Double-screw-rod roller side pressure adjusting device

Abstract

The invention provides a double-screw-rod roller side pressure adjusting device, and the adjusting device is of a bilateral symmetry structure. A motor is in a direct connection with a reducer, and the reducer is installed on a supporting frame; a gear assembly comprises a small gear, a middle gear and an outer gear; the first end of the small gear is fixed to an output shaft of the reducer, and an assisting bearing is fixed to the second end of the small gear; a supporting seat assembly comprises the supporting frame, an inner supporting seat and an outer supporting seat; the middle gear is rotated by the inner supporting seat through a bearing, and the outer gear is rotated by the outer supporting seat through a bearing; the outer gear drives an outer screw rod through a bearing cover and a key, and the outer screw rod slides axially in an inner hole of the bearing cover; a nut assembly comprises an outer nut and a locknut; the outer screw rod and the outer nut form a thread pair; an inner thread of the outer screw rod and an inner screw rod form a thread pair; and the locknut and the inner screw rod form a thread pair. According to the double-screw-rod roller side pressure adjusting device, overall roller integrated adjusting is achieved by utilizing the outer screw rod in a linkage electric adjusting mode, and roller micro-adjusting is achieved by utilizing the inner screw rod in an individual adjustment mode.

Description

technical field [0001] The invention relates to the field of steel ball or steel forging skew rolling mills, in particular to a double-screw roll side pressure adjustment device. Background technique [0002] In steel ball rolling, the roll side pressure adjustment device is used to adjust the roll distance. The requirements of the steel ball skew rolling mill for the adjustment of the roll distance: 1. The overall adjustment of the entrance and exit ends of the roll, including the overall advance or retreat of the roll; 2. Independent fine-tuning at the entrance of the roll, including advancing or retreating at the entrance of the roll; 3. Individual fine-tuning at the exit of the roll, including advancing or retreating at the exit of the roll. [0003] The currently applied roll side pressure adjustment method, because the two ends of the single screw rod (the inlet end and the outlet end of the roll) are separately adjusted, the overall linkage adjustment of the roll cann...

Problems solved by technology

[0003] The currently applied roll side pressure adjustment method, because the two ends of the single screw rod (the inlet end and the outlet end of the roll) are separately adjusted, the overall linkage adjustment of the roll cannot be realized, and the roll distance needs to be frequently measured during the adjustment process, especially for small sizes. Unit, the adjustment is time-consuming, difficult, labor-intensive and inefficient
