Abstract
The utility model belongs to the field of braking gap manual adjusting arm assemblies, and particularly relates to a direct-arm worm device of a manual adjusting arm. The direct-arm worm device comprises a direct arm, wherein the direct arm is connected with a worm wheel and a worm; the worm and a worm pin have split structures; and the worm wheel is provided with a square hole for installing the worm and a cylindrical hole for installing the worm pin. Separate processing can be performed, so that the processing difficulty of an adjusting direct arm is lowered greatly, and the processing cost is saved.
Description
Technical field
The utility model belongs to brake clearance manual adjusting arm assembly field, relates in particular to a kind of endless screw apparatus of hand regulation arm of straight arm type.
Background technique
Brake clearance adjustment arm is applicable to drum brake more, links to each other with the push rod of brake chamber.Because frequent brake, the gap that can cause brake shoe and brake drum is that the braking ability of car load reduces greatly owing to the wearing and tearing of friction plate strengthen; So being exactly gap through the adjustment break, the effect of adjustment arm guarantees the safety of driving a vehicle; Wherein adjust arm and mainly be divided into hand regulation arm and adjust arm automatically, hand regulation arm needs automobile behind the certain mileage of operation, the abrasion condition of hand inspection break; Gap through adjustment arm manual adjustment brake arm; Existing manual adjustment arm configuration more complicated is difficult for manufacturing, the bad grasp of precision when assembling simultaneously.
The model utility content
The purpose of the utility model provides a kind of be convenient to processing, manufacturing, and is simple in structure, practices thrift the straight arm type hand regulation arm endless screw apparatus of processing cost.
For achieving the above object; The technological scheme of the utility model is: straight arm type hand regulation arm endless screw apparatus, comprise straight-arm, and straight-arm connects turbine, worm screw; Described worm screw and worm screw pin are split-type structural, and turbine is provided with the square opening of an installation worm and the cylindrical hole of an installation worm pin.
When adopting technique scheme; In the utility model, described worm screw and worm screw pin are split-type structural, so just can be with worm screw, worm screw pin separate machined; Greatly reduce the difficulty of processing of adjustment straight-arm like this; Practice thrift processing cost, during installation, only need on turbine, process the square opening of an installation worm and the cylindrical hole of an installation worm pin.
Further, because when assembling, need certain pressure, the worm screw pin is press fit in the worm screw, worm screw and worm screw pin adopt Spielpassung, and the worm screw pin can easierly be pressed into worm screw, can not cause wearing and tearing and the distortion of worm screw.
Further, because worm screw and worm screw pin Spielpassung, so on the worm screw pin, be provided with spline, the worm screw pin can not cause worm screw and worm screw pin to skid because of the engagement between worm screw and the turbine after being press fit into worm screw yet like this.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is done further detailed explanation:
Fig. 1 is the structural representation of the utility model straight arm type hand regulation arm endless screw apparatus;
Fig. 2 is the spline sectional view of the utility model straight arm type hand regulation arm endless screw apparatus.
Embodiment
As shown in Figure 1; The utility model straight arm type hand regulation arm endless screw apparatus comprises straight-arm 1, and straight-arm connects turbine 2, worm screw 3, and described worm screw 3 is a split-type structural with worm screw pin 4; Turbine 2 is provided with the square opening 6 of an installation worm 3 and the cylindrical hole 5 of an installation worm pin 4; Described worm screw 3 is sold 4 Spielpassung with worm screw, and is as shown in Figure 2, and worm screw pin 4 is provided with spline 7.
Add man-hour like this, can worm screw 3 opened with the worm screw pin in 4 minutes and carry out processing and fabricating, not only greatly reducing the difficulty of processing of adjustment straight-arm; Also practice thrift processing cost, when mounted, only need on turbine 2, process the square opening 6 of an installation worm 3 and the cylindrical hole 5 of an installation worm pin 4; Assurance is in place worm screw 3, worm screw pin 4, and worm screw 3 can also divide into groups through the size of tolerance with worm screw pin 4 simultaneously, utilizes the grade of tolerance selectively to install; Turbine 2, worm screw 3, worm screw pin 4 installation precision each other are higher relatively like this; In addition because when being press fit into worm screw pin 4 in the worm screw 3, need certain pressure, so worm screw 3 is adopted Spielpassung with worm screw pin 4; Worm screw pin 4 can easierly be pressed into worm screw 3; Can not cause wearing and tearing and the distortion of worm screw 3, in addition because worm screw 3 is sold 4 Spielpassung with worm screw, so on worm screw pin 4, be provided with spline 7; Worm screw pin 4 can not cause worm screw 3 and worm screw pin 4 to skid because of the engagement between worm screw 3 and the turbine 2 after being press fit into worm screw 3 yet like this.
Above-described only is the preferred implementation of the utility model; Should be pointed out that for a person skilled in the art, under the prerequisite that does not break away from the utility model structure; Can also make some distortion and improvement; For example: the size of square opening 6, the diameter of cylindrical hole 5, the specification of spline 7 etc.These also should be regarded as the protection domain of the utility model, and these can not influence effect and practical applicability that the utility model is implemented.
