Description
Technical field
Mechanical equipment technical field is the utility model is related to, more particularly, to a kind of double wire roller pivoting support.
Background technology
Existing pivoting support material structural alloy steel, overall weight, rolling element and raceway contact area are big, frictional force
Greatly, speed-raising is slow, and volume is also very big, and the pivoting support installing space that some specific application scenarios use is narrow and small, it is desirable to load
Less, light weight and raise speed fast and wire roller pivoting support is exactly in light weight, simple in construction, installing space very little, maintenance
Change conveniently and cost is cheap, while there is the basic function of pivoting support again, can bear axially and radially to load, can also bear
Certain tilting moment, so, wire roller bearing can substitute common light duty revolution branch completely under certain use occasion
Hold, reach the inaccessiable using effect of common pivoting support.
The content of the invention
In order to overcome the shortcomings of in background technology, the utility model discloses a kind of light weight, the fast, flexible rotation that raises speed to put down
Surely and service life length double wire roller pivoting support.
In order to realize the goal of the invention, the utility model adopts the following technical scheme that：A kind of double wire roller revolution
Supporting, including inner ring and outer ring, the inner ring include half upper inner ring and half time inner ring, partly upper to pass through between inner ring and half time inner ring
Connecting bolt connects；Stretch out on the outside of the upper part of the half upper inner ring, its lower surface forms and promotes mainly torque raceway space
Upper raceway；Extended internally in the middle part of the outer ring, its upper surface forms the lower raceway for promoting mainly torque raceway space, upper raceway and lower rolling
Formed between road and promote mainly torque raceway space with circular arc chamfering, promoted mainly to set torque raceway space in and go up steel ball, it is described on
Be respectively arranged with four upper steel wires between steel ball and four chamfering inwalls for promoting mainly torque raceway space, and inside and outside up and down
A holder is also respectively provided between two upper steel wires；Stretch out on the outside of the lower part of half time inner ring, thereon
End face forms the lower raceway for promoting mainly torque raceway space；Extended internally in the middle part of the outer ring lower surface of part forms propulsive thrust square
The upper raceway in raceway space, the propulsive thrust square raceway space with circular arc chamfering, propulsive thrust are formed between upper raceway and lower raceway
Lower steel ball is set in square raceway space, it is parallel respectively between the lower steel ball and four chamfering inwalls in propulsive thrust square raceway space
Be provided with four lower steel wires, and inside and outside two lower steel wires up and down between be also respectively provided with a lower retainer.
For further improved technology scheme, position inside and outside upper steel ball described in the utility model, half upper inner ring to
Extended internally in the middle part of the lower surface and outer ring of outer extensions point part upper surface between be provided with retainer passage, holder
It is arranged in retainer passage.
For further improved technology scheme, position inside and outside upper steel ball described in the utility model, half upper inner ring to
Extended internally in the middle part of the lower surface and outer ring of outer extensions point part upper surface between be provided with retainer passage, lower retainer
It is arranged in retainer passage.
By adopting the above-described technical solution, the utility model has the advantages that：It is described in the utility model double
Wire roller pivoting support, two row's raceways are provided between inner ring and outer ring, two row's raceways design into circular arc type, main thrust raceway
Four steel wires are respectively equipped with propulsive thrust raceway, have row's steel ball among four rolled thread, steel ball moves in a circle along steel wire.
In addition, two row's steel balls are used in parallel, rolling element moves along central axial when this pivoting support rotates, steel ball and steel
Silk contact, contact area is small, and frictional force is small, and in the case where bearing axial load and tipping load, bearing can be more easily
Rotation, and the rotating speed of equipment needs is brought up to quickly.
For this structure in the case where carrying is certain, the space to be taken is small, and precision is high, and rotation is steady, end face run-out
It is small.
Maintenance cost is low, convenience easy to maintenance, if galloping occurs in bearing, axially and radially clearance increase causes jump
It is dynamic big, it can not meet the requirement of equipment precision, without the bearing more renewed, it is only necessary to change steel wire and rolling element component.
The utility model reduces the installing space of bearing, and steel ball only contacts with steel wire, reduces the friction to contact with each other
Loss, improves rotary speed and smooth rotation, the whole efficiency of pivoting support is improved 50%~70%.
