Summary of the invention
The purpose of this utility model is in order to overcome the deficiencies in the prior art, a kind of breast roll device that is used for collective's transmission of heavy and medium plate mill gateway to be provided, its transmission accuracy height, and the driving parts life-span is long, reduces the weakening to frame strength to greatest extent.
The technical scheme that realizes above-mentioned purpose is: a kind of breast roll device that is used for collective's transmission of heavy and medium plate mill gateway, comprise the frame that is positioned at both sides, milling train entry and exit, be positioned at outer and two drive motors that be arranged in parallel of frame one side, four be separately fixed at gear-box on the machine frame at two sides inner surface of entry and exit, be connected across on the machine frame at two sides of entry and exit one initiatively breast roll and two driven breast rolls respectively; On inherent one first center line of described gear-box a driving gear and two driven gears are installed, parallel and be lower than on second center line of first center line two transition gears are installed at another; Described driving gear and two driven gears are connected with a joggle by described transition gear respectively; Described drive motors is connected on the driving gear of frame one side by connecting axle; The two ends of described active breast roll are connected on the driving gear of frame both sides, the two ends of described driven breast roll are connected on the driven gear of frame both sides, described gear-box is fixed in the mode of protruding the frame outer end edges, and driving gear is installed in outermost end near gear-box so that described connecting axle outside frame be arranged on described gear-box in driving gear be connected.
The breast roll device of the above-mentioned collective's transmission that is used for the heavy and medium plate mill gateway, wherein, described gear-box is a solid forging.
The breast roll device of the above-mentioned collective's transmission that is used for the heavy and medium plate mill gateway, wherein, described drive motors is to be connected with connecting axle with one speed reducer by a shaft joint successively.
The breast roll device of the above-mentioned collective's transmission that is used for the heavy and medium plate mill gateway, wherein, described connecting axle is a universal-joint spindle.
The breast roll device of the above-mentioned collective's transmission that is used for the heavy and medium plate mill gateway, wherein, described driving gear and driven gear are roller gear.
Owing to adopted the technical scheme of the breast roll device of the collective's transmission that is used for the heavy and medium plate mill gateway of the present utility model, promptly need not on frame, to bore a hole, reduce weakening to greatest extent to frame strength, the transmission accuracy height, the driving parts life-span is long, and number of motors is few, and investment cost is lower, power consumption is less, meets energy-saving and cost-reducing national conditions needs.Gear-box is whole forging structure in addition, and processing technology is good, and has improved self rigidity and impact resistance.
