Abstract
The utility model belongs to the improvement of a rough rolling cardan shaft flange yoke structure in a bar steel mill, and particularly provides an improved cardan shaft flange yoke of a rough rolling mill. The improved cardan shaft flange yoke of the rough rolling mill comprises a cardan shaft flange yoke body, wherein an intermediate shaft joint spider is connected with the cardan shaft flange yoke body through a cross assembly, and the thickness of a flange plate of the cardan shaft flange yoke body is 50mm. The improved cardan shaft flange yoke of the rough rolling mill is reasonable in structure, high in strength and anti-fatigue performance, and strong in impact load resisting capacity.
Description
Technical field
The utility model belongs to the universal drive shaft flange crotch of the improvement, particularly a kind of improved roughing milling train of rolled bar steel mill roughing universal drive shaft flanged yoke shelf structure.
Background technology
Intrinsic roughing rolling mill universal shaft flange crotch impacts through long-term load, and average 4 months with regard to the fracture accident.Main existing problems:
1, roughing steel billet in the operation of rolling is crossed steel to the impact load long-term existence of universal drive shaft.2, flange crotch final fracture all is to be caused by the expansion of initial fatigue crack point, and these fatigue crack source points are basically all at flange crotch stress concentration point, and wherein the side keyway place is the most obvious.3, through checking, roughing universal drive shaft flange crotch intensity is less than normal, causes universal drive shaft short service life.4, the sudden fracture accident of universal drive shaft is many.5, change 1 universal drive shaft operation and need 4 people 6 hours.It is about 4 months only that the universal drive shaft fatigue fracture causes service life, the parking that causes the accident, and output reduces, and cost of labor increases.
Summary of the invention
The purpose of this utility model is to provide a kind of universal drive shaft flange crotch of improved roughing milling train, and it is rational in infrastructure, and intensity is high, and anti-fatigue performance is high, and the resistance to shock loads ability is strong.
The purpose of this utility model is achieved in that a kind of universal drive shaft flange crotch of improved roughing milling train, comprises the universal drive shaft flange crotch that jackshaft cross jaw connects by cross assemble, and the flange thickness of universal drive shaft flange crotch is 50mm.
For the flange crotch fatigue fracture that overcomes former universal drive shaft has limited the serviceability rate of universal drive shaft on production line, the utility model provides a kind of more rational roughing universal drive shaft flange crotch, solves the problem of former universal drive shaft flange crotch easy fracture.
The technical scheme that the utility model solves the flange crotch fatiguability fracture of former universal drive shaft is: check in conjunction with site technique intensity through analysis and universal drive shaft flange crotch that universal drive shaft lost efficacy, according to checking conclusion, universal drive shaft flange crotch flange thickness size increases to 50mm by former 40mm, improves thus upper flange crotch antifatigue and shock loading ability.
The utility model is rational in infrastructure, and intensity is high, has improved anti-fatigue performance, has strengthened the resistance to shock loads ability.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described, Fig. 1 is main TV structure schematic diagram of the present utility model, and Fig. 2 is the left TV structure schematic diagram of Fig. 1.
The specific embodiment
A kind of universal drive shaft flange crotch of improved roughing milling train as shown in Figure 1 and Figure 2, comprises the universal drive shaft flange crotch 3 that jackshaft cross jaw 2 connects by cross assemble 1, and ring flange 4 thickness of universal drive shaft flange crotch 3 are 50mm.
Claims (1)
1. the universal drive shaft flange crotch of an improved roughing milling train, comprise the universal drive shaft flange crotch (3) that jackshaft cross jaw (2) connects by cross assemble (1), it is characterized in that: ring flange (4) thickness of universal drive shaft flange crotch (3) is 50mm.
