Abstract
The utility model discloses a liquid crystal display (LCD) panel guide wheel bearing, comprising an outer ring, an inner ring, steel balls and a retainer; the outer ring and the inner ring are provided with roller paths matched with the retainer; the steel balls are arranged on the retainer sleeved in the roller paths between the outer ring and the inner ring; a bulge with a semicircular or arch section is arranged at the outer circle of the outer ring. According to the LCD panel guide wheel bearing, the contact area between an LCD panel and the outer ring of the guide wheel bearing is effectively reduced and abrasion is reduced.
Description
Technical field
The utility model relates to a kind of bearing, is specifically related to a kind of TFT LCD guide wheel bearing.
Background technique
Kinds of bearings is various, comprises deflector roll bearing, guide wheel bearing, thrust-bearing, tapered roller bearing, deep groove ball bearing, angular contact ball bearing, roller bearing, needle bearing etc., applies that very scope is wide.In TFT LCD working process, when TFT LCD is carried, need use guide wheel bearing, existing basic model guide wheel bearing generally comprises outer ring, inner ring, steel ball and retainer, because TFT LCD directly contacts with guide wheel shaft bearing outer-ring, at course of conveying, produce larger friction, affect TFT LCD quality.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of TFT LCD guide wheel bearing, can effectively reduce the area of contact of TFT LCD and guide wheel shaft bearing outer-ring, reduces friction.
The technological scheme that the utility model technical solution problem adopts is: a kind of TFT LCD guide wheel bearing, comprise outer ring, inner ring, steel ball and retainer, described outer ring is provided with and mates the raceway that is set with retainer with inner ring, described steel ball is placed on retainer, described retainer is sleeved in the raceway between inner ring and outer ring, it is characterized in that: on the cylindrical of described outer ring, be provided with cross section for semicircle or arc projection.
The beneficial effects of the utility model are: on the cylindrical of outer ring, be provided with cross section for semicircle or arc projection, can effectively reduce the area of contact of TFT LCD and guide wheel shaft bearing outer-ring, reduce friction.
Accompanying drawing explanation
Fig. 1 is that schematic diagram is looked on the utility model embodiment's a left side.
Fig. 2 is that A in the utility model embodiment Fig. 1 is to schematic diagram.
Fig. 3 is the utility model embodiment's stereogram.
Below in conjunction with accompanying drawing, the utility model is described further.
