Looper roll bearing block preventing water from entering bearing block cavity

Abstract

The invention provides a looper roll bearing block preventing water from entering a bearing block cavity. The looper roll bearing block comprises a bearing block body. A bearing bush is fixedly arranged on the inner side wall of the bearing block body. The bearing bush is internally and rotationally connected with a shaft head of a looper roll through a bearing. The bearing bush is in clearance fit with the bearing. The end portion of the end, close to the looper roll, of the bearing is provided with a water blocking sleeve. The water blocking sleeve is arranged on the outer side of the shaft head in a sleeving manner. A second annular protrusion is arranged on the inner side wall of the bearing bush. A first annular protrusion is arranged on the outer side wall of the water blocking sleeve. The end portion of the end, close to the looper roll, of the bearing bush is fixedly provided with an annular gland. An annular gap is formed between the gland and the water blocking sleeve. A water outlet is formed in the lower portion of the gland so that the annular gap can communicate with the outside through the water outlet. An end cover is arranged at the end, away from the looper roll, of the bearing block body. An oil inlet is formed in the center of the end cover. A spacer bush is arranged between the end cover and the bearing. According to the looper roll bearing block preventing water from entering the bearing block cavity, due to the improvement on an assembly structure of the looper roll, the problem that water enters the assembly bearing block cavity can be solved.

Description

technical field [0001] The invention belongs to the field of hot-rolled narrow strip steel equipment, and in particular relates to a looper roll bearing seat which prevents water from entering the cavity of the bearing seat. Background technique [0002] In the hot-rolled narrow strip steel production line, the looper is used to adjust the tension between two adjacent rolling mills in the finishing rolling area. The looper roller assembly is an important component on the looper. The looper roll is also the component in the looper roll assembly that is in direct contact with the high-temperature rolled piece, so the looper roll is often cooled by cooling water spray. The previous looper roll assembly is relatively simple in structure, although it is easy to manufacture and install, but the waterproof effect is not ideal, and the cooling water is easy to enter the assembly bearing seat cavity and affect the lubrication of the bearing. Such as figure 1 It is the structural d...
