Abstract
The utility model discloses a novel duplex bearing. The duplex bearing comprises a bearing inner ring, a bearing outer ring, a space ring, first roll balls, second roll balls and a bearing cap, wherein the first roll balls are arranged between the bearing inner ring and the space ring; the second roll balls are arranged between the bearing outer ring and the space ring; a positioning ring is arranged on the side surface of the bearing outer ring; positioning holes are formed in the side surface of the space ring; internal threads are arranged on the inner mouth rim of the bearing outer ring; friction textures are arranged on the outer mouth rim of the bearing inner ring; external threads are arranged on the outer ring surface of the bearing cap; friction textures are arranged on the inner ring surface of the bearing cap; through holes, of which sizes are the same as those of the positioning holes and are opposite to the positioning holes, are formed in the surface of the bearing cap. According to the utility model, the bearing cap is conveniently and quickly mounted on the duplex bearing through threads; the double roll balls arranged can enable the duplex bearing to drive other shafts to rotate multi-dimensionally, so that the duplex bearing can move in the direction perpendicular to a bearing center line and can rotate around the bearing center line simultaneously, and the duplex bearing has a wide application range.
Description
Technical field
The utility model relates to a kind of novel biaxial and holds.
Background technique
Existing bearing comprises outer ring, inner ring, ball and bearing cap, ball is arranged between outer ring and inner ring, bearing cap ringwise, also between outer ring and inner ring and with ball, stand away, bearing cap, for sealing, prevent that dust from entering the space of ball rolling and affecting outer ring and inner ring effect in relative rotation, but there is the inconvenient shortcoming of installation in existing bearing cap, and existing axle is while being fixed on axle, can only realize a kind of motion mode.Can only rotate around bearing axis; And the application of bearing is now more and more extensive, will causes so existing bearing application more single, and in practical application, cause inconvenience.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of easy for installation, quick, and widely used novel biaxial holds.
For solving technique scheme, the utility model adopts following technological scheme:
A kind of novel biaxial of the present utility model holds, comprise bearing inner race, bearing outer ring, space ring, the first ball, the second ball and bearing cap, described the first ball is arranged between bearing inner race and space ring, described the second ball is arranged between bearing outer ring and space ring, described bearing outer ring side is provided with positioning ring, described space ring side is provided with positioning hole, the extended internal thread that is equipped with of described bearing outer ring internal orifice, the outer opening's edge of described bearing inner race is provided with friction line, described bearing cap outer ring surface is provided with outside thread, described bearing cap inner ring surface is provided with friction line, the surface of described bearing cap is provided with and positioning hole formed objects, and the through hole being oppositely arranged.
As preferred technological scheme, on described bearing cap, be also provided with clamping hole.
As preferred technological scheme, the first described ball is evenly distributed with six, and the second described ball is evenly distributed with eight, and described fixed hole is evenly distributed with six.
As preferred technological scheme, described bearing inner race is identical with bearing outer ring width, and the width of described bearing inner race and bearing outer ring is longer than the width of space ring.
The beneficial effect of the utility model duplex bearing is: by screw thread, bearing cap is arranged on bearing, easy for installation, quick, the two balls that arrange can make bearing drive the multi-faceted rotation of other axle, can realize simultaneously bearing along with bearing axis movement in vertical direction with and around the rotation of center line, be widely used.
