Abstract
The utility model relates to a gear feedback mechanism connected by a sliding block spring which is applied to the electric operating mechanism of industrial automatic instrument. The utility model comprises a connecting board (5); one end of the connecting board (5) is provided with a U type groove; a sliding block (4) is arranged flexibly on the connecting board (5) through the U type groove; the two ends of a spring (7) are respectively connected with the sliding block (4) and the connecting board (5); the sliding block (4) is provided with a through hole; a regulation resistance (6) is fixed on the sliding block (4) through the through hole; the shaft of the regulation resistance (6) through the through hole is sleeved with a tetrafluoride sleeve (3); a feedback gear (2) is fixed on the tetrafluoride sleeve (3) through a stopping ring (1). The utility model fulfills the normal working requirements, avoids the axial movement and radial swinging of the feedback gears, at the same time, avoids the dropping of the gear when the breakdown happens or installing or exchanging the gears thereby protecting the regulation resistance and improving the reliability of the operating mechanism.
Description
Technical field
The utility model relates to the gear feedback mechanism that a kind of sliding block spring formula that is mainly used in industrial automation control instrument electric actuator connects.
Background technique
Fix by mounting plate for common feedback element as shown in Figure 1, rely on the elasticity of shell fragment to make feedback gear and corresponding tooth bar engagement, thus the gear feedback mechanism that constitutes.
There is following defective in the gear feedback mechanism of this form:
1) gap of hinge is bigger, takes off tooth when causing the feedback gear engagement easily;
2) when changing feedback gear, easily make excessive the following the string of pivot angle of shell fragment, cause feedback gear to break away from the tooth bar that is engaged with;
3) feedback gear axial runout is bigger.
The model utility content
The purpose of this utility model provides a kind of actuator that can make and debugs conveniently, improve the reliability of gear engagement, and gear is installed, change applicability, and avoid the feedback gear axial float, gear feedback mechanism that the sliding block spring formula that radially wobbles connects.
The technical solution of the utility model is:
The gear feedback mechanism that a kind of sliding block spring formula connects, its specialization is, comprise a plate, be provided with U type groove at this connecting plate one end, a slide block slidably is installed on the connecting plate by this U type groove, and the two ends of a spring are connected on slide block and the connecting plate, on slide block, have through hole, potentiometer passes this through hole and is fixed on the slide block, potentiometer pass through hole the axle on be set with the tetrafluoro lining, feedback gear is fixed on this tetrafluoro lining by collar.
Wherein the part that contacts with U type groove two parallel edges of connecting plate on slide block is provided with chute separately.
Wherein the one side away from connecting plate U type groove is provided with a depression on slide block, also is being provided with a depression on the end away from U type groove on the connecting plate, and described both ends of the spring is stuck in above-mentioned two recess.
Further, wherein said spring is " 6 " shape.
Wherein potentiometer is fixed on the slide block by a nut.
Further, wherein connecting plate is " L " shape, and described U type groove is positioned on the connecting plate on long one section, has a slotted hole on short one section of connecting plate.
To have now in the utility model to adopt and become the connection of sliding block spring formula being connected of shell fragment and hinge; slide block is processed as chute in the side up and down; be stuck in the connecting plate; elastic force by spring makes feedback gear and tooth bar engagement; the needs of proper functioning had both been satisfied; avoided again feedback gear axial float, radially wobble; really eliminated gear axial float, radially wobble the gap; avoided simultaneously under situations such as fault, installation, replacing, taking off tooth; conscientiously protect costly potentiometer, improved the reliability of actuator greatly.Adopt the technical solution of the utility model, the connecting plate fixed form is a chute-type, behind stroke replacing feedback gear, only need loosening connecting plate set screw, moving connecting plate according to the size of feedback gear along the radial direction of feedback gear gets final product, elastic force by spring makes gear engagement more reliable, and debugging is accurately shortened debug time.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model background technique;
Accompanying drawing 2 is a structural representation of the present utility model;
