Abstract

The invention discloses a stirring shaft, which comprises a driving shaft driven by a motor, a driven shaft and a transmission chain. The transmission chain comprises a plurality of groups of link parts connected in a cross mode through pins, each linked part is formed by an outer link plate and a middle link plate, the outer link plates are fixedly installed on the pins, and the middle link plates are installed on the pins and can rotate relative to the outer link plates. A first gear is fixed on the periphery of the end portion of the driving shaft, a second gear is fixed on the periphery of the end portion of the driven shaft, four groups of link parts are connected through one pin, the first gear is installed between two groups of link parts in a matched mode, the second gear is installed between the other two groups of link parts in a matched mode, and an electrode is connected with a speed changing box controlling the driving shaft. By means of the stirring shaft, the service life of devices is prolonged.

Description

A kind of shaft

Technical field

The present invention relates to a kind of shaft.

Background technology

Power transmission shaft is impaired easily in long-term rotation process, and long to some axial lengths especially power transmission shaft very easily produces more serious consequence, uses some occasions than the long pass moving axis for needs; Such as agitator etc., the way of prior art is to use connector that two power transmission shafts are fixed; And rotate synchronously, in actual use, damaged part mainly occurs on its connector; Yet, though this way can be keeped in repair the service life that increases power transmission shaft through changing connector; The general employing is connected firmly between connector and two power transmission shafts, and when connector was impaired, the binding site of power transmission shaft and connector was same easy to be impaired; And the impaired of connector also can addition, increases maintenance cost, demands urgently improving.

Summary of the invention

Problem to prior art exists the objective of the invention is to propose a kind of shaft, can increase the service life of equipment.

For reaching this purpose, the present invention adopts following technical scheme:

A kind of shaft comprises driving shaft, driven axle, driving-chain through driven by motor, and said driving-chain comprises the many groups link member that links to each other through the bearing pin intersection; Said link member is made up of outer chain connecting plate, intermediate chain fishplate bar; Said outer chain connecting plate is fixedly mounted on the said bearing pin, and said intermediate chain fishplate bar is installed on the said bearing pin, and said intermediate chain fishplate bar can rotate with respect to said outer chain connecting plate; Said driving shaft end periphery fixed gear; Said driven axle end periphery fixed gear, a said bearing pin connects four groups of said link member, and said gear matched is installed between two groups of said link member; Said gear matched is installed between other two groups of said link member, and said electrode connects the gearbox of the said driving shaft of control.

Said outer chain connecting plate is riveted on the said bearing pin.

Said outer chain connecting plate is thinner than said intermediate chain fishplate bar.

The rigidity of said outer chain connecting plate is less than the rigidity of said intermediate chain fishplate bar.

Based on disclosing of above technical scheme, the present invention possesses following beneficial effect:

Driving-chain among the present invention has certain cushioning effect, and driving shaft drives driven axle through driving-chain and rotates, and can reduce the damage to driving shaft and power transmission shaft, thereby increases service life of equipment.。

The specific embodiment

Further specify technical scheme of the present invention below in conjunction with accompanying drawing and through the specific embodiment:

Embodiment 1

Propose a kind of shaft, comprise the driving shaft 21, driven axle 31, the driving-chain 1 that drive through motor 4, driving-chain 1 comprises the many groups link member 11 that links to each other through bearing pin 14 intersections, link member 1

1 is made up of outer chain connecting plate 12, intermediate chain fishplate bar 13; Outer chain connecting plate 12 is fixedly mounted on the bearing pin 14, and intermediate chain fishplate bar 13 is installed on the bearing pin 14, and intermediate chain fishplate bar 13 can rotate with respect to outer chain connecting plate 12; Driving shaft 21 end periphery fixed gears 22; 32, bearing pins of driven axle 31 end periphery fixed gears 14 connect four groups of link member 111,112,113,114, gear 22 cooperate be installed in two groups of link member 111, between 112; Gear 32 cooperate be installed in other two groups of link member 113, between 114, electrode 4 connects the gearbox 5 of control driving shafts 21.Outer chain connecting plate 12 is riveted on the bearing pin 14.Outer chain connecting plate 12 is thinner than intermediate chain fishplate bar 13.The rigidity of outer chain connecting plate 12 is less than the rigidity of intermediate chain fishplate bar 13.

Electrode 4 cooperates gearbox 5 control driving shafts 21 to rotate, and wherein, gearbox 5 plays buffering and regulating action; Driving shaft 21 driven gears 22 rotate, and gear 22 cooperations are installed between link member 111 and the link member 112, thereby drive link member 111 and link member 112; Because link member 111,112,113,114 is installed on the bearing pin 14, link member 111 is rotated and can drive link member 113 be rotated with link member 114 with link member 112, is installed between link member 113 and the link member 114 because gear 32 cooperates; Link member 113 is rotated and can be rotated by driven gear 32 with link member 114; And gear 32 is fixed on the driven axle 31, rotates thereby drive driven axle 31, thereby realizes that driving shaft 21 rotates drive driven axle 31 and rotates; Because driving-chain 1 has certain cushioning effect; Driving shaft 21 drives driven axle 31 through driving-chain 1 and rotates, and can reduce the damage to driving shaft 21 and power transmission shaft 31, can increase service life of equipment.

The above; Be merely the preferable specific embodiment of the present invention; But protection scope of the present invention is not limited thereto; Any technical staff who is familiar with the present technique field is equal to replacement or change according to technical scheme of the present invention and inventive concept thereof in the technical scope that the present invention discloses, all should be encompassed within protection scope of the present invention.
