Abstract

The utility model provides a cold tandem mill cydariform tooth transmission shaft roll side structure, includes the outer gear sleeve who is fixed in final drive shaft, the roller end axle sleeve of connecting the working roll, and the external diameter of transmission shaft outer gear sleeve junction is outer ring gear, and the junction of axle head axle sleeve is the ring gear, be provided with the intermediate tooth cover between transmission shaft outer gear sleeve and roller end axle sleeve, the intermediate tooth cover has ring gear and outer ring gear, the ring gear of intermediate tooth cover and transmission shaft outer gear sleeve's outer gear ring meshed, the outer ring gear of intermediate tooth cover and the ring gear meshing of roller end axle sleeve. Its advantage is the structure that adopts intermediate tooth cover to mesh final drive shaft and roller end axle sleeve respectively, can in time change when the intermediate tooth cover takes place wearing and tearing conveniently, avoided carrying out overall change and to the excessive maintenance of other spare parts to the internal tooth cover in the primary structure, labour saving and time saving, great saving spare parts expense and labour cost, more avoided having guaranteed product quality and production direct motion because the untimely rolling mill that causes of transmission shaft change vibrates aggravates.

Description

Cold continuous rolling barreled tooth flank power transmission shaft roll side structure
Technical field
This utility model is related to the power transmission arrangment of cold continuous rolling, particularly to a kind of cold continuous rolling barreled tooth flank power transmission shaft Roll side structure.
Background technology
In the drive system of cold continuous rolling, gear-box and working roll are to be rigidly connected, and power is by profile of tooth power transmission shaft from gear Case is driven to working roll, and transmission cooperation is closely.In actual production, from the point of view of on-site maintenance experience, major part is all roll The work odontotripsis ratio of side internal tooth casing is more serious, and other parts need not be changed.This internal tooth casing and roll use cooperatively, once abrasion Drive gap is excessive afterwards, so that rolling mill vibration is aggravated, the rate of wear can speed further, has a strong impact on making of transmission accuracy and equipment Use the life-span.Internal tooth and tooth cover for monolithic construction, on the one hand do not have the space of roll flute, the profile of tooth accuracy of manufacture has an impact, the opposing party Face tooth set gross weight is 370kg, after the flank of tooth lost efficacy, needs integral replacing tooth set, costly, dismounting difficulty is big.And internal tooth The set spare part order cycle is long, and the replacing of power transmission shaft needs to shut down more than 4 hours and just can carry out, and not only loses time, also makes Equipment is in the state of excessive maintenance, have impact on being smoothed out of production.In consideration of it, being necessary in milling train profile of tooth power transmission shaft Tooth set is reasonably transformed, to improve the cost pressure repaired in machine life-span and shortening maintenance time, reduction spare part of internal tooth casing Power.
Utility model content
The purpose of this utility model provides a kind of employing center tooth set to engage final drive shaft and roller end axle sleeve respectively Structure, can timely and conveniently be changed when center tooth set occurs abrasion, it is to avoid the internal tooth casing in original structure carried out Integral replacing and the excessive maintenance to other parts, time saving and energy saving, larger has saved spare part expense and labour cost, more keeps away Exempted from due to power transmission shaft change cause not in time rolling mill vibration aggravation it is ensured that product quality and produce direct motion cold continuous rolling Barreled tooth flank power transmission shaft roll side structure.
Solution of the present utility model is such that
A kind of cold continuous rolling barreled tooth flank power transmission shaft roll side structure, including the external tooth cover, the connection work that are fixed on final drive shaft Make the roller end axle sleeve of roller, the external diameter of described power transmission shaft external tooth cover joint is external toothing, the joint of described roller end axle sleeve is interior Gear ring;It is provided with center tooth set between power transmission shaft external tooth cover and roller end axle sleeve, described center tooth set has ring gear with outward Gear ring, the ring gear of described center tooth set is engaged with the external toothing of power transmission shaft external tooth cover, external toothing and roller that described center tooth covers The ring gear engagement of end axle sleeve.
More specifically technical scheme also includes: the number of teeth of the external toothing of described center tooth set and the ring gear of roller end axle sleeve is big The number of teeth, the external toothing of described center tooth set and roller end axle sleeve in the ring gear of center tooth set and the external toothing of power transmission shaft external tooth cover Ring gear modulus be less than center tooth set ring gear and power transmission shaft external tooth cover external toothing modulus.
The utility model has the advantages that engaging the structure of final drive shaft and roller end axle sleeve respectively using center tooth set, in centre Tooth set occurs can timely and conveniently be changed during abrasion, it is to avoid the internal tooth casing in original structure carried out with integral replacing and right The excessive maintenance of other parts, time saving and energy saving, larger has saved spare part expense and labour cost, more avoids due to transmission Axle change cause not in time rolling mill vibration aggravation it is ensured that product quality and produce direct motion.

Specific embodiment
The present invention includes the external tooth cover 1 being fixed on final drive shaft, the roller end axle sleeve 3 connecting working roll, outside described power transmission shaft The external diameter that tooth covers 1 joint is external toothing, and the joint of described axle head axle sleeve 3 is ring gear;In power transmission shaft external tooth cover 1 and roller end Be provided with center tooth set 2 between axle sleeve 3, described center tooth set 2 has ring gear and an external toothing, described center tooth set 2 interior Gear ring is engaged with the external toothing of power transmission shaft external tooth cover 1, and the external toothing of described center tooth set 2 is engaged with the ring gear of roller end axle sleeve 3. Wherein: the number of teeth of the external toothing of described center tooth set 2 and the ring gear of roller end axle sleeve 3 is more than ring gear and the biography of center tooth set 2 The number of teeth of the external toothing of moving axis external tooth cover 1, the modulus of the external toothing of described center tooth set 2 and the ring gear of roller end axle sleeve 3 is less than The modulus of the external toothing of the ring gear of center tooth set 2 and power transmission shaft external tooth cover 1.And it is somewhat larger to manufacture hardness.
