Star-wheel outer end cap 600 is arranged in star-wheel internal end cover 500 by screw or bolt. When needs are adjustedWhen the axial distance of star-wheel 200, star-wheel outer end cap 600 is disassembled, pad 800 is adjusted in increase and decreaseThickness, without other parts of dismounting.
The said elastic component 900 of the embodiment of the present invention be mainly for spider gear shaft 100 and star-wheel internal end cover 500 itBetween a kind of axial decrement is provided. And the position that star-wheel internal end cover 500 contacts with elastic component 900 arrangesHave annular projection, one end and the annular projection of elastic component 900 offset, the other end of elastic component 900 and bearing400 outer ring offsets.
Or star-wheel internal end cover 500 arranges jump ring with the position that elastic component 900 contacts, one of elastic component 900End offsets with jump ring, and the outer ring of the other end of elastic component 900 and bearing 400 offsets.
In the time that needs are vertically gone up mobile spider gear shaft 100, star-wheel outer end cap 600 is disassembled to rootIncrease the thickness of adjusting pad 800 according to actual measurement, then star-wheel outer end cap 600 is installed, in installation processIn, because the thickness of adjusting pad 800 increases, adjust pad 800 and will on vertical direction, push bearing400 outer ring, bearing 400 outer ring extruding elastic components 900 simultaneously, compression elastic piece 900, thus realize starThe axial movement upwards of wheel shaft 100, the axial movement upwards of spider gear shaft 100 has realized the axle of star-wheel 200To movement upwards.
In the time that needs vertically descend mobile spider gear shaft 100, star-wheel outer end cap 600 is disassembled to rootReduce the thickness of adjusting pad 800 according to actual measurement, then star-wheel outer end cap 600 is installed, in installation processIn, because the thickness of adjusting pad 800 reduces, elastic component 900 will push bearing 400 under vertical directionOuter ring, pads 800 are adjusted in simultaneously bearing 400 outer rings extruding, thus realize spider gear shaft 100 axially downwardsMovement, the axial downward movement of spider gear shaft 100 has realized the axial downward movement of star-wheel 200.
The said elastic component 900 of the present invention has certain deformation quantity and recovers the ability of deformation, Ke YiweiSpring, spring washer etc., preferably adopt waved spring packing ring in the embodiment of the present invention.
Embodiment of the present invention middle (center) bearing 400 is angular contact ball bearing, waits the bearing 400 that meets design needs.The quantity of bearing 400 is one, two or is more as required. In more excellent scheme, bearing 400Quantity be two and be set up in parallel on spider gear shaft 100.
To the above-mentioned explanation of the disclosed embodiments, professional and technical personnel in the field can be realized or useThe present invention. To be aobvious and easy for those skilled in the art to the multiple amendment of these embodimentSee, General Principle as defined herein can be in the situation that not departing from the spirit or scope of the present invention,Realize in other embodiments. Therefore, the present invention will can not be restricted to these embodiment shown in this article,But to meet the widest scope consistent with principle disclosed herein and features of novelty.
