Embodiment Construction

[0018] The invention provides a driving device for idler rollers, comprising: a deceleration motor connected in sequence, a universal coupling and at least two transmission shafts, the transmission shafts are connected by couplings, and each transmission shaft is sleeved with two The bearing seat and two transmission sprockets, the transmission sprocket drives the driven sprocket on the idler roller through the chain. Optionally, the free end of the transmission shaft farthest from the reduction motor is provided with a gland, and the gland fixes a transmission sprocket of the transmission shaft.

[0019] Such as figure 1 and 2 As shown, the present invention will be described in detail by taking a transmission device with three transmission shafts as an example. The idler transmission device includes: a geared motor 100, a universal joint 200, a first transmission shaft 310, a first transmission shaft 410, a second transmission shaft 320, a second transmission shaft 420 and...

Abstract

The invention provides a carrier roller drive device. The carrier roller drive device comprises a slowdown motor, a universal coupling and at least two drive shafts which are sequentially connected, wherein the drive shafts are connected through the coupling, each drive shaft is sleeved with two bearing pedestals and two drive sprockets, and each drive sprocket drives a driven sprocket on a carrier roller through a chain. The carrier roller drive device provided by the invention is reliable in structure and simple and easy to operate, and the simultaneous rotation and stopping of all carrier rollers in operation under the driving a slowdown motor is realized, thereby reducing the occurrence of a situation that the surfaces of hollow billets are scratched because carrier rollers are not synchronized in the prior art. Because the slowdown motor is arranged away from a high-temperature billet, the damages caused by high-temperature burning are avoided, thereby reducing the number of required spare parts. Therefore, the production cost can be reduced while the production efficiency can be improved.

Description

technical field [0001] The invention relates to the production field of seamless steel pipes, in particular to an idler transmission device. Background technique [0002] In the production process of the existing seamless steel pipe, the hollow capillary tube is pierced by the piercer and enters the anti-oxidant spraying station (rotating roller). The capillary tube with a temperature as high as 1150 degrees Celsius needs to stay on the rotating roller for about 6 seconds. The rotating idler is independently driven by the geared motor installed below. The geared motor is easily damaged due to the frequent close-range high-temperature roasting of the capillary. It needs to be stopped frequently to replace the geared motor, which delays production time and requires more spare parts to meet unexpected needs. . And because each idler is driven by different reduction motors, it is easy to cause each idler to run asynchronously and scratch the surface of the capillary. Contents...
