Abstract
The utility model discloses a coupling device capable of preventing a shaft head from being abraded. The coupling device comprises a driving shaft (1) and a driven shaft (2), wherein a nested structure is in movable fit between the driving shaft (1) and the driven shaft (2). The coupling device is characterized in that the nested structure comprises an nested groove (4) arranged at the end of the driving shaft (1) or the driven shaft (2) and a nested flange (3) arranged at the end of the driven shaft (2) or the driving shaft (1), and abrasion-resistant pads are arranged on the sides of the nested groove (4) or the nested flange (3). The coupling device uses the abrasion-resistant pads to effectively protect a main body of a transmission shaft. If abrasion happens, only the abrasion-resistant pads are changed, and the service life of the transmission shaft is not affected. Furthermore, shutdown for a long time is avoided, a pair of abrasion-resistant pads can be replaced in a few minutes, production cost is reduced, and work efficiency is improved. The coupling device is simple in structure, stable and reliable in working and wide in application range and has popularization and application value.
Description
Technical field
The utility model belongs to field of mechanical technique, is specifically related to a kind of simple in structure, hitch bar that can prevent spindle nose wearing and tearing.
Background technique
In the existing technology, coaxial being in transmission connection of many machineries is that nested mode is direct-connected, and such as the lining machine of printing industry, the nested flange of its driven axle directly inserts in the nested groove of driving shaft, and rigidity is connected.In the working procedure, driving shaft rotates through the nested flange that nested groove blocks driven axle together, realizes power transmission.But because the existence of working clearance cause nested groove inboard, and the wearing and tearing of nested flange outer sides is bigger; The work that finally influences cooperates, and operational noise is bigger, and the working life of axle is shorter; Just need bearing to change if change, not only cost is high, and influence is produced.There is very big defective in obvious this fit system.For this reason, develop a kind of wearing and tearing that can effectively alleviate the part that is connected by shaft, the mode that prolongs transmission shaft working life is necessary.
The model utility content
It is a kind of simple in structure that the purpose of the utility model is to provide, and can prolong transmission shaft working life, reduces the hitch bar that can prevent the spindle nose wearing and tearing of user cost.
The purpose of the utility model is to realize like this; Comprise driving shaft, driven axle; Between described driving shaft and the driven axle be nested structure movingly; Described nested structure comprises the nested groove that is arranged at driving shaft or passive axle head and driven axle or the nested flange of axle head initiatively, and described nested groove or nested flange both sides are provided with wear-resistant pad.
The utility model adopts wear-resistant pad effectively to protect the transmission shaft body, even if wear and tear, also only needs to change wear-resistant pad, does not influence the working life of transmission shaft.And not needing long-time shutdown, a few minutes just can be changed one pair of wear-resistant pad, have not only lowered cost of production, and have improved work efficiency.The utility model is simple in structure, and working stability is reliable, and accommodation is extensive, has application value.
Description of drawings
Accompanying drawing is the utility model overall structure schematic representation;
Among the figure: 1-driving shaft, 2-driven axle, the nested flange of 3-, the nested groove of 4-, 5-wear-resistant pad, 6-set screw.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described, but never in any form the utility model is limited,, all belong to the protection domain of the utility model based on any conversion or the replacement that the utility model training centre is done.
Shown in accompanying drawing; The utility model comprises driving shaft 1, driven axle 2; Between described driving shaft 1 and the driven axle 2 be nested structure movingly; Described nested structure comprises the nested flange 3 of the nested groove 4 that is arranged at driving shaft 1 or driven axle 2 ends and driven axle 2 or driving shaft 1 end, and described nested groove 4 or nested flange 3 both sides are provided with wear-resistant pad 5.
Described wear-resistant pad 5 is fixed in the inboard of nested groove 4, and wear-resistant pad 5 and nested flange 3 are movingly.
Described wear-resistant pad 5 is fixed in the both sides of nested flange 3, and wear-resistant pad 5 and nested groove 4 are movingly.
Described wear-resistant pad 5 is the rigidity wear-resistant pad of high abrasion, is made by high manganese steel or wear-resisting alloy steel high-abrasive material.
Described wear-resistant pad 5 is the flexible wear-resistant pad of high abrasion, is made by nonmetallic wear-resistant materials such as teflon or nylon.
Described wear-resistant pad 5 is affixed through set screw 6 with nested groove 4 or nested flange 3.
Described wear-resistant pad 5 is affixed through adhesive means with nested groove 4 or nested flange 3.
The utility model working principle and working procedure:
The direct wearing and tearing that utilize wear-resistant pad 5 to isolate the transmission shaft body are in case wearing and tearing are as long as change wear-resistant pad 5.During use, wear-resistant pad 5 is fixed in the inboard of driving shaft 1 nested groove 4, when needing to change after the wearing and tearing, unclamps set screw 6, change new wear-resistant pad 5 and can recover proper functioning with set screw 6.
