Abstract
The utility model discloses a wheel set and hollow shaft driving device for traction motor tests. The driving device comprises a traction motor, a pinion, a large gear and a wheel set, wherein the pinion is driven by a rotating shaft of the traction motor and meshed with the large gear, and two rolling wheels of the wheel set are connected through a rolling wheel shaft. The driving device is characterized by further comprising a hollow shaft, wherein a hollow shaft sleeve is arranged on a body of the traction motor; a rolling bearing is mounted on the hollow shaft sleeve in a sleeving manner; the large gear is mounted on the rolling bearing in a sleeved manner; the hollow shaft penetrates through the hollow shaft sleeve; connecting discs are arranged at two ends of the hollow shaft respectively, one connecting disc, which is close to the large gear, is connected with the large gear through a first elastic connecting rod, and the other connecting disc is connected with one closer rolling wheel through a second elastic connecting rod. According to the driving device, a two-stage elastic separation device is arranged, so that the wheel set and the traction motor are in elastic transmission, so that the driving device has better dynamical properties, and the working stability is better than that of hard connection transmission.
Description
Technical field
The utility model relates to a kind of wheel for traction electric machine experiment to hollow shaft driving device, relates in particular to a kind of wheel with two-stage elastomeric isolation for traction electric machine experiment to hollow shaft driving device.
Background technology
Trunk railway electric locomotive, industrial and mineral electric locomotive, diesel-electric locomotive and various elec. vehicle (as battery-powered vehicle, city electric car and subway elec. vehicle) are upper is traction electric machine for the motor drawing, in the time that it uses, all need traction electric machine and actuating device thereof to carry out strict experimental study.Traditional for traction electric machine experiment actuating device due to wheel to and traction electric machine between for to be firmly connected, its dynamic performance is poor, working stability is good not.
Summary of the invention
The purpose of this utility model is just to provide in order to address the above problem a kind of wheel for traction electric machine experiment with two-stage elastomeric isolation to hollow shaft driving device.
The utility model is achieved through the following technical solutions above-mentioned purpose:
A kind of wheel for traction electric machine experiment is to hollow shaft driving device, comprise traction electric machine, miniature gears, big gear wheel and wheel are right, described miniature gears is driven by the rotating shaft of described traction electric machine, described miniature gears engages with described big gear wheel, described wheel between two right rollers connects by roller shaft, described wheel also comprises hollow shaft to hollow shaft driving device, on the body of described traction electric machine, be provided with hollow shaft sleeve, on described hollow shaft sleeve, be set with antifriction-bearing box, described big gear wheel is sleeved on described antifriction-bearing box, described hollow shaft is through described hollow shaft sleeve, the two ends of described hollow shaft are respectively arranged with terminal pad, described terminal pad near described big gear wheel is connected with described big gear wheel by the first elastic link, described in another, terminal pad is connected with roller described in close one of them by the second elastic link.
In said structure, the first elastic link and the second elastic link form two-stage elastic connection structure, form two-stage elastomeric isolation.
Particularly, described the first elastic link and described the second elastic link are the six roots of sensation of evenly installing on the circumference of the described terminal pad of correspondence.
