Abstract

A crank shaft comprises a spline end and crank handles connected at the end of the spline end. The crank shaft is characterized in that holes are formed on the crank handles, and the holes on the crank handles are communicated. The utility model has the advantages of good lubricating effect at the matched position, high cooling speed and long service life.

Description

A kind of bent axle

Technical field

The utility model relates to a kind of transmission device, particularly a kind of bent axle.

Background technique

Bent axle in the reciprocating pump of prior art, its crank place is stressed bigger, and therefore sliding bearing abrasion with matching is serious, needs frequently to change, and has caused the waste of a large amount of human and material resources, has increased cost of production, reduced manufacturing efficiency, and Security is not high.

The model utility content

The purpose of this utility model is to provide a kind of bent axle, and not only cooperation place high lubricating effect but also rate of cooling are fast for it, long service life.

Realize that the purpose of this utility model technological scheme is: a kind of bent axle comprises splined end and accepts thereafter crank that it is characterized in that: have the hole in the crank, the hole in each crank is interconnected.

And having oil gun to be arranged on the crank of bent axle end, this oil gun hole interior with being arranged on this crank is connected.

And described oil gun comprises body and is placed in seal cartridge on the body, in the gap of body and seal cartridge, have magnetic rings, friction ring and second round section joint ring vertically, circumference along magnetic rings is provided with groove, has first round section joint ring to be arranged in this groove.

And crank matches with sliding bearing, and is connected with pump case by the crankshaft bearing pressing plate.

And has oil pipe on the pump case.

Advantage of the present utility model is: 1. center and side oiling, high lubricating effect.2. rate of cooling is fast, reduces metal fatigue, long service life.

Description of drawings

Fig. 1 is the structural representation of bent axle.

Fig. 2 is the structural representation in each hole in the crank.

Fig. 3 is the structural representation of oil gun.

Embodiment

Referring to Fig. 1～3, the utility model is described further below with reference to embodiment.

Realize that the purpose of this utility model technological scheme is: a kind of bent axle comprises splined end 1 and accepts thereafter crank 2 that it is characterized in that: have hole 8 in the bent tenon 2, the holes 8 in each crank 2 are interconnected.

Splined end 1 is used for the moment of torsion of retarder is delivered on the bent axle.

Have hole 8 in the crank 2, the hole 8 in each crank 2 is interconnected.During work, lubricant oil is injected each crank 2 of flowing through successively under the driving of the eccentric force that lubricant oil produces, the purpose at place thereby lubricated 2 of the bent tenons of realization match when crank 2 rotations from oil gun 4.

Have hole 8 in the crank 2, the holes 8 in each crank 2 are interconnected, and can reach quick cooling purpose so that the heat that produces during bent axle work can in time distribute.

And having oil gun 4 to be arranged on the crank 2 of bent axle end, this oil gun 4 is connected with hole 8 in being arranged on this crank 2.

Further technological scheme can make described oil gun 4 comprise body 9 and be placed in seal cartridge 10 on the body 9, in the gap of body 9 and seal cartridge 10, have magnetic rings 13, friction ring 14 and second round section joint ring 12 vertically, circumference along magnetic rings 13 is provided with groove, has first round section joint ring 11 to be arranged in this groove.

During work, seal cartridge 10 and inner magnetic rings 13 thereof are rotated with bent axle with first round section joint ring 11, body 9, second round section joint ring 12 are fixed with oil gun 4 with friction ring 14, and friction ring 14 constitutes Seal cages with first, second round

section joint ring

11,12.

And crank 2 matches with sliding bearing 3, and is connected with pump case 7 by crankshaft bearing pressing plate 5.

Bent axle is connected with pump case 7 by crankshaft bearing pressing plate 5, can prevent its axial float when work, and less friction prolongs its working life.

Further technological scheme also can be to have oil pipe 6 on the pump case 7.

Oil pipe 6 oiling in pump on the pump case 7 can be lubricated crank 2 and rolling bearing 3, and less friction prolongs its working life.

Claims
