Abstract

The utility model discloses a roller flat-head coupling device. A flat-head (3) of a through hole with an internal thread is sheathed on a roller end (1) which is provided with a threaded hole, the roller end (1) is connected with the flat-head (3) through a coupling bolt (4), and the roller end (1) and the flat-head (3) is fastened through a shim plate (2). The fabrication of the coupling device of the utility model is easy, and the flat-head is convenient to replace and can be used repeatedly. A roller is in front and back rolling, the abrasion and the deformation of the roller end, the flat-head and the shim plate are reduced, the cracking of the flat-head is avoided, and the service life of the flat-head is enhanced. The utility model can be used for the congener device of the metallurgy industry.

Description

Roll homalocephalus hookup mechanism

The utility model belong to clamp structure neck or, particularly roll homalocephalus jockey.

The steel rolling operation of metallurgical industry rolling mill; Be to give roll with transmission of power, to drive its rotation by the homalocephalus that is connected with roll.At present roll and homalocephalus ways of connecting have monoblock type that roll and homalocephalus are connected as a single entity and with roll and the homalocephalus assembled with backing plate employing matched in clearance.These connected modes have following deficiency: it is big that monoblock type is made difficulty of processing, and roll uses limitation, and homalocephalus is scrapped with the subscription rate of roll; Assembled is because the existence in roll end and homalocephalus gap, when roll carry out positive and negative when rolling, the easy to wear and crimp of homalocephalus and backing plate, it is frequent to cause backing plate to change, homalocephalus ftractures when serious, and homalocephalus is scrapped.

It is simple that the purpose of this utility model provides a kind of manufacturing, and homalocephalus is changed roll homalocephalus jockey convenient and that can use repeatedly.

For reaching above-mentioned purpose, the homalocephalus that the utility model will have the through hole of internal thread is enclosed within on the roll end that is provided with screw, with connecting bolt roll end is connected with homalocephalus, uses the backing plate wedging between roll end and the homalocephalus.

The one side of the utility model jockey backing plate is the inclined-plane, and another side is the plane.The inclined-plane of roll end both sides and the inclined-plane of backing plate fit.

The utility model jockey adopts connecting bolt that roll end is connected with homalocephalus, and homalocephalus is adorned, torn open conveniently, and homalocephalus can use repeatedly.Owing to use the backing plate wedging between roll end and the homalocephalus, eliminated its mutual gap, make roll positive and negative rolling in, roll end, homalocephalus, is out of shape and reduces greatly at the wearing and tearing of backing plate, has avoided the homalocephalus cracking, and improved the service life of homalocephalus greatly.

Fig. 1 is the structural representation of this jockey.

Wherein 1 is roll end, and 2 is backing plate, and 3 is homalocephalus, and 4 is connecting bolt.

Further specify the utility model jockey with embodiment below.The homalocephalus 3 that has the through hole of internal thread is enclosed within on the roll end 1 that is provided with screw, with connecting bolt 4 roll end 1 is connected with homalocephalus 3, for eliminating the gap between roll end 1 and the homalocephalus 3, with backing plate 2 wedgings.For the inclined-plane that makes roll end 1 both sides and the inclined-plane of backing plate 2 fit, the inclined-plane is processed in the two sides of roll end 1, the one side of backing plate 2 is processed into the inclined-plane, and another side is the plane.

Claims

1. roll homalocephalus jockey, comprise roll end (1), backing plate (2), homalocephalus (3), the homalocephalus (3) that it is characterized in that having the through hole of internal thread is enclosed within on the roll end (1) that is provided with screw, with connecting bolt (4) roll end (1) is connected with homalocephalus (3), uses backing plate (2) wedging between roll end (1) and the homalocephalus (3).

2. roll homalocephalus jockey according to claim 1, the one side that it is characterized in that backing plate (2) is the inclined-plane, another side is the plane.

3. roll homalocephalus jockey according to claim 1 is characterized in that the inclined-plane of roll end (1) both sides and the inclined-plane of backing plate (2) fit.
