Abstract

The utility model relates to a one-way combined bearing with key grooves. The bearing comprises an inner and an outer rings between which a cage is placed. The utility model is characterized in that the cage is composed of a ball cage and a roller cage. Balls and rollers are uniformly and respectively arranged in the ball cage and the roller cage along the circumferential direction. The inner wall of the inner ring or / and the outer wall of the outer ring is /are provided with the key grooves. The bearing has the advantages of convenience installation and manufacture, etc.

Description

The unilateral bearing of band keyway
The utility model relates to a kind of unidirectional combination bearing that has keyway.
Existing bearing has keyway on the outer ring within it mostly, during installation, utilize interference fit and axle or mutual fastening connection of hole usually, thereby dismounting is cumbersome, existing bearing mostly is the common deep groove ball bearing or the unidirectional clamping stopper bearing of function singleness in addition, and its defective is that driving torque is little.For this reason, the applicant once disclosed a kind of bearing with sealing function that deep groove ball bearing and unidirectional clamping stopper bearing are combined in the ZL96223898.8 patent, but this bearing must be made the outer ring upper and lower two-part, and the structure more complicated is made difficulty is installed comparatively speaking.
The purpose of this utility model is a kind of unilateral bearing of making band keyway easy for installation of design.
Its main technical schemes comprises bearing inner race and outer ring, between inside and outside circle, place retainer, this retainer is made of ball retainer and roller rolling retainer, along the circumferential direction places ball and roller in two retainers respectively equably, at the inwall of inner ring or/and the outer wall of outer ring has keyway; Internal surface in the outer ring has when outer ring (or inner ring) corresponding to the position that roller is installed to be fixed, when inner ring (or outer ring) can move, play the concave curve of restriction inner ring (or outer ring) moving direction effect, the arcuate segment of one end of each concave curve for allowing roller move betwixt, the other end is and the spacing of the inner ring straightway less than the diameter of roller, the centre is smooth changeover portion, place respectively between corresponding to the roller of the arcuate segment of each concave curve and cylindricality retainer can make roller under the static state near the spring of the straightway of concave curve: the breach of installation ball retainer or roller rolling retainer is arranged respectively on the internal surface in the outer surface of the inner ring at bearing two ends and outer ring, used spring be "
Figure Y9822638800031
Shape spring, the keyway on the inside and outside circle are semicircular keyway; In roller rolling retainer, along the circumferential direction to place equably in each unit of roller, an end of close roller is an arc surface, the other end is for ease of placing the step of spring.
The utility model has the advantages that since between an inner ring and outer ring ball of placement and retainer thereof and roller and retainer thereof, compare with original structure, fairly simple, be convenient to install and manufacturing, simultaneously, after original deep groove ball bearing and the combination of unidirectional clamping stopper bearing, increased driving torque, concentricity is higher, action is accurate, essentially no retardation angle, and this composite structure friction torque when rotated is little, noise is low, and self-locking property is good; Secondly, after being provided with keyway on the inside and outside circle of bearing, when cooperating with axle or hole, need not strict drive fit, be convenient to installation: the 3rd, used roller rolling retainer and corresponding inside and outside coil structures make this product have special function.
Fig. 1 is a structural drawing of the present utility model.
Fig. 2 is the left view of Fig. 1.
Fig. 3 is the A-A enlarged view of Fig. 1.Fig. 4 is for removing B behind the outer ring among Fig. 3 to figure.
As shown in the figure: the outer surface of the inner ring 4 on the left of bearing and the internal surface of outer ring 1 are provided for installing the breach 15,16 of ball retainer 3 respectively, ball retainer 3 and ball 2 are positioned between the inside and outside circle of this side, internal surface in the outer surface of the inner ring 4 on bearing right side and outer ring 1 is provided for installing the breach 18,17 of roller rolling retainer 8 respectively, and roller rolling retainer 8 and roller 6 are positioned between the inside and outside circle of this side.At the internal surface of bearing inner race 4 and the outer surface of outer ring 1 semicircular interior spline 5 and outside keyway 9 are set respectively, ball 2 along the circumferential direction is placed on respectively in ball retainer 3 and the roller rolling retainer 8 equably with roller 6.
In roller rolling retainer 8, place in each unit of roller 6, end near roller 6 is an arc surface 20, the other end is a step 9, in the outer ring 1 internal surface corresponding to the position that roller 6 is installed have when outer ring 1 fixing, when inner ring 4 can move, play the concave curve of restriction inner ring moving direction effect, the arcuate segment 11 of one end of each concave curve for allowing roller 6 move betwixt, the other end is and the spacing of inner ring 4 straightway 13 less than the diameter of roller 6, the centre is smooth changeover portion 12, between step 9, place corresponding to the roller 6 of the arcuate segment 11 of each concave curve and roller rolling retainer 8 can make roller 6 under static state near the straightway 13 of concave curve "
