Embodiment
[0011] referring to accompanying drawing, wherein, identical reference character runs through several accompanying drawings corresponding to identical or similar parts, and Fig. 1 shows angular contact bearing, and generally with 10 expressions.Angular contact bearing 10 is installed in the hole 11 that is limited by gear part 12, as driving gear.Angular contact bearing 10 comprises external bearings seat ring 16 and internal bearings seat ring 18.Internal bearings seat ring 18 is characterized as the split bearing seat ring; That is, internal bearings seat ring 18 is formed by first race member 20 and second race member 22.Internal bearings seat ring 18 limiting holes 24, hole 24 sufficiently is set to receiving axes (not shown) therein.More than first roller element 26 (1 shown in Figure 1) is arranged between first race member 20 of external bearings seat ring 16 and internal bearings seat ring 18.Similarly, more than second roller element 28 (1 shown in Figure 1) is arranged between second race member 22 of external bearings seat ring 16 and internal bearings seat ring 18.In the embodiment shown, roller element 26 and 28 is spherical ball, but those skilled in the art will be appreciated that other roller element that can use in the scope of claims.More than first and second roller element 26 and 28 cooperated with external bearings seat ring 16 and internal bearings seat ring 18 provides load support and axial rigidity to teeth parts 12.
[0012] first and second many roller elements 26 and 28 operation or roll on the angled passage of two pairs of convergences.First and second race member 20 and 22 limit first and second outer passage 30 and 32 respectively, and external bearings seat ring 16 limits first and second inner channel 34 and 36.The first ball track 38 is paths of advancing in angular contact bearing 10 in each center of more than first roller element 26.Similarly, the second ball track 40 is paths of advancing in angular contact bearing 10 in each center of more than second roller element 28.First race member 20 comprises main face 42 and minor face 44, and second race member 22 comprises main face 46 and minor face 48. Main face 42 and 46 cooperations are to provide necessary gap between more than first and second roller elements 26 and 28, external bearings seat ring 16 and internal bearings seat ring 18.Thereby, must keep the tolerance of size of main face 42 and 46, with reliability and the suitable function of guaranteeing angular contact bearing 10.Preferably angular contact bearing 10 is remained in the hole 11, with the axial motion and the preload angular contact bearing 10 of limit angles contact bearing 10.In addition, external bearings seat ring 16 is undesirable with respect to the rotation of gear part 12.Below will describe in detail angular contact bearing 10 will be remained on method for optimizing and device in the hole 11 of gear part 12.
[0013] referring now to Fig. 2 and continue to show gear part 12 referring to Fig. 1, wherein the part of angular contact bearing 10 is arranged in the hole 11.Gear part 12 comprises the ring platform 47 of radial projection substantially, and ring platform 47 can be operated the axial vane surface 49 of joint external bearings seat ring 16 so that external bearings seat ring 16 is positioned in the hole 11.External bearings seat ring 16 also comprises the axial vane surface 50 that is oppositely arranged with axial vane surface 49.Gear part 12 comprises the axially extended tab portion 52 that forms by methods known in the art, and this method is for example turning, grinding, casting etc.In a preferred embodiment, axially extended tab portion 52 is extended continuously or roughly continuously around the periphery of gear part 12, thereby forms deformable lip or spine; Fig. 2 and 3 only illustrates the cross section of axially extended tab portion 52.External bearings seat ring 16 limits recess 54, and recess 54 radially extends substantially towards the hole 11 of gear part 12.In a preferred embodiment, recess 54 is tapered substantially towards the axial vane surface 50 of outside bearing race 16 away from the hole 11 of gear part 12.Recess 54 forms a plurality of projections 56, figure 2 illustrates 1.
[0014] Fig. 4 shows the stereogram of the part of gear part 12, and the part of angular contact bearing 10 is arranged in the hole 11.The figure shows (undeformed) axially extended tab portion 52 and extend continuously continuously or roughly, thereby form deformable lip or spine around the periphery of gear part 12.Recess 54 and projection 56 can seen in a plurality of zones of external bearings seat ring 16.
[0015] axially extended tab portion 52 can be axially and radial deformation, makes can being received in the recess 54, as shown in Figure 3 to small part of axially extended tab portion 52.The remaining part contact axial vane surface 50 of strained axially extended tab portion 52 does not have the zone of recess 54 or projection 56.In a preferred embodiment, axially extended tab portion 52 is rolled over by pendulum known in the art and is shaped or the distortion of rollforming technology, wherein be shaped apparatus 58 (shown in Fig. 2 dotted line) against axially extended tab portion 52 bias voltages, thereby make axially extended tab portion 52 distortion.After distortion, axially extended tab portion 52 engages with recess 54 at each place of a plurality of projections 56 of the lip circumferentially spaced that centers on external bearings seat ring 16.
[0016] referring to Fig. 3, show gear part 12, wherein the part of angular contact bearing 10 is arranged in the hole 11, and has specifically illustrated axially extended tab portion 52 and be in and be out of shape situation.Be out of shape situation, the part of axially extended tab portion 52 is received in the recess 54, and is used for the ring platform 47 bias voltage external bearings seat rings 16 against gear part 12.The remaining part of axially extended tab portion 52 contact axial vane surface 50 does not have the zone of recess 54 or projection 56, further against the ring platform 47 bias voltage external bearings seat rings 16 of gear part 12.Thus, limited the axial motion of angular contact bearing 10 in hole 11 basically.In addition, be out of shape situation, axially extended tab portion 52 copulational protuberances 56 are to limit external bearings seat ring 16 rotatablely moving with respect to gear part 12 basically.Notice that once more in a preferred embodiment, external bearings seat ring 16 and recess 54 comprise a plurality of projections 56, each projection 56 will receive the part of axially extended tab portion 52.See state before the distortion of Fig. 4 best, after axially extended tab portion 52 distortion, axial motion will by axial vane surface 50 and recess 54 the two with strained axially extended tab portion 52 between contact restriction; And radial motion will limit by the contact between projection 56 and the strained axially extended tab portion 52.By adopting recess 54 and axially extended tab portion 52 that external bearings seat ring 16 is remained in the hole 11, the parts (as snap ring) and the accurate machining that do not need to add to form groove so that snap ring is received in wherein in gear part 12; Thereby reduce the cost and the complexity of assembly.
[0017] also provides a kind of angular contact bearing 10 is remained on method in the gear part 12.Described method comprises step: form at least one axially extended tab portion 52 on described gear part 12; With at least one recess that radially extends 54 of formation in the external bearings seat ring 16 of angular contact bearing 10.Subsequently, make described at least one axially extended tab portion 52 distortion, preferably roll over and be shaped or the rollforming technology by pendulum, engaging described at least one recess that radially extends 54 of external bearings seat ring 16, thus limit described external bearings seat ring 16 with respect to described gear part 12 axially and rotatablely move.
[0018] above-mentioned discussion concentrates on angular contact bearing 10 is remained on apparatus and method in the hole that limited by gear part 12 11.Those skilled in the art will recognize that shown device and method can be used for the bearing of other type (as single-row roller bearing) is remained in the hole that limited by gear part 12 11 and remain on simultaneously in the scope of claims.Be used to implement optimal mode of the present invention though described in detail, one of ordinary skill in the art of the present invention will recognize and be used to implement various replaceable design of the present invention and embodiment in the appended claims scope.
