Abstract
The utility model disclose a improved novel supporting generator shaft, which comprises a the supporting shaft; the one end of the supporting shaft is provided with a joint part which is fixed on and connected with a gear room of the diesel engine; the joint part and the supporting shaft are in structure of a ladder-shaped shaft; the diameter of the joint part is smaller than that of the supporting shaft; the joint part is provided with joint screw threads; when in installation, the joint part can be connected to the gear room through the joint screw threads; and the raising height of the shaft can be controlled by the shoulder of the ladder-shaped shaft, thereby without a special structure to control and easy to be replaced and maintained, greatly reducing the expense of the maintenance and the using costs.
Description
Technical field
The present invention relates to a kind of back shaft that on diesel engine, is used to install generator.
Background technique
As shown in Figure 3, the back shaft of diesel generator is to be connected support by the interference fit with the gear chamber hole, finish installation by interference fit between for example former WD615.X46 diesel generator back shaft and the gear chamber hole, this just need have relatively high expectations to the surface roughness in axle and hole, need adopt the protrusion height of special tooling Control Shaft simultaneously, in case and damage then must pull down gear chamber and could change, make the inconvenience of keeping in repair ten minutes, maintenance expenses is higher.
Summary of the invention
Technical problem to be solved by this invention provide a kind of can be for convenience detach and the improved generator back shaft of maintenance.
For solving the problems of the technologies described above, technological scheme of the present invention is: improved generator back shaft, comprise the back shaft body, one end of described back shaft body is provided with the joint of fixedlying connected with the diesel engine gear chamber, described joint becomes the multidiameter shaft structure with described back shaft body, the diameter of described joint is less than the diameter of described back shaft body, and described joint is provided with connecting thread.
As a kind of improvement, the end of described joint is provided with does not have the cylndrical surface of screw thread part;
As further improvement, described axis body be provided with two can described axis body for convenience detach planar surface portion;
As further improvement, the outer end of described back shaft body is provided with screw hole.
Owing to adopted technique scheme, improved generator back shaft, comprise the back shaft body, one end of described back shaft body is provided with the joint of fixedlying connected with the diesel engine gear chamber, described joint becomes the multidiameter shaft structure with described back shaft body, the diameter of described joint is less than the diameter of described back shaft body, described joint is provided with connecting thread, when mounted, joint is connected by screw thread with described gear chamber, and comes the protrusion height of Control Shaft, thereby do not need to adopt special tooling to control by the shaft shoulder of multidiameter shaft, and be convenient for changing and keep in repair, greatly reduce the expense and the user cost of maintenance.
Description of drawings
Fig. 1 is the structural representation of the embodiment of the invention;
Fig. 2 is the plan view of Fig. 1;
Fig. 3 is the structural representation for background technique.
Embodiment
As depicted in figs. 1 and 2, improved generator back shaft, comprise back shaft body 1, one end of described back shaft body 1 is provided with the joint 3 of fixedlying connected with diesel engine gear chamber 2,1 one-tenth multidiameter shaft structure of described joint 3 and described back shaft body, the diameter of described joint 3 is less than the diameter of described back shaft body 1, it is the so-called shaft shoulder, and come the protrusion height of Positioning Gear chamber 2 by the shaft shoulder, described joint 3 is provided with connecting thread, the end of described joint 3 is provided with does not have the cylndrical surface of screw thread part, prevents that screw thread is not easy to install after damage; Described axis body 1 be provided with two can described axis body 1 for convenience detach planar surface portion 4, be convenient to the installation and removal of back shaft; The outer end of described back shaft body 1 is provided with screw hole 5.
During installation, the joint 3 of described back shaft body 1 is twisted in the tapped hole corresponding on the newborn described gear chamber 2, because in back shaft processing, the position of the shaft shoulder is to locate according to the protrusion height of gear chamber 2, so when the protrusion height of fixed described gear chamber 2, just do not need to locate with special frock tool; After described back shaft all installed, the tapped hole of the outer end by described back shaft body 15 installed motor; If described back shaft need be changed or keep in repair, then a need screw off it and get final product.
