Description
Technical field
The utility model is related to a kind of homalocephalus, and in particular to the special quick-changing type homalocephalus of roll.
Background technology
Roll is the instrument that (stocking) metal is made to generate plastic deformation, is to determine that rolling mill efficiency and the important of mill bar quality disappear
Consume component.Roll is the important part on steel rolling mill's rolling mill, and the pressure that is generated when being rolled using a pair of or one group of roll is rolled
Steel are ground, it is primarily subjected to Dynamic And Static Loads during rolling, abrasion and the influence of temperature change；The steel rolling behaviour of metallurgical industry rolling mill
Work is to impart power to roll by the homalocephalus being connected with roll, to drive roll rotation.
Traditional homalocephalus has problems in use：(1) centering is installed and requires high time length, roll change activity duration
It is long；(2) roll flat set and the connection bolt easy fracture of toe joint hand, cause equipment failure to shut down；(3) roll flat covers endoporus
Liner plate is absorbed impact when crossing steel, easily cuts bolt；(4) site environment causes that high temperature, water drenching, the oil sealing of routine is fragile, axis
It is fragile to hold poor lubrication, the replacement bearing activity duration is long, and outfit is various；(5) bounce is big when operating, the contracting of milling train service life
Short, steel rolling qualification rate reduces.
Utility model content
Technical problem to be solved in the utility model is the connection bolt of roll flat set and toe joint hand in traditional homalocephalus
Easy fracture causes equipment failure shutdown, and it is an object of the present invention to provide the special quick-changing type homalocephalus of roll, solves roll flat in traditional homalocephalus
The problem of connection bolt easy fracture of set and toe joint hand.
The utility model is achieved through the following technical solutions：
The special quick-changing type homalocephalus of roll, the toe joint hand coupled including roll flat set, with roll flat set, the toe joint hand
For centripetal toe joint hand, one end of the roll flat set is inserted into centripetal toe joint hand, and roll flat set has with centripetal toe joint hand
Identical central shaft, roll flat covers passes through Flat dey joint between the part being inserted into inside centripetal toe joint hand and centripetal toe joint hand.
