driven wheel 9 to realize rotation up and down.U type groove apart from two 180.00mm on the semi-circle gear 1 is equipped with nylon support wheel 3, there is the small transmission gear 4 of diameter 80.00mm nylon support wheel 3 coaxial inboards, drive the same U of using type slot pitch from adjustable rubber rollers 5, be with rotation abrasive belt 10 on the adjustable rubber rollers 5, buncher 8 connects frequency converter 7, drives travelling gear 9 by buncher 8.Regulate nylon support wheel 3 two semi-circle gears 1 rotates around axle journal, rubber rollers driven wheel 6 and small transmission gear 4 engagements, small transmission gear 4 drives adjustable rubber rollers 5, and the rotation abrasive belt 10 on the adjustable rubber rollers 5 is strained.Regulate the degree of tightness of abrasive belt 10 and the contact area of abrasive belt and axle journal by U type groove, the pressure of regulating 3 pairs of axle journals of nylon support wheel by U type groove is to obtain sufficient abrasive belt driving force.But the rotation and the grinding speed of frequency converter 7 and buncher 8 control gear drawstring systems are realized the accurate reparation fast of axle journal.
