Abstract
The utility model provides an intelligent sensor for urban mass transit bearings, which comprises a coder, a dust cap, a seal cover and a sensing unit, wherein the coder is sealed in the inner ring of a subway bearing through the dust cap; the dust cap is fixed on the subway bearing through the seal cover; the sensing unit is in electrical signal connection with the coder and external receiving equipment respectively. The intelligent sensor has the advantages that the method for monitoring the running state of the subway bearing accurately in a real-time manner can be improved; the problems such as over-large friction and over-fast temperature rise in the bearing, which can affect the normal work of the bearing and thus bring bad consequences to the safe on-time operation of a train, are avoided; the subway bearing can be maintained conveniently; the phenomena of untimely monitoring caused when a complex monitoring device is mounted outside the subway bearing in the prior art can be reduced.
Description
(1) technical field
The utility model relates to construction design of journal bearings field, is specifically related to a kind of urban track traffic bearing intelligent sensor.
(2) background technology
Urban track traffic enters unprecedented Rapid development stage, and according to incompletely statistics, at present domestic 32 cities are exceeding 70 building subway line, gross investment more than 8,000 hundred million, and the total project investment volume getting the Green Light has more reached more than 1.5 trillion.Successively put into effect a series of policies since country in 1999, encouraged sophistication equipment, promoted energetically production domesticization work.Requiring 70% of subway system electromechanical appliance total purchase used valency must be that domestic local enterprise manufactures.Wherein track traffic bearing industry is indispensable important component part.Bearing can be stablized, operation efficiently, is that vehicle guarantees safe key factor in operational process, so monitoring bearing operating condition is a requisite important indicator in vehicle monitoring system.Mostly the existing operating locomotive of China, be external sensor monitoring, and not only complex structure, is difficult to maintenance, and takies the space that bear box is very large.
(3) summary of the invention
The purpose of this utility model is to provide a kind of can improvement in the time of operation accurately the running state of subway bearing to be carried out to the mode of monitoring in real time, avoid bearing because of the appearance that internal friction is excessive, the problems such as height are crossed in temperature rise, and the normal work of bearing is exerted an influence, and then safe, the operation on schedule of train are produced to adverse consequences, be convenient to maintenance, the maintenance of subway bearing simultaneously, reduce because originally complicated control monitor unit is installed is caused the monitoring urban track traffic bearing intelligent sensor that not in time etc. situation occurs subway bearing is outside.
The purpose of this utility model is achieved in that it comprises coder 1, cover of dust 2, seal closure 3 and sensing unit, coder 1 is sealed in subway bearing inner ring by cover of dust 2, cover of dust 2 is fixed on subway bearing by seal closure 3, and sensing unit respectively electric signal connects coder 1 and outside reception facilities.
The utility model also has some technical characterictics like this:
1, described seal closure 3 is fixed on subway bearing by clamp nut 4;
2, described coder 1 is interspersed on the support wheel of making of ABS mixing nylon by N, S utmost point magnetic stripe, bonding by silica gel between magnetic stripe;
3, described N, S utmost point magnetic stripe comprise 80 couples of N, S utmost point magnetic stripe.
Accurately the running state of subway bearing is carried out to the mode of monitoring in real time in order to improve in the time moving, avoid bearing because of internal friction excessive, the appearance of the problems such as height is crossed in temperature rise, and the normal work of bearing is exerted an influence, and then safety to train, operation on schedule produces adverse consequences, be convenient to the maintenance of subway bearing simultaneously, maintenance, reduce because originally complicated control monitor unit is installed is caused the monitoring generation of situation such as not in time subway bearing is outside, the inner structure of the subway bearing that the utility model is used urban track traffic in conjunction with actual working conditions has been carried out research and development design, make monitoring sensor, coder and bearing height are integrated, the share of market of Liao Wo company product is expanded in the research and development of this product simultaneously, for enterprise brings huge profit, promote the localization process of the subway bearing that urban track traffic uses.
The beneficial effects of the utility model have:
(1) by encoder applies in bearing, the rotating speed of bearing is monitored.Coder is interspersed on the support wheel of making of ABS mixing nylon by 80 couples of N, S utmost point magnetic stripe, and bonding by silica gel between magnetic stripe, functional component is permanent-magnet ferrite, and magnetic-field intensity exceedes 500 Gausses, and coercive force exceedes 60KA/m.
(2) adopt cover of dust sealing, by seal closure fixedly make coder and bearing height integrated.Can prevent the interference of emergency situation prompting in time and destructive material.
In conjunction with Fig. 1, in the product structure of coder, magnet-wheel magnetic in coder can be preserved for a long time, wherein because of the magnetic pole difference (N, S) of permanent magnet, the variation that rotation causes magnetic pole to replace, by the identification of sensing unit, collection information feedback, thus, the monitoring device of railcar can be monitored the operating condition of bearing accurately.Principle of work is: in the time of bearing normal operation, coder will be followed bearing inner ring and will be rotated, owing to being distributed in the magnetic pole difference of the permanent magnet on coder, the frequency that sensing unit can replace by recognition coding device N, the S utmost point, and rotating speed and running condition to bearing is monitored accurately.The utility model is integrated by the height of coder and bearing, can guarantee identical with bearing inner ring rotating speed, reduce occur monitoring error probability.Not only can monitor in real time train operation speed exactly, guarantee safe, the operation on schedule of subway, and can replace the monitoring device of original complexity, Free up Memory, thus alleviate the burden of wheel.
The technological process of the utility model coder is as follows: (1) magnetic rubber material: to ABS particle grind → with magnetic carry out mixing → check composition; (2) mould: Design of Dies → mould manufacture → mould check; (3) steel frame: steel frame processing → steel frame check; (4) coder: magnetic rubber and steel frame are carried out to sulphurization → arrange → check → magnetize → magnetic detection → finished product in mould.
(4) accompanying drawing explanation
Fig. 1 is the utility model scheme of installation;
Fig. 2 is the utility model structural representation;
Fig. 3 is coder magnetic pole distribution schematic diagram.
(5) specific embodiment
The utility model below in conjunction with the drawings and specific embodiments is further described:
In conjunction with Fig. 2, the present embodiment comprises coder 1, cover of dust 2, seal closure 3 and sensing unit, clamp nut 4, coder 1 is sealed in subway bearing inner ring by cover of dust 2, cover of dust 2 is fixed on subway bearing by seal closure 3, seal closure 3 is fixed on subway bearing by clamp nut 4, and sensing unit respectively electric signal connects coder 1 and outside reception facilities.Coder is interspersed on the support wheel of making of ABS mixing nylon by 80 couples of N, S utmost point magnetic stripe, and bonding by silica gel between magnetic stripe, functional component is permanent-magnet ferrite, and magnetic-field intensity exceedes 500 Gausses, and coercive force exceedes 60KA/m.
