Abstract
The utility model relates to a magnetic-sensitive contactless potentiometer, which is characterized in that the magnetic-sensitive contactless potentiometer is composed of a magnetic iron, a magnetic iron seat, a bearing seat, a chip, and a chip protective layer, wherein, the magnetic iron is fixed on the magnetic iron seat through screw bolts, and the magnetic iron seat is fixed on the bearing seat through the screw bolts; two bearings which are divided by a cushion ring are installed on the bearing seat, and a rotation shaft is fixed on the two bearings; a support frame is fixed on the bearing seat through two screw bolts, the middle part of the support frame is provided with a poly magnet, and the lower end surface of the poly magnet is fixedly provided with the chip which is provided with the chip protective layer; a casing is fixed through a tight fit between the casing and the bearing seat, and the top end of the casing is provided with two holes. The utility model improves the sensitivity and the linearity of products.
Description
The utility model relates to potentiometer, particularly a kind of Magnetic Sensing Contactless Potentiometer.
Magnetic Sensing Contactless Potentiometer is to be media with magnetic field, various non electrical quantities (as displacement, rotating speed etc.) is converted to the variation of resistance value, thereby non electrical quantity is measured and controlled.Be widely used in inclinometer, equilibristat, gradiometer and pressure tool etc. now.But there is following defective in existing product: at first magnet is to be secured on the magnetic receiver by glue, because the magnetic field of magnet fixes, magnet is fixed on the sensitivity and the linearity that is unfavorable for improving product behind the magnetic receiver with glue; Secondly, bearing is the separately assembling of both sides from bearing pedestal, is partly separated by the bearing pedestal intermediate projections between the two bearings, and this mounting means influences the axiality of rotating shaft, and then influences the linearity of product; At last, chip protection layer is coated in epoxy resin and protects chip on the chip, and its surface irregularity is not easy to observe.
The purpose of this utility model is to provide a kind of Magnetic Sensing Contactless Potentiometer of highly sensitive, stable performance.
The purpose of this utility model is achieved in that a kind of Magnetic Sensing Contactless Potentiometer, it is characterized in that: be to be made of magnet, magnetic receiver, bearing pedestal, chip and protective layer thereof; Wherein magnet is to be fixed on the magnetic receiver by bolt, magnetic receiver is fixed on bearing pedestal by bolt again, Bearing Installation is being separated by packing ring on the bearing pedestal and between the two bearings, rotating shaft is fixed on two bearings, support is fixed on the bearing pedestal by two bolts, centre at support is equipped with gathering magnet, and the lower surface of gathering magnet is fixed with the chip that has chip protection layer; Shell is to be fixed by closely cooperating between shell and the bearing pedestal, and the top of shell has two holes.The utlity model has following advantage owing to there is above-mentioned structure to make: at first, magnet is to be fixed on the magnetic receiver by bolt, thereby the sensitivity and the linearity of product are improved in the position that so just can adjust magnet on request; Secondly, two bearings of the present utility model be pack into from the same end of bearing pedestal they between separated by packing ring, thereby improved the axiality of rotating shaft, improved the linearity of product.
Below in conjunction with drawings and Examples the utility model is further described.
Fig. 1 is a whole profile of the present utility model;
Fig. 2 is the structure chart of magnet of the present utility model;
Fig. 3 is the profile of magnetic receiver of the present utility model;
Fig. 4 is bearing block structure figure of the present utility model.
Among the figure, 1-magnet, 2-shell, 3-magnetic receiver, 4-bearing pedestal; The 5-gathering magnet, 6-rotating shaft, 7-packing ring, 8-support, 9-bearing, 10-bolt, 11-bolt, 12-bolt, 13-chip, 14-chip protection layer.
Referring to Fig. 1-Fig. 4, a kind of Magnetic Sensing Contactless Potentiometer is characterized in that: be to be made of magnet 1, magnetic receiver 3, bearing pedestal 4, chip 13 and protective layer 14 thereof; Wherein magnet 1 is to be fixed on the magnetic receiver 3 by bolt 10, magnetic receiver 3 is fixed on bearing pedestal 4 by bolt 12 again, bearing 9 is installed on the bearing pedestal 4 and between the two bearings 9 and is separated by packing ring 7, rotating shaft 6 is fixed on two bearings 9, support 8 is fixed on the bearing pedestal 4 by two bolts 11, in the centre of support 8 gathering magnet 5 is installed, the lower surface of gathering magnet 5 is fixed with the chip 13 that has chip protection layer 14; Shell 2 is to be fixed by closely cooperating between shell 2 and the bearing pedestal 4, and the top of shell 2 has two holes.
