Abstract
A diesel starting crank comprises a crank shaft and a sleeve pipe sleeved on the crank shaft; steel balls are arranged between the crank shaft and the sleep pipe and around the crank shaft; steel ball slots are arranged on the inner walls of the crank shaft and the sleeve pipe corresponding to the steel balls; a steel ball entrance with inside screw thread is arranged on the sleep pipe corresponding to the steel ball slots; the inside of a close cover with outside thread on the steel ball entrance is shaped like an arc. The utility model is easy, flexible and labor saving for use and is extended in service life to a large extend.
Description
The utility model relates to a kind of diesel engine starting device, particularly a kind of diesel engine starting crank.
The diesel engine starting crank that uses in the prior art, its structure is, sleeve pipe of socket on the crank axle, sleeve pipe is made by thin gauge conduit, during use, and sleeve pipe and the strong friction of the direct occurrence of large-area of crank axle, sleeve pipe is easy to damage or come off from the crank axle, thereby cause the diesel engine starting difficulty, and after the start crank damage, be difficult for repairing voluntarily.
The purpose of this utility model is at the deficiencies in the prior art, and a kind of diesel engine starting crank flexible, long service life that rotates is provided.
The purpose of this utility model is to realize by following technological scheme.A kind of diesel engine starting crank, comprise the crank axle, be enclosed within the sleeve pipe on the crank axle, it is characterized in that, be provided with the steel ball of ring crank axle between crank axle and the sleeve pipe, with the inwall of the outer wall of the crank axle of steel ball corresponding part and sleeve pipe on be provided with steel bead groove, be provided with tapped steel ball inlet with the sleeve pipe of steel bead groove corresponding part, the inboard that is provided with the capping of externally threaded steel ball inlet is an arc.Like this, during use, steel ball can reduce the friction between crank axle and the sleeve pipe, rotates flexibly, and simultaneously, steel ball can also play the effect of yoke in steel bead groove, makes sleeve pipe be difficult for coming off from the crank axle.
The purpose of this utility model can also further realize by following technological scheme.The above diesel engine starting crank is characterized in, sleeve pipe is that wall thickness is the steel pipe of 3-5mm.
Compared with prior art, the utility model is owing to be provided with the steel ball that rubs between minimizing crank axle and the sleeve pipe between crank axle and the sleeve pipe, so use light and handy, flexible, laborsaving, steel ball can also play the effect of yoke in steel bead groove, make sleeve pipe be difficult for coming off, prolonged the working life of start crank greatly from the crank axle.
Fig. 1 is the sectional view of the utility model diesel engine starting crank.
Fig. 2 is the sectional view of the A-A section of Fig. 1.
Contrast accompanying drawing below, further specify technology implementation scheme of the present utility model.
Embodiment one.With reference to Fig. 1, Fig. 2.A kind of diesel engine starting crank, comprise crank axle 3, be enclosed within the sleeve pipe 4 on the crank axle 3, be provided with the steel ball 2 of ring crank axle 3 between crank axle 3 and the sleeve pipe 4, present embodiment is provided with two circle steel balls, with the inwall of the outer wall of the crank axle 3 of steel ball 2 corresponding parts and sleeve pipe 4 on be provided with steel bead groove 1, be provided with tapped steel ball inlet 6 with the sleeve pipe 4 of steel bead groove 1 corresponding part, the inboard that is provided with the capping 5 of externally threaded steel ball inlet 6 is an arc.During use, steel ball can reduce the friction between crank axle and the sleeve pipe, and steel ball can also play the effect of yoke in steel bead groove, makes sleeve pipe be difficult for coming off from the crank axle, it is light and handy, flexible, laborsaving that the utility model uses, and prolonged the working life of start crank greatly.
Embodiment two.Above-described a kind of diesel engine starting crank, its sleeve pipe 4 are that wall thickness is the steel pipe 4 of 3mm.
Embodiment three.With reference to Fig. 1, Fig. 2.A kind of diesel engine starting crank, comprise crank axle 3, be enclosed within the sleeve pipe 4 on the crank axle 3, sleeve pipe 4 is that wall thickness is the steel pipe 4 of 5mm, be provided with the steel ball 2 of ring crank axle between crank axle 3 and the sleeve pipe 4, present embodiment is provided with three circle steel balls, with the inwall of the outer wall of the crank axle 3 of steel ball 2 corresponding parts and sleeve pipe 4 on be provided with steel bead groove 1, be provided with tapped steel ball inlet 6 with the sleeve pipe 4 of steel bead groove 1 corresponding part, the inboard that is provided with the capping 5 of externally threaded steel ball inlet 6 is an arc.
