As an improvement of the utility model, the axial hole aperture of the bearing fixing seat and the bearing cap is 15 mm.

As an improvement of the round flange lead screw supporting seat of the utility model, the other end of the spacing ring is screwed with a locking nut.

As the utility model discloses a round flange lead screw supporting seat's improvement, the one end of bearing fixing base is equipped with connection platform, the interval is equipped with a plurality of screws on the connection platform.

As the utility model discloses a round flange lead screw supporting seat's improvement, the bearing cap corresponds the position of screw all is equipped with the through-hole, the through-hole wear to establish the screw with the screw is connected.

As an improvement of the utility model, the total length of the bearing fixing seat and the bearing cover is 46 mm.

Compared with the prior art, the utility model has the advantages that: the utility model discloses set up the bearing in the bearing fixing base, it is fixed through the bearing cap contact to set up the spacer ring in the bearing cap, be equipped with the oil blanket between the axial hole inside wall of spacer ring and bearing cap, can guarantee the more smooth and easy operation of bearing. The support can adapt to different installation modes. A group of angular contact bearings are installed in the DF mode, and effective radial stress and axial stress can be provided for the ball screw. The clearance between the inner ring and the outer ring of the bearing and the ball is effectively reduced in a preloading mode, and the high-precision requirement of the rotation of the lead screw is met.

Drawings

The invention and its advantageous technical effects are described in further detail below with reference to the accompanying drawings and embodiments, in which:

fig. 1 is a sectional view of the present invention.

Fig. 2 is a side view of the present invention.

Reference symbol names: 1. bearing fixing seat 2, bearing cap 3, axial hole 4, bearing mounting groove 5, bearing 6, annular step 7, spacer ring 8, oil blanket 9, lock nut 10, connection platform 11, screw 12, through-hole.

Detailed Description

The invention will be further described below with reference to the drawings and specific examples, but the embodiments of the invention are not limited thereto.

As shown in fig. 1 and fig. 2, a round flange lead screw supporting seat, including bearing fixing base 1 and bearing cap 2 that the external diameter is 40mm, bearing cap 2 lid is in the great one end of bearing fixing base 1 diameter, the middle part of bearing fixing base 1 and bearing cap 2 all is equipped with axial hole 3, be equipped with bearing mounting groove 4 on the 3 lateral walls of axial hole of bearing fixing base 1, be equipped with at least one bearing 5 in the bearing mounting groove 4, a side that bearing cap 2 corresponds bearing fixing base 1 is equipped with annular step 6, annular step 6 inlays at the 3 opening edges of axial hole of bearing fixing base 1, install a spacer ring 7 in the axial hole 3 of bearing cap 2, be equipped with oil blanket 8 between the 3 inside walls of axial hole of spacer ring 7 and bearing cap 2. The spacer ring 7 can isolate friction between the screw and the bearing cap 2, preventing the bearing cap 2 from being damaged. And the oil seal 8 can prevent the bearing 5 in the bearing fixing seat 1 from overflowing lubricating oil when rotating, and the smooth rotation of the bearing is ensured. Before the bearing is installed, lubricating grease is coated on the bearing for lubrication.

Preferably, the hole diameters of the axial holes of the bearing fixing seat 1 and the bearing cover 2 are both 15 mm.

Preferably, a locking nut 9 is screwed to the other end of the spacer ring 7.

Preferably, one end of the bearing fixing seat 1 is provided with a connecting platform 10, and the connecting platform 10 is provided with a plurality of screw holes 11 at intervals.

Preferably, the bearing cover 2 is provided with a through hole 12 at a position corresponding to the screw hole 11, and the through hole 12 is connected with the screw hole 11 by a screw.

Preferably, the total length of the bearing holder 1 and the bearing cap 2 is 46 mm.

The utility model discloses set up the bearing 5 bearing in the bearing fixing base, fixed through the 2 contacts of bearing cap to set up spacer ring 7 in the bearing cap, be equipped with oil blanket 8 between 3 inside walls of axial hole of spacer ring 7 and bearing cap 2. The support can adapt to different installation modes. A group of angular contact bearings are installed in the DF mode, and effective radial stress and axial stress can be provided for the ball screw. The clearance between the inner ring and the outer ring of the bearing and the ball is effectively reduced in a preloading mode, and the high-precision requirement of the rotation of the lead screw is met.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and structures of the invention, the scope of which is defined in the appended claims and their equivalents.
