Abstract
A metal solid cage for angle contact ball bearings comprises a beam and small holes. The small holes are uniformly distributed on the beam. The right-half part of the small hole is a spherical hole. The lower part of the left-half part of the small holes is a spherical cambered surface and the upper part of the left-half part of the small holes is a half-cylindrical cambered surface hole with a titling angle equal to the contact angle of the bearing.
Description
Technical field
The invention belongs to a kind of retainer, relate generally to a kind of metal solid holding frame for angle contact ball bearing.
Background technique
The common metal solid holding frame of angular contact ball bearing mainly contains three kinds: 1, cylindrical straight pocket hole retainer as shown in Figure 1; 2, the retainer of revealing all the details of sphere as shown in Figure 2, its first half is cylindrical; 3, as shown in Figure 3, cage bar and the pocket hole oblique retainer of several angle that all tilts.Use under the situation of guiding or interior guiding outside preceding two kinds of retainers all are adapted at, promptly form certain guide clearance between the external diameter of the outer internal diameter of lasso or interior external diameter and retainer or the internal diameter.A kind of retainer in back also can adopt the rolling element guiding under the situation that sphere is revealed all the details.Three kinds of above-mentioned retainers do not form rolling element guidance mode, guidance mode inaccuracy veritably.
Summary of the invention
The purpose of this invention is to provide a kind of metal solid holding frame for angle contact ball bearing, make that it has the precision height, vibrating noise is low, running is steady, the characteristics of long service life.
Purpose of the present invention can adopt following technological scheme to realize: it is made of beam and pocket hole, the pocket hole is distributed on the beam, the right half part in pocket hole is spherical, the bottom of left-half is spherical, the top of left-half is the semicolumn cambered surface with an angle of inclination, be packing into of the accurate processing that guarantees down the spherical pocket of operation hole and steel ball, its angle of inclination should equate with the wrapping angle of bearing.The radius of arc in spherical pocket hole equates with the radius of arc in half-cylindrical pocket hole.
To have the effect of the semicolumn cambered surface at angle of inclination be to be convenient to process packing into of spherical pocket hole and steel ball to left-half in the pocket of the present invention hole, and its guiding is more accurate, and the bearing accuracy height after the assembling, vibrating noise is low, running is steady, corresponding prolongation in working life.
Description of drawings
Accompanying drawing 1 is existing cylindrical straight pocket hole retainer.
Accompanying drawing 2 is the existing sphere retainer of revealing all the details.
Accompanying drawing 3 is all the tilt oblique retainer of several angle of existing cage bar and pocket hole.
Accompanying drawing 4 is a structural representation of the present invention.
Accompanying drawing 5 is that the A of Fig. 4 is to view.
Among the figure: 1, spherical pocket hole, 2, semicolumn cambered surface pocket hole, 3, beam, 4, the pocket hole.
Embodiment
The specific embodiment of invention is described in conjunction with the accompanying drawings.
Shown in accompanying drawing 4,5: it is made of beam 3 and pocket hole 4, and pocket hole 4 is distributed on the beam 3, and it is spherical that pocket hole 4 keeps basically.The right half part in pocket hole 4 is a spherical arc, and the bottom of left-half is a spherical arc also, and both process together, is collectively referred to as spherical pocket hole 1.The top of left-half is the semicolumn cambered surface pocket hole 2 with an angle of inclination, and its tilt angle alpha equates with the wrapping angle of bearing.Among Fig. 4, putting B is the intersection point in semicolumn cambered surface pocket hole 2 and spherical pocket hole 1 (bottom of left-half), and some C is the intersection point of spherical pocket hole 1 (right half part) and retainer external diameter, and some D is the intersection point of semicolumn cambered surface pocket hole 2 and retainer external diameter.Point B and the center of the line of putting C by the pocket hole, BC is perpendicular to BD.
Add man-hour, earlier radially five equilibrium bores one than small cylindrical pocket hole, tilt alpha angular bit hemicycle cylindrical hole again, and bit drills is to putting B, and can not meet a C.Put in inside, pocket hole with ball cutter and mill the spherical pocket of system hole S Φ.The radius of arc in spherical pocket hole equates with the radius of arc in half-cylindrical pocket hole.
