Abstract
The utility model discloses a rotational structure capable of sliding axially. The rotational structure consists of a bearing block, ball bearings, central shaft sleeves, a transmission shaft and a driving gear. The rotational structure is characterized in that ball bearing mounting through holes are formed in two vertical lugs of the bearing block respectively, a central through hole of each ball bearing is in close fit with each central shaft sleeve provided with a regular-polygon-shaped inner hole, the transmission shaft with a corresponding regular-polygon-shaped cross section sequentially penetrates through the central shaft sleeve on the first vertical lug, a central through hole of the driving gear and the central shaft sleeve on the second vertical lug, and the bearing block is in assemblyconnection with a roller frame bottom plate. The ball bearings and the bearing block as well as the bearing block and the central shaft sleeves are connected in a close fit manner; the transmission shaft and the central shaft sleeves as well as the transmission shaft and the central through hole of the driving gear are connected in a sliding fit manner; and the cross section of the transmission shaft is in a shape of regular polygon, regular triangle, square, regular pentagon or regular hexagon. According to the rotational structure, the problem that rotational driving conflicts with the axial movement of a roller frame is well solved.
Description
Technical field
The utility model belongs to pressure vessel processing technique field, be specifically related to that large diameter steel pipe is cut apart and chamfering machine on one rotational structure in axial sliding.
Background technology
Many pressure vessels are by columniform stack shell two ends welding end socket and form, and therefore many production of pressure container producer, directly purchases steel cylindrical tube from the market, oneself cut apart afterwards, bevel, and then are processed into corresponding product.Conventional method is manual line, cuts apart and bevel after pulling line with gas welding or plasma, and not only operating efficiency is low, and cuts apart end face out-of-flatness, and the groove of opening is also very nonstandard.Have in the market the steel pipe blanking beveling machine of sale, but can only accomplish that diameter is 1 meter of processing with interior steel pipe, and pipe dismounting is very inconvenient, operating efficiency is also lower.Exploitation large diameter steel pipe cut apart and the process of chamfering machine in, require on the adjustable and roller frame of roller frame longitudinal pitch active roll and driven running roller horizontal spacing adjustable, and require not affect in this linear adjustment process the output shaft rotation driving in active roll and driven voller wheel adjusting device.
Summary of the invention
The purpose of this utility model is to solve that large diameter steel pipe is cut apart and chamfering machine dependent linearity spacing adjustment process does not but affect the problem of rotary actuation, is specially one rotational structure in axial sliding.
The utility model is made up of bearing block, ball bearing, central axle sleeve, power transmission shaft and driving gear, it is characterized in that two crect ears of bearing block establish respectively ball bearing install through hole, the central axle sleeve that ball-bearing center through hole close-fitting endoporus is regular polygon, cross section is the power transmission shaft of corresponding regular polygon, order is worn and is joined the first crect ear central axle sleeve, driving gear central through hole and second crect ear central axle sleeve, bearing block and roller frame base plate assembly connection.
Described ball bearing is that close-fitting is connected with bearing block and bearing block with central axle sleeve.
Described power transmission shaft and central axle sleeve and power transmission shaft and driving gear central through hole connect for sliding accessory.
Described power transmission shaft cross section is regular polygon, itself or be equilateral triangle or for square, or be regular pentagon, or be regular hexagon.
When assembling, two ball bearings respectively with two central axle sleeves with two bearing block installing hole interference close-fittings, driving gear is between bearing block two crect ears, power transmission shaft order is worn and is joined the first central axle sleeve, driving gear central through hole and the second central axle sleeve.Power transmission shaft and central axle sleeve and power transmission shaft and driving gear central through hole connect for sliding accessory, and power transmission shaft cross section is equilateral triangle, or square, or regular pentagon, or main entrance limit shape.When use, rotatablely moving of power transmission shaft clashed by moving axially of driving gear and bearing block can not, large diameter steel pipe cut apart and chamfering machine in, the further rotation of active roll on driven roller wheel carrier base plate of driving gear, and adjust the spacing between driven running roller and active roll.
The utility model beneficial effect is: scientific structure, durable, well solved that large diameter steel pipe is cut apart and chamfering machine in rotarily actuate move axially with roller frame between mutual problem of not conflicting.

The specific embodiment
Be described as follows in conjunction with Fig. 1-Fig. 3 the utility model specific embodiment:
One is rotational structure in axial sliding, it is made up of bearing block 2, ball bearing 3, central axle sleeve 4, power transmission shaft 5 and driving gear 6, it is characterized in that 2 two crect ears of bearing block establish respectively ball bearing 3 through hole is installed, the central axle sleeve 4 that ball bearing 3 central through hole close-fitting endoporus are regular polygon, cross section is the power transmission shaft 5 of corresponding regular polygon, order is worn the central axle sleeve 4 on central axle sleeve 4, driving gear 6 central through holes and second crect ear of joining on the first crect ear, bearing block 2 and roller frame base plate 1 assembly connection.
Described ball bearing 3 and bearing block 2 and ball bearing 3 and central axle sleeve 4 are connected for close-fitting.
Described power transmission shaft 5 connects for sliding accessory with driving gear 6 central through holes with central axle sleeve 4 and power transmission shaft 5.
Described power transmission shaft 5 cross sections are regular polygon, itself or be equilateral triangle or for square, or be regular pentagon, or be regular hexagon, the present embodiment is regular hexagon.
When assembling, two ball bearings 3 are interference close-fitting with two central axle sleeves 4 and 2 two installing holes of bearing block respectively, driving gear 6 is between 2 liang of crect ears of bearing block, and power transmission shaft 5 orders are worn the central axle sleeve 4 on central axle sleeve 4, driving gear 6 central through holes and second crect ear of joining on bearing block the first crect ear.Power transmission shaft 5 connects for sliding accessory with driving gear 6 central through holes with central axle sleeve 4 and power transmission shaft 5, and power transmission shaft 5 cross sections are regular polygon, and this example is regular hexagon.When use, rotatablely moving of power transmission shaft 5 clashed by driving gear 6 and moving axially of bearing block 2 can not, large diameter steel pipe cut apart and chamfering machine in, driving gear 6 is the rotation of the active roll on driven roller wheel carrier base plate 1 further, and adjusts the spacing between driven running roller and active roll.
