(54) РОЛИКОВЫЙ СТЕНД(54) ROLLER STAND

II

Изобретение относитс к устройствам дл вращени цилиндрических изделий в нроцессе (варки, а именно, к роликовым стендам, примен емым при изготовлении цилиндрических, изделий на заводах нефт ного и химического аппаратостроени .The invention relates to devices for rotating cylindrical articles in a process (cooking, in particular, to roller stands used in the manufacture of cylindrical products at oil and chemical equipment factories.

Известен роликовый стенд, содержащий приводную и холостую роликовые опоры, установленные с возможностью перемещени в плоскости , перпендикул рной продольной оси стенда 1.A roller stand is known, which contains drive and idler roller supports mounted for movement in a plane perpendicular to the longitudinal axis of the stand 1.

Однако в данном стенде при установке издели на роликоопоры возникают перегрузки ка привод, что приводит к снижению надежности работы стенда, а перемещение опор и вращение роликов производитс индивидуальными приводами.However, in this stand, when the product is mounted on the rollers, an overload occurs as a drive, which leads to a decrease in the reliability of the stand, and the movement of the supports and the rotation of the rollers are performed by individual drives.

Ыаиболее близким по технической сущности и достигаемому результату к изобретению вл етс роликовый стенд, содержащий смонтированные на основании симметрично относительно продольной оси стенда две опоры с балансирными роликами и редукторами, а также привод с черв чным редуктором и дифференпиальный механизм, выходные валы которого соединены с соответствующими им валами реj TOpoB опор, а корпус смонтирован на выходном валу черв чного редукюра 2.The closest in technical essence and the achieved result to the invention is a roller stand containing two supports mounted on a base symmetrically relative to the longitudinal axis of the stand with balance rollers and gearboxes, as well as a drive with a worm gearbox and a differential mechanism, the output shafts of which are connected to their respective shafts rej TOpoB supports, and the housing is mounted on the output shaft of the gearbox 2.

Однако данный роликовый стенд не обеспечивает вращени на нем изделий различных диаметров при использовании единого привода дл перемещени опор и вращени роликов.However, this roller stand does not allow products with different diameters to rotate on it using a single drive for moving the supports and rotating the rollers.

Целью изобретени вл етс повыщение производительности путем обеспечени вращени на нем изделий различных диаметров при ис пользовании одного привода дл вращени роликов и дл перемещени опор.The aim of the invention is to increase productivity by ensuring that products of different diameters are rotated thereon using a single drive for rotating the rollers and for moving the supports.

Claims

The goal is achieved by the fact that a roller stand containing two supports mounted on a base symmetrically to the longitudinal axis of the stand with balance rollers and gearboxes, as well as a drive with a worm gearbox and a differential mechanism, the output shafts of which are connected to the corresponding shafts of the gearboxes of the supports, and the housing is mounted on The output shaft of the worm gearbox is equipped with an i mechanism for moving the supports in a plane perpendicular to the longitudinal axis of the stand. 3 made in the form of running nuts mounted on the supports, the lead screw mounted on the base and interacting with the running nuts, and the coupling, one of the coupling halves of which is fixed to the housing of the worm gearbox and installed with the ability to interact with the lead screw, and the other the half coupling is mounted with the possibility of longitudinal movement on the housing of the differential mechanism, while the output shafts of the differential gearbox are slotted, and on the shaft of the gearbox of each support a splined hub is mounted interacting with the splined shaft. FIG. 1 shows a roller stand; in fig. 2 - the same, top view; in fig. 3 - kinematic scheme; in fig. 4 shows a drive connecting unit with a support and rollers. The roller stand contains two movable supports 2 mounted on the base 1 symmetrically with respect to the longitudinal axis of the stand, with balancing rollers 3 mounted on the rocker arms 4 and cylindrical gears 5. On the base there is a drive 6 and a worm gearbox 7 with a differential mechanism 8. Output shafts 9 differential mechanism made shlitsevymi. The supports 2 are equipped with Costa-gear reducers 10, on the output shafts of which there are fixed sleeve shafts 11 mounted on the shafts. The stand is equipped with a mechanism for moving the supports in a plane perpendicular to the stand axis. This mechanism is implemented in the form of running nuts 12 mounted on supports 2 of the running screw 13 fixed on the base, and the coupling, the coupling half 14 which is mounted on the housing of the differential mechanism 8 with the possibility of movement, and the coupling half 15 fixed on the housing of the worm gearbox 7. On the coupling half 15 is fixed to the gear 16, and to the driving screw 13 to the gear 17, the engagement of the half coupling 14 is carried out through a system of levers 18 extended outside to the upper plane of the base. Roller stand works as follows. The product rotated on the rollers 3 of the supports 2 is rotated by turning on the drive 6 through a worm gear 7 with a differential mechanism 8, a bevel gear I 10 and a cylindrical gear 5. At the same time, the coupling 14 is disengaged from the number coupling 15 by means of a system of levers 18. Moving or spreading the rollers relative to the longitudinal axis of the stand, is carried out from the same drive 6 through the screw first gear 7 with the differential mechanism 8 and further with the semi-coupling 14 through gear 16 and 17 on the lead screw 13, on which move driving nut 12 fixed in the supports 2. The application of the roller bench allows complemented with clear its technological capabilities, simplify its construction to reduce its dimensions.
