Abstract
The utility model relates to a retardance device part, and especially relates to a retarder middle shaft. The retarder middle shaft comprises spline shaft sections on the two ends of the retarder middle shaft, wherein the middle section of the shaft is provided with two bearing stop bosses, a groove is formed between the two bosses, and the two end faces of the shaft are provided with two screwed holes; and the spline shaft sections on the two ends of the retarder middle shaft are respectively provided with a mark on one of the spline teeth on the two faces of the spline shaft sections, and the spline teeth with the marks on the two ends of the shaft are aligned. The retarder middle shaft provided by the utility model has the advantages that the installation is simple and convenient, the rotation is not easy, and a relaxing effect is good.
Description
Technical field
The utility model relates to a kind of retarding device parts, particularly a kind of retarder jack shaft.
Background technique
Retarder is a kind of device for car auxiliary brake, along with the speed of automobile is more and more faster, the brake load of automobile is also increasing, on the automobile that particularly travels in the frequent local bus that stops and mountain area, the excessive problem of brake load is more outstanding, if these brake loads are all born by service braking sytem, will cause brake drum and brake strip overheated, thereby cause the braking efficiency to descend, even stopping power complete obiteration.
The retarder jack shaft is the critical component that connects rotor, general retarder rotor passes through spline, be installed on the retarder jack shaft, with big nut itself and retarder jack shaft are fixed again, frequent when automobile brake, load is excessive, or when jolting, nut is very easily loosening, cause hidden danger, affected the Safety performance of braking system.
Summary of the invention
The utility model provides a kind of installation simple and convenient, is difficult for rotating the retarder jack shaft that relaxation effect is good.
For achieving the above object, the technical solution adopted in the utility model is: a kind of retarder jack shaft, comprise the splined shaft section at two ends, and its innovative point is: the stage casing of axle is provided with two bearings gear boss, forms grooves in the middle of two boss; The both ends of the surface of axle respectively are provided with two tapped holes.The splined shaft section at described two ends all be provided with a mark on a spline tooth of both ends of the surface, and the markd spline tooth of the tool at axle two ends aligns.
After adopting said structure, because the both ends of the surface of retarder jack shaft are provided with two tapped holes, can pass through two bolts and a pressing plate during use, the adpting flange with the spline teeth groove that will be connected with rotor compresses, and installation is simple, convenient, after the locking, be difficult for becoming flexible, anti-loosing effect is good.
Description of drawings
The embodiment who provides below in conjunction with accompanying drawing is described in further detail the utility model.
Fig. 1 is the structural representation of the utility model retarder jack shaft;
Fig. 2 is that C among Fig. 1 is to view.
Embodiment
Referring to Fig. 1, a kind of retarder jack shaft comprises the splined shaft section 1 at two ends, and its innovative point is: the stage casing of axle forms grooves 3 in the middle of being provided with 2, two boss of two bearings gear boss 2; The both ends of the surface of axle respectively are provided with two tapped holes 4.The splined shaft section 1 at described two ends all be provided with a circular mark 5 on a spline tooth of both ends of the surface, and the spline tooth with mark 5 at axle two ends aligns.
As long as will fix with flange and the retarder jack shaft of spline teeth groove during use, at first with markd spline tooth alignment on flange and the jack shaft, the spline teeth groove of flange inserts on the splined shaft section 1 at retarder jack shaft two ends, then with two bolts and a pressing plate axle head that flange screw is fixed on the retarder jack shaft is got final product, install simple, convenient, be difficult for after the locking becoming flexible, anti-loosing effect is good.
