Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-5, a bearing support seat for a roller screw comprises a base 1, mounting holes 2 are formed in two sides of the top of the base 1, a main body 3 is fixedly mounted at the top of the base 1, a thread groove 4 and a bearing groove 5 are formed in the top of the main body 3, the diameter of the bearing groove 5 is smaller than that of an inner ring of the thread groove 4, a fixing ring 6 is fixedly mounted at the bottom of the bearing groove 5, a rear through hole 7 is formed in the main body 3, a bearing 8 is sleeved inside the bearing groove 5 in a movable mode, a fixing sleeve 10 is sleeved with an internal thread of the thread groove 4, a thread 11 is formed in the outer surface of the bottom of the fixing sleeve 10, and an extrusion ring 14 is fixedly mounted inside.

Wherein, fixed sleeve 10's front fixed mounting has baffle 13, has seted up preceding through-hole 15 on the baffle 13, can have better protection to bearing 8 like this, prevents to have dust piece etc. to fall into bearing 8 in, influences the normal use of bearing.

The diameter of the rear through hole 7 is as large as that of the front through hole 15, and the rear through hole and the front through hole are both larger than the diameter of the inner ring of the bearing 8, so that the roller screw and the nut cannot be in contact with the inner wall of the fixing sleeve 10 when rotating, and the fixing sleeve 10 is prevented from loosening in the using process.

Wherein, install rubber circle 9 between extrusion circle 14 and the bearing 8, the size of rubber circle 9 is unanimous with the size of extrusion circle 14, and rubber circle 9 can play the inclosed effect of antiskid, can make bearing 8 more stable.

Wherein, fixed mounting has handle 12 on the fixed sleeve 10, and the quantity of handle 12 is four, and four handles 12 are fixed equidistance and are distributed on fixed sleeve 10, can rotate fixed sleeve 10 more easily like this, use more save trouble convenient.

The extrusion ring 14 and the fixed ring 6 are the same in size and shape, and the diameters of the inner surfaces of the extrusion ring 14 and the fixed ring 6 are smaller than the diameter of the inner surface of the outer shaft of the bearing 8, so that the outer shaft of the bearing 8 can be better fixed, and the normal rotation of the inner shaft cannot be influenced while the rotation of the outer shaft is prevented.

The working principle is as follows:

when the fixing device is used, the handle 12 is rotated to drive the fixing sleeve 10 to rotate, then the fixing sleeve 10 is separated from the thread groove 4, after the fixing sleeve 10 is screwed out, the bearing 8 is placed inside the bearing groove 5, the outer ring of the bearing 8 is arranged on the fixing ring 6, then the fixing sleeve 10 is screwed, the rubber ring 9 is pushed by the extrusion ring 14 to extrude and fix the outer ring of the bearing 8, and after the roller screw is fixed on the inner ring of the bearing 8, the base 1 is installed on the working platform through the installation hole 2.
