Abstract
The invention discloses a double-worm turntable bearing swing driving pair, which comprises a double-worm drive device, and is characterized in that a double-row thrust angular contact cylindrical roller turntable bearing is arranged in the double-worm drive device, and worms of the double-worm drive device are arranged on an outer circle of an inner ring (4) of the thrust angular contact cylindrical roller turntable bearing. By the aid of the scheme of arranging double-row roller paths and double-row cylindrical rollers, a rolling body linearly contacts with the roller paths. The roller paths have a certain inclined angle, so that load bearing capacity is increased, and the bearing is capable of bearing axial and radial load and large overturning moment. As outer teeth are arranged in the middle of the height of the outer circle of the inner ring, worm gears can be mounted on the outer circle of the inner ring. Compared with an existing double-row four-point contact ball turntable bearing with outer teeth, the double-row thrust angular contact cylindrical roller turntable bearing has the advantages that load bearing capacity can be greatly improved under the same space condition, and rigidity and overturning moment bearing capacity are improved. The double-worm turntable bearing swing driving pair has the advantages of simple structure, space saving, convenience in use and cost reduction.
Description
Technical field
The invention belongs to the mechanical transmissioning technology field, what relate generally to is that a kind of twin worm contacts cylindrical roller turntable bearing combination revolution driving auxiliary with push angle.The fields such as heavy duty crane, portal crane, slingcart adaptable across the mine.
Technical background
Twin worm contacts cylindrical roller turntable bearing combination revolution driving auxiliary with push angle be to satisfy big speed ratio, big powerdriven device, is two between centers transmitting movement and the power staggered in the space.Be mainly used in transmitting movement and the powered device, particularly on the revolution device for hoisting of mine heavy duty equipment, portal crane.Existing twin worm worm drive pair mainly contains two kinds: a kind of ball bearing, housing, left end cap, worm screw or worm shaft, worm screw positioning bearing, right end cap, loam cake and power source of joining by a worm gear, with worm gear (also have do not dispose the power source user dispose power source voluntarily) formed; Another kind is that worm gear, housing, left end cap, worm screw or worm shaft, worm screw positioning bearing, right end cap, loam cake and power source (also have do not dispose the power source user dispose power source voluntarily) are formed by the four point touching ball slewing bearing of a band external toothing.These two kinds of twin worm worm gear pairs are because turbine is joined ball bearing or 4 ball slewing bearings all are single-row ball-bearings; Rolling element and raceway all are to contact; Ability and the intensity of itself bearing load is restricted under the same spatial condition, can not satisfy same spatial position mine heavy duty crane and portal crane heavy load, high tenacity, the requirement of tilting moment greatly.
Summary of the invention
The object of the invention produces thus; Propose a kind of twin worm and contact cylindrical roller turntable bearing combination revolution driving auxiliary with push angle; Effectively improve load bearing capacity and intensity, increase the tilting moment ability to bear, under same spatial condition, can satisfy the requirement of heavy load, big tilting moment.
The present invention realizes that the technological scheme that above-mentioned purpose is taked is: in the twin worm transmission device, be provided with biserial push angle contact cylindrical roller turntable bearing, the worm gear of said twin worm transmission device is arranged on the cylindrical of said push angle contact cylindrical roller turntable bearing inner ring.
Said biserial push angle contact cylindrical roller turntable bearing comprises inner ring, two raceways, first line column roller, secondary series cylindrical roller, first outer ring and second outer rings; Cylindrical middle part at said inner ring is evenly equipped with external tooth; Be positioned on the inner ring cylindrical at this upper and lower position of external tooth and also be symmetrically arranged with raceway; This raceway is a leaning structure, wherein in the raceway of bottom, is provided with first line column roller, in the raceway on top, is provided with the secondary series cylindrical roller; First line column roller compresses the location by first outer ring, and the secondary series cylindrical roller compresses the location by second outer ring.
The inner ring and the worm gear of described biserial push angle contact cylindrical roller turntable bearing can be structure as a whole, and also can be the branch body structure.
Described biserial push angle contact cylindrical roller turntable bearing is installed on the housing bottom surface of said twin worm transmission device.
Second outer ring of said biserial push angle contact cylindrical roller turntable bearing is fixed on the housing upper end of said twin worm transmission device.
First outer ring of said biserial push angle contact cylindrical roller turntable bearing is fixed on the housing lower end of said twin worm transmission device.
The present invention solves the problem that existing twin worm worm drive pair can not satisfy heavy load, high tenacity, big tilting moment through biserial push angle contact cylindrical roller turntable bearing is set; Through the scheme of biserial raceway and double-row cylindrical roller is set, reach the target of rolling element and Race Line Contact.And raceway has certain angle of inclination, has increased load-carrying ability thus, make bearing can reach to and radial load, and big tilting moment.Because external tooth is arranged on the middle part of inner ring external diameter; Like this; Worm gear just can be installed in above the inner ring external diameter, compares with existing band external tooth biserial four point touching ball slewing bearing, under same spatial condition, can increase substantially load bearing capacity; Increase rigidity and tilting moment ability to bear, satisfy the requirement of field heavy loads such as mine heavy duty crane, portal crane, slingcart, big tilting moment.Have simple in structurely, save the space, easy to use, the characteristics that reduce cost.
