Embodiment
Be further described below in conjunction with the embodiment of accompanying drawing the utility model.
Fig. 1 ~ Fig. 7 comprises outer ring 1, inner ring 2, steel ball 3, seal ring 4, connecting rod 5, rocking bar 6, screw 7, elastic washer 8, raceway 9, the conical surface 10, taper hole 11, center hole 12, breach 13, seal groove 14, outer lip limit 15, reducing thin groove 16, Steel Spring Plate 17, guide lip 18, sealing lip limit 19 etc.
As shown in Figure 3, the utility model is a kind of high speed swinging bearing, is applied to the articulating point between the connecting rod 5 and rocking bar 6 in the crankrocker mechanism.This high speed swinging bearing comprises outer ring 1, inner ring 2, steel ball 3 and seal ring 4.The outer ring 1 of bearing and the hole close-fitting of connecting rod 5, bearing inner race 2 links to each other with the both sides connecting plate of rocking bar 6, through lock screw 7 bearing inner race 2 and rocking bar 6 is tightened up.
As shown in Figure 4, raceway 9 both sides of bearing inner race 2 are provided with the conical surface 10, and the angle of the conical surface 10 is preferably 30 °, and this conical surface 10 contacts with the sealing lip limit 19 of seal ring 4, can guarantee the sealing effect of bearing.Center hole 12 both sides of inner ring 2 are provided with taper hole 11, and the angle of taper hole 11 is preferably 60 °.When the rocking bar 6 usefulness screws 7 of crankrocker mechanism are tightened, guarantee that bearing does not have loosening situation.7 times elastic washer 8 is housed at screw, can prevents the loosening of screw 7 in the using process.
As shown in Figure 5, raceway 9 both sides of bearing outer ring 1 are provided with seal groove 14, and it is used to supply that seal ring 4 is installed.Because bearing needs high speed swinging, therefore, raceway 9 must be through superfinish, and Ra reaches below the Ra0.05.As shown in Figure 6, on outer ring 1, also have breach 13, breach 13 is positioned on the end face of outer ring 1, is 90 ° fluting.Have breach 13 on the bearing outer ring 1, the full ball of can in bearing race 9, packing into is when outer ring 1, inner ring 2 slightly finish grind, ultra lappingout splits outer ring 1 through special tooling the steel ball 3 of packing into from splitting then after finishing at breach 13 places.
Because bearing load is bigger, has selected the large ball games design during design for use, the inner space is compact, and therefore, seal ring 4 adopts the ring flake structure, and after bearing inside was packed the long-life bearing special fat into, lubricating property was good, can improve the working life of bearing.As shown in Figure 7, the set inside of seal ring 4 has Steel Spring Plate 17, and the excircle of seal ring 4 is provided with outer lip limit 15, and outer lip limit 15 is installed in the seal groove 14 of outer ring 1.The outer peripheral surface on outer lip limit 15 has tapering, is convenient to the assembling of seal ring 4.The radially inner side on outer lip limit 15 is provided with reducing thin groove 16, and this reducing thin groove 16 helps improving the elasticity on outer lip limit 15.Be provided with sealing lip limit 19 in seal ring 4 endoporus, sealing lip limit 19 is resisted against on the conical surface 10 of inner ring 2, forms contact seal.The thickness on sealing lip limit 19 can influence sealing effect, can not be too thick, can not be too thin, and need solve through die trial.Also be provided with guide lip 18 on the plane of seal ring 4, guide lip 18 can protect grease do not flow to bearing sealed ring 4 sealing lip limit 19 on.Steel Spring Plate 17 is between guide lip 18 and outer lip limit 15.
The utility model has breach 13 on bearing outer ring 1; And seal ring 4 adopts the ring flake structure, makes it become full ball sealed structure, adopts big as far as possible ball; Nodule number is many as far as possible; Can enhance the dynamic load capacity of bearing, make bearing can carry bigger load, improve the working life of bearing.The both sides of bearing inner race 2 center holes 12 are provided with taper hole 11, can guarantee can not become flexible after the Bearing Installation.
After the utility model was used for the joint shaft bearing between crankrocker mechanism connecting rod 5 and the rocking bar 6, the problem that joint shaft bearing lost efficacy was solved at all, and the life-span of joint part can improve more than 5 times, the life-span of shaking equipment has at a high speed been had significantly promote.
