Abstract
The utility model provides an intermediate shaft structure of a retarder. The intermediate shaft structure comprises spline sections at the two ends of the intermediate shaft structure, and two stop nuts. External threaded sections are arranged at the outer ends of the spline sections, the two stop nuts are connected with the external threaded sections respectively through threads, and the inner end of each stop nut is provided with a radial annular protrusion. Compared with the prior art, threaded holes do not need to be formed in end cover flanges, so that machining processes are reduced, and installing and dismounting are both convenient.
Description
Technical field
The utility model relates to a kind of component of retarder, especially a kind of intermediate shaft structure of retarder.
Background technique
Retarder is a kind of device for car auxiliary brake, and the jack shaft of retarder is the critical component that connects retarder rotor and rotor frame, and rotor frame is to be rotationally connected by two bearings and jack shaft, bearing is against on bearing by two ends end cap flange separately, placement bearing moves axially, common end cap flange is to get on the bus and make two tapped holes at jack shaft, then by two screws, be connected with the end thread of jack shaft, although this structure is feasible, but more loaded down with trivial details in installation process, and dismounting is inconvenient.
Summary of the invention
The purpose of this utility model is to provide a kind of intermediate shaft structure of the retarder safeguarded of being easy for installation and removal.
In order to achieve the above object, the technical solution of the utility model is: a kind of intermediate shaft structure of retarder, comprises and the spline segment at two ends also comprise two stop nut, the outer end of described spline segment is equipped with external thread section, and two stop nut are threaded with external thread section respectively.
The inner of described stop nut is provided with radial ringed projection.
Adopt said structure, owing to also comprising two stop nut, the outer end of described spline segment is equipped with external thread section, two stop nut are threaded with external thread section respectively, therefore when two end cap flanges of assembling, as long as by stop nut separately, just end cap flange can be tight against on bearing, prevent the axial float of bearing, and mount and dismount very convenient.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is use phase diagram of the present utility model.
Embodiment
The embodiment who provides below in conjunction with accompanying drawing is described in further detail the utility model.
Shown in Figure 1, a kind of intermediate shaft structure of retarder, comprises and the spline segment 1 at two ends also comprises two stop nut 2, the outer end of described spline segment 1 is equipped with 3, two stop nut 2 of external thread section and is threaded with external thread section 3 respectively.
Shown in Figure 1, in order better stop nut 2 and end cap flange to be tight against, the inner of described stop nut 2 is provided with radial ringed protruding 2-1.
Shown in Figure 2, when the utility model is installed, after rotor frame 4 is arranged on jack shaft by two bearings 5, end cap flange 6 is sleeved on jack shaft, then by two stop nut 2, tightens, end cap flange 6 is tight against on bearing 5, prevent bearing 5 axial floats, compared with prior art, without the tapped hole processed of getting on the bus at end cap flange 6, reduce manufacturing procedure, and installation and removal are all very convenient.
Claims (2)
