Embodiment Construction

[0009] A relatively simple and practical way is to set up a total of 4 sets of crank-link mechanisms 14 on two synchronous, reverse, and parallel drive shafts (15, 16), two on each shaft, evenly and symmetrically distributed, and in the mechanism The connecting rod end of the connecting rod is spliced ​​with the bushing ring 13 on the outer cover of the large bearing ring 9 by means of the bracket 14A, and the bracket 14A is symmetrically distributed with the crank connecting rod group. Whole bearing large support ring 9 just hangs on drive shaft (15,16) by four connecting rods like this. Along with two rotating shafts (15,16) synchronously, reverse uniform rotation, whole bearing large support ring 9 is grasped and lifted, then hangs down, and its horizontal plane should guarantee not tilting.

[0010] The smooth opposite, synchronous drive of the two drive shafts (15, 16) is a critical factor. It will ensure the stability of the operation of the equipment in the whole α rot...

Abstract

The present invention relates to mechanical driving mechanism to drive the rotary body around the horizontal shaft in a rotation system, and is specifically one alpha-angle driving mechanism in furnace roof bell-free distributor. The driving mechanism includes two opposite synchronous parallel rotating shafts driven by one synchronous mechanism, four symmetrically distributed crank-connecting link mechanisms, connecting support and bearing support ring jacket. The driving mechanism forms the grabbing elevation drive to the bearing support ring, and the arced containing link hinged to the bearing support ring coverts the vertical driving force into chute-driving moment. The present invention has simple structure, smooth running, convenient operation, low cost and no radial component force.

Description

technical field [0001] The present invention is a design of a transmission mechanism, which is mainly used to provide a driving mechanism for a rotating moment to an independent rotating component around a horizontal axis in a rotating body around a vertical axis, especially for providing an α angle for a chute-type distributor on the top of a blast furnace. Rotary drive mechanism. Background technique [0002] In the object rotating around the vertical axis, there are independent parts rotating around the horizontal axis at the same time, which determines the complexity of its driving structure. Especially the driving range around the horizontal axis is the swing of 90° rotation angle, which increases the complexity of its transmission mechanism. Since P·W Company created the bellless chute distributor, the design and research of such a transmission mechanism has become a hot topic in this industry. Because this mechanism is mainly used to drive the horizontal α swing ang...
