Abstract
The backlash compensation structure of a kind of knob, including housing, knob and spool, also includes tooth set, ripple pad and sliding sleeve, on knob medial wall, is radially provided with boss slider；On the positive and negative two sides of sliding sleeve, it is respectively arranged with the chute of arrangement in cross structure along its diametric(al)；Described slide block is corresponding with front runner position, and described slide block is inserted in the chute of front；Ripple pad is arranged between knob and sliding sleeve；Described ripple pad is circular configuration, and is arranged on the position between two slide blocks.This backlash compensation structure, it is mainly used in the assembly of knob, housing, spool, the version of cross chute is used between each parts, manufacture, the alignment errors such as Concentricity tolerance when each parts are installed, angular deviation can be compensated, on the premise of not affecting assembling effect, positioning datum, the problem such as concentricity of processing installed need not be considered, improve production efficiency, reduce the requirement on machining accuracy to part, reduce production cost.
Description
Technical field
This utility model relates to a kind of backlash compensation structure, the backlash compensation structure that a kind of spool, knob are special.
Background technology
In existing valve core structure, spool is arranged on enclosure interior, it is connected with knob by poppet shaft, in the course of processing, poppet shaft, insert body, housing etc. all can produce mismachining tolerance, install smoothly in order to ensure assembling process and good use feel, the machining accuracy of each part, benchmark and concentricity etc. require the highest, bring a lot of restriction condition to the course of processing, increase difficulty of processing, too increase production cost simultaneously.
Utility model content
This utility model is for the technological deficiency mentioned in background technology, it is provided that a kind of for spool, the backlash compensation structure of knob.
The technical solution adopted in the utility model is: the backlash compensation structure of a kind of knob, including valve body housing, knob and spool, also includes tooth set, ripple pad and sliding sleeve, wherein:
On described knob medial wall, its circumferencial direction is provided with slide block；On the positive and negative two sides of described sliding sleeve, it is respectively arranged with the chute of arrangement in cross structure along its diametric(al)；Described slide block is corresponding with front runner position, and described slide block is inserted in the chute of front；
Described ripple pad is arranged between knob and sliding sleeve；Described ripple pad is ellipsoidal structure, and is arranged on the position between two slide blocks.
Tooth set includes the cylindrical sleeve at middle part and to be fixed in cylindrical sleeve fixed plate below, cylindrical sleeve inner wall belt tooth, the structure of fixed plate and shape corresponding with the reverse side chute of sliding sleeve, and fixed plate is inlaid in reverse side chute.
Cylindrical sleeve is connected with the output shaft spline of spool.
This novel disclosed this backlash compensation structure, it is mainly used in the assembly of knob, housing, spool, the version of cross chute is used between each parts, manufacture, the alignment errors such as Concentricity tolerance when each parts are installed, angular deviation can be compensated, on the premise of not affecting assembling effect, positioning datum, the problem such as concentricity of processing installed need not be considered, improve production efficiency, reduce the requirement on machining accuracy to part, reduce production cost.
Accompanying drawing explanation
Fig. 1 is the structural representation after this utility model assembles.
Fig. 2 is exploded view of the present utility model.
In figure: knob 1, housing 2, tooth set 3, ripple pad 4, sliding sleeve 5, spool 6.
Detailed description of the invention
The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings.
See accompanying drawing 1-2, this novel disclosed this backlash compensation structure, it is mainly used in the package assembly between knob and housing, spool.
The backlash compensation structure of this knob, including knob 1, housing 2, tooth set 3, ripple pad 4, sliding sleeve 5, spool 6.Knob is the cap-shaped structure of spiral-lock, on its medial wall, is radially provided with boss slider.On the tow sides of sliding sleeve, it is respectively arranged with the chute of arrangement, i.e. front chute and reverse side chute in cross structure along its diametric(al).Slide block on knob is corresponding with front runner position, and slide block is inserted in the chute of front, and the two is inlaid in together.
Ripple pad is arranged between knob and sliding sleeve, and ripple pad is circular configuration, and is arranged on the position between two slide blocks.
Tooth set includes the cylindrical sleeve at middle part and is fixed in cylindrical sleeve fixed plate below, and fixed plate is to be respectively and fixedly connected to the bar shaped plate body of cylindrical sleeve both sides.Cylindrical sleeve inner wall belt tooth, the structure of fixed plate and shape are corresponding with the reverse side chute of sliding sleeve, and fixed plate is inlaid in reverse side chute.Cylindrical sleeve is connected with the output shaft spline of spool.
Knob can realize small-gap suture with the mating holes of housing and coordinate, it is ensured that during guest operation, turning moment is uniform, it is to avoid the problems such as clamping stagnation.The manufacture such as Concentricity tolerance, angular deviation, alignment error can be compensated by cross chute；Had a snack by ripple and repay left and right commutation, axial gap, it is ensured that use feel, the problem such as do not loosen, rock.
Knob, housing, ripple pad, cross chute, tooth set and the package assembly of spool, evade housing manufacturing tolerance, insert body mismachining tolerance, housing, insert body, the impact such as assembly error of spool, the problem such as the positioning datum that need not consider to install, the concentricity of processing.
Claims (3)
1. a backlash compensation structure for knob, including housing, knob and spool, it is characterised in that also include tooth set, ripple pad and sliding sleeve, wherein:
On described knob medial wall, radially it is provided with boss slider；On the positive and negative two sides of described sliding sleeve, radially it is respectively arranged with the chute of arrangement in cross structure；Described slide block is corresponding with front runner position, and described slide block is inserted in the chute of front；
Described ripple pad is arranged between knob and sliding sleeve；Described ripple pad is that circular configuration is the most flexible, and is arranged on the position between two slide blocks.
