Description
Technical field
A kind of rail prosthetic device is the utility model is related to, more particularly to a kind of polishing motor is connected with internal thread emery wheel
Device.
Background technology
In the 1950s, with the fast development of various countries' economy, railway transportation freight volume and the speed of service are comparatively fast sent out
Exhibition.Therewith, the abrasion of rail waveform, contact fatigue equivalent damage are increasingly severe, influence the security and economy of railway transportation.
The maintenance and maintenance of rail just seem more and more important, rail grinding machine occur, polishing reparation is carried out to rail.
In the prior art, repair rail profile by grinder buffing to wear away, emery wheel type of drive is divided into two kinds of hydraulic motors
Driven with motor, emery wheel rotation carries out preventative and prosthetic to the rail on circuit and is ground, to the abrasion of rail undaform, rail
The diseases such as fat edges, saddle-shape abrasion, welding depression and fish scale crackle eliminate, and extend rail service life, improve wheel rail relation, drop
Low noise, improve security and reduce maintenance cost.
Hydraulic motor of the prior art at least has the following disadvantages with internal thread emery wheel attachment device：
Band internal thread emery wheel connection structure is complicated, of high cost, hydraulic system easily leaks.
The content of the invention
The purpose of this utility model is to provide a kind of polishing motor and with internal thread emery wheel attachment device.
The purpose of this utility model is achieved through the following technical solutions：
The polishing motor of the utility model is with internal thread emery wheel attachment device, connection is fixed with the axis for motor of polishing
Set, the connector sleeve is connected with connecting flange, and the lower end of the connecting flange is equipped with external screw thread, the external screw thread and with internal thread
Emery wheel connects.
The polishing motor that the utility model embodiment provides it can be seen from above-mentioned technical solution provided by the utility model
With band internal thread emery wheel attachment device, various rail grinding machines are applicable in, for repairing the wavy abrasion of rail, finishing Wheel Rail Contact
Face etc. is various due to the steel rail defect that vehicle travels on rail and produces, into the preventative maintenance of row line rail.Structure letter
It is single, cost-effective, maintenance cost is low, easy to maintain.

Embodiment
With reference to the attached drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out clear
Chu, be fully described by, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole realities
Apply example.Embodiment based on the utility model, those of ordinary skill in the art are obtained without making creative work
The every other embodiment obtained, belongs to the scope of protection of the utility model.
The polishing motor of the utility model with being with internal thread emery wheel attachment device, its preferable embodiment：
Connector sleeve is fixed with the axis of polishing motor, the connector sleeve is connected with connecting flange, under the connecting flange
End is equipped with external screw thread, and the external screw thread is connected with internal thread emery wheel.
The connector sleeve is equipped with locating slot and through hole, and the connecting flange is equipped with positioning table and threaded hole, the connector sleeve
Positioning is coordinated and by the through hole and threaded hole connection bolt by the locating slot and positioning table between connecting flange
Connection.
Flat key is equipped between the axis and the connector sleeve of the polishing motor.
The shaft end of the polishing motor is equipped with threaded hole, and gland and locking pad are equipped with through hole, and gland bolt passes through the spiral shell
The gland and locking pad are pressed on the shaft end of the polishing motor by pit, while the connector sleeve is pressed on by the gland
On the axis of the polishing motor.
Specific embodiment：
As shown in Figure 1, Figure 2, Figure 3 shows, motor is polished with installing spiral shell with internal thread emery wheel attachment device, polishing motor shaft end band
Pit, polishing motor is connected by flat key with connector sleeve, and connector sleeve is fixed on motor master through gland by gland bolt
On axis, the gland bolt is fixed by locking pad, and the gland has a bolt hole, described locking to be lined with bolt hole, the connection
It is cased with locating slot, bolt hole；Connecting flange has the locating slot precise positioning of positioning table and connector sleeve, then will be even by connecting bolt
Acting flange is fixed with connector sleeve, and the connecting flange has positioning table, threaded hole, external screw thread；The external screw thread of connecting flange is used to pacify
Fill tapped emery wheel.This structure realizes that tapped emery wheel is connected reliable, simple in structure, cost-effective, dimension with motor
It is low, easy to maintain to protect cost.
The polishing motor of the utility model is with internal thread emery wheel attachment device, being applicable in various rail grinding machines and being used to repair
The wavy abrasion of rail, finishing running surface of wheeltrack etc. are various due to the steel rail defect that vehicle travels on rail and produces, and carry out
