The specific embodiment
Below in conjunction with accompanying drawing and embodiment, the specific embodiment of the utility model is described in further detail.Following examples are used to explain the utility model, but are not used for limiting the scope of the utility model.
Present embodiment cover drop-head housing is cylindrical split-type structural; Cylindrical housings axially has a manhole 10; Axle center o direction along manhole 10; Housing is made up of lower house 1 and upper shell 8, and the adjacent surface of lower house 1 and upper shell 8 is the inclined-plane, and this inclined-plane becomes 57 degree angles with the axle center o of manhole 10.
As shown in Figure 1; Bearing holder (housing, cover) 2 is installed on the inclined-plane of lower house 1 through the bearing (not shown); The outer ring of its middle (center) bearing is connected with lower house 1 inclined-plane upper bearing (metal) groove close-fitting, and the hypomere of bearing holder (housing, cover) 2 is connected with the bearing inner race close-fitting, and bearing holder (housing, cover) 2 can the o ' rotation around eccentric swivel head axle center.Gear 4 and loam cake 5 are installed on the bearing holder (housing, cover) 2 successively, and through running through some bolted of three.Loam cake 5 is provided with a flange, and bearing holder (housing, cover) 2 also is provided with an inner chamber, and after loam cake 5 was placed on the bearing holder (housing, cover) 2, these loam cake 5 flanges and bearing holder (housing, cover) 2 inner chambers formed circular cavity 11 between the two.Overlapping the ring 3 that contracts places in the circular cavity 11.Cover contracts ring 3 external diameters less than circular cavity 11 internal diameters.The external diameter of said circular cavity 11, the just diameter of bearing holder (housing, cover) 2 flanges.Why making cover contract ring 3 external diameters less than circular cavity 11 internal diameters, is to make the cover ring 3 that contracts that certain free activity space arranged in circular cavity 11, could realize the casing after inflating overlapped and contract.
Because lower house 1 inclined-plane becomes 57 to spend angles with manhole axle center o, eccentric swivel head axle center o ' and manhole axle center o and become 33 to spend angles not in same plane, and these two angles are complementary angle each other.When the angle of eccentric swivel head axle center o ' and manhole axle center o is the work of cover drop-head, the contract angle of ring 3 and casing direct of travel of cover, this angle can be adjusted in the 32-34 degree according to process requirements, and optimal angle is 33 to spend.
In addition, the vertical plane top of bearing holder (housing, cover) circular hole 12 and manhole 10 o in the manhole axle center is overlapping, can pass the contract center hole of ring 3 of manhole 10 and cover to guarantee cover cover on the machine bar that contracts that contracts.
Also be provided with pilot pin 6 and locating hole 7 on the inclined-plane of lower house 1, be used for upper shell 8 inclined-planes on locating hole 7 cooperatively interact with pilot pin 6, realize two-part accurate location.
Connect external driver device for ease of gear 4; Because bearing holder (housing, cover) 2, gear 4 and loam cake 5 equal off-centre are installed in lower house 1 and the lower house 8; Therefore lower house 1 and lower house 8 all also leave the breach of a correspondence, and a part of tooth of gear 4 stretches out housing outer surface from breach.
During assembling present embodiment cover drop-head; Put bearing on the bearing groove in lower house 1 inclined-plane earlier, the outer ring of bearing is connected with the bearing groove close-fitting, the hypomere with bearing holder (housing, cover) 2 is installed in the inner ring of bearing again; Both close-fittings connect (as shown in Figure 1); The cover ring that contracts 3 is placed in bearing holder (housing, cover) 2 inner chambers, gear 4 then is installed on bearing holder (housing, cover) 2, be inserted in loam cake 5 then and with bolt with bearing holder (housing, cover) 2, gear 4 and loam cake 5 be fixed together (as shown in Figure 2).Upper shell 8 and lower house 1 are nested together, accurately locate, use bolt at last, promptly accomplish the assembling (as shown in Figure 3) of present embodiment cover drop-head upper shell 8 and the locking of lower house 1 two parts through pilot pin 6 and locating hole 7.
The end of present embodiment lower house 1 also is provided with external screw thread 9, is used to overlap drop-head and is fixedly connected with other equipment that overlap the machine that contracts.Certainly, can change external screw thread 9 into other jockeys so that be fixedly connected according to actual needs with the miscellaneous part that overlaps the machine that contracts.
During use, the cover cover that is with the inflation casing on the machine bar that contracts that contracts passes cover drop-head manhole 10 and the cover ring 3 that contracts, and the clothing wheel of dialling that cover contracts on the machine drives casing and moves forward; Gear 4 connects external driver device, drives cover in eccentric swivel head and the circular cavity ring 3 that contracts and rotates at a high speed.Ring 3 contact casing also rotate at a high speed to overlap around casing and contract because the design of the off-centre of manhole 10 and eccentric swivel head, cover are contracted.Casing surface after quilt cover contracts is shape of threads.
The above only is the preferred implementation of the utility model; Should be understood that; For those skilled in the art; Under the prerequisite that does not break away from the utility model know-why, can also make some improvement and replacement, these improvement and replacement also should be regarded as the protection domain of the utility model.
