Abstract
The utility model relates to a vertical combined dual needle roller bearing with a seat which supplies a gap of the prior art that two rotary motions are changed into a final beeline motion. The utility model is characterized in that a bottom plate 12 with a through hole is connected with a seat 11. A large needle roller 2 is arranged between a large external ring 10 and a large internal ring connected with the seat 11. A small needle roller 8 is arranged between a small external ring 9 and a small shaft 6. The two sets of needle rollers are mutually vertical. A tightening screw 1 passes through a profiled cover plate 3 and is then connected with the seat 11. Two ends of the small external ring 9 are provided with a retaining piece 7. The prior art is not provided with a bearing with the structure. As the function of the bearing, the two initial rotary motions are changed into the final beeline motion. The utility model can be used for transmission mediums.
Description
The utility model relates to a kind of as rotating the bearing that medium is used, particularly a kind of two needle bearings of Vertical direction combination of usheing to seat.
Bearing of the prior art, its structure is to be fixed with the retainer that steel ball is housed on it between inside and outside circle nothing more than.Its deficiency is owing to do not break through above-mentioned traditional design thought, does not still have so rotatablely move to become in the last straight-line Vertical direction combination pair needle bearing prior aries of usheing to seat by two kinds.
The purpose of this utility model is to solve above-mentioned deficiency of the prior art, fills up its blank, and a kind of two needle bearings of Vertical direction combination of usheing to seat are provided.
Technical solution of the present utility model is: the base plate 12 that has through hole on it links to each other with seat 11.Big outer ring 10 with big inner ring 5 that seat 11 links to each other between be big needle roller 2.Between little outer ring 9 and the little axle 6 is little needle roller 8.This two covers needle bearing is vertical mutually.Fastening screw 1 passes special-shaped cover plate 3 and links to each other with seat 11.The two ends of little outer ring 9 are provided with catch 7.
The advantage that the utility model is had compared to existing technology is: do not have the bearing of this structure in the prior art, because the effect of this bearing, feasible two kinds of beginning rotatablely move and become last straight line motion.
This accompanying drawing is that overall structure master of the present utility model looks cross-sectional schematic.
The utility model is described in further detail below in conjunction with accompanying drawing: the base plate 12 that has through hole on it links to each other with seat 11.Big outer ring 10 with big inner ring 5 that seat 11 links to each other between be big needle roller 2.Between little outer ring 9 and the little axle 6 is little needle roller 8.This two covers needle bearing is orthogonal.Fastening screw 1 passes special-shaped cover plate 3 and links to each other with seat 11.The two ends of little outer ring 9 are provided with catch 7, to stop little needle roller axial float.The rib of big outer ring 10 and big inner ring 5 is provided with " O " RunddichtringO, and is excessive to prevent that dust from entering with grease.Hole on the base plate links to each other with frame.During work, little needle bearing is done the rotation of directions X around little axle; Big needle bearing is done the rotation of Z direction around the big inner ring that is connected on the axle, makes workpiece along Y direction moving linearly.Can be provided as and rotate medium usefulness.
