Abstract
The utility model provides a collector ring for measuring transmission shaft torque, which comprises a shaft sleeve, a shell, a plurality of conducting rings and an electric brush, wherein the conducting rings are arranged on the excircle of the shaft sleeve along the axial interval, the conducting rings are mutually insulated, and wires are respectively led out from the conducting rings to connect transmission shaft torque signals required to be measured; the electric brushes are arranged in the shell and correspond to the conducting rings, the electric brush contacts are in contact with the surfaces of the conducting rings, and conducting wires are led out of each electric brush; the housing is supported on the shaft sleeve by bearings fixed to both ends of the shaft sleeve. The collector ring is simple in structure and particularly suitable for torque measurement of the transmission shaft, when the collector ring is used, the shaft sleeve replaces a protective sleeve of the transmission shaft to be fixedly connected with the transmission shaft, the conducting wire led out from the conducting ring is correspondingly connected with the torque signal line on the transmission shaft, and the conducting wire led out from the electric brush outputs a signal to an external instrument, so that torque signal output of the transmission shaft is realized, and the purpose of torque measurement is achieved.
Description
Technical field
The utility model relates to the torque measurement of turning axle, especially torque transmission shaft measurement collector ring.
Background technology
The true non-electrical quantity measurement technology of testing in the stress analysis of torque measurement, collector ring application aims are that the rotating signal on the axle (resistance strain gage signal) is converted to irrotational signal, for instrumental analysis, record.
Collector ring utilization in the rotating signal transmission is extensive, but shaft end type structure more commonly, it is the end that collector ring is installed in measured axis, collector ring rotation mandrel links to each other with the measured axis axle head, collector ring rotation mandrel size is unrestricted, machinable very little, the working speed of shaft end type collector ring can be up to commentaries on classics up to ten thousand.Though it is very extensive that the shaft end type collector ring uses, vehicle drive shaft torque is measured and can not be used the shaft end type collector ring, and sealing connects because truck drive shaft is front and back, must adopt the penetration type structure, and promptly collector ring is enclosed within the form on the transmission shaft.
Summary of the invention
Can't to use the shaft end type collector ring to carry out the problem that vehicle drive shaft torque is measured in order solving, to the utility model proposes torque transmission shaft measurement collector ring.
For this reason, the technical solution of the utility model is as follows: torque transmission shaft is measured and is used collector ring, is made up of axle sleeve, shell, a plurality of conducting ring, brush, and a plurality of conducting rings are disposed on the cylindrical of axle sleeve vertically, mutually insulated between the conducting ring is drawn lead respectively on the conducting ring; The brush setting in the enclosure, and is corresponding with conducting ring, and the brush contact contacts with the conducting ring surface, and each brush is drawn lead respectively; Shell is bearing on the axle sleeve by the bearing that is fixed on the axle sleeve two ends.
Technique scheme further is optimized for: shell is a semicircle opposite opened structure, is connected and composed the full circle shape structure that can throw off by two semi circular shells.
Of the present utility model simple in structure, be particularly suitable in the torque transmission shaft measurement.During use, the protecting pipe that axle sleeve replaces transmission shaft is fixedlyed connected with transmission shaft, draws lead and the corresponding connection of torque signal line on the transmission shaft on the conducting ring, and the lead output signal of drawing on the brush arrives external instrument, thereby realize the output of torque transmission shaft signal, reach the purpose of torque measurement.The shell that employing can be thrown off is conveniently pulled down when not measuring, and avoids wearing and tearing unnecessary between brush and the conducting ring, and maintenance and repair are convenient.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the side view of Fig. 1.
Fig. 3 is the constitutional diagram of the utility model after shell is thrown off.
Embodiment
As shown in Figure 1, 2, 3, shell 3 is bearing on the axle sleeve 1 by the bearing 14 that is fixed on the axle sleeve two ends; Shell 3 is semicircle opposite opened structures, constitute by semi circular shells 16, semi circular shells 19, semi circular shells 16, semi circular shells 19 1 ends connect by hinge 15, and semi circular shells 16, semi circular shells 19 other ends are provided with fixed support 17, and semi circular shells 16, semi circular shells 19 connect by fixed support 17, bolt 18.Shell 3 is provided with fixedly suspension ring 6, is fixed on the vehicle frame to make things convenient for shell 3.
Be arranged in juxtaposition a plurality of dead rings 7 on axle sleeve 1 cylindrical mutually, on axle sleeve 1 cylindrical, constitute insulation course, a plurality of conducting rings 5 vertically fixed interval on the dead ring on the sleeve outer circle 7, thereby guarantee mutually insulated between the conducting ring 5, draw lead on the conducting ring 5 respectively and be aggregated on the lead frame 2 in the axle sleeve outside.Brush 4 is provided with in the enclosure, and is corresponding one by one with conducting ring 5, and the brush quantity corresponding with each conducting ring 5 is 2,2 brush positioned opposite; Each brush 4 is made up of brush cover 10, brush contact 11, compression spring 9, guide pole 8, brush contact 11 slides in brush cover 10, compression spring 9 is installed on the guide pole 8, compressing guide pole 8 closely contacts with brush contact 11 all the time, and guide pole 8 other ends are drawn lead and are connected on the connector socket 13 on the shell 3.
Semi circular shells 16, semi circular shells 19 also can be connected to the full circle shape structure that can throw off by other known configurations, are not limited to the structure of describing in the above-described embodiment.
Shell 3 also can be an one-piece construction, and can realize torque measurement this moment fully, but have the shortcoming that causes wearing and tearing in brush contact and the conducting ring long-term work.
Brush quantity, the position on shell corresponding with each conducting ring also are not limited to the structure in the above-mentioned embodiment, and brush can be 3 or more, and the position of brush on shell can be uniform or non-uniform.
Because structure conversion and combination that above-mentioned technical characterictic produces are conspicuous, are appreciated that thus the numerous embodiments of generation all should fall into protection domain of the present utility model.
