Abstract
The utility model relates to a turntable bearing which consists of an upper single raceway axis ring, a lower single raceway axis ring and a double raceway seat ring. An upper retainer is arranged at the lower end of the single raceway axis ring, a lower retainer is arranged at the lower end of the double raceway seat ring, and both of the upper retainer and the lower retainer are matched with steel balls. In the turntable bearing, two single raceway axis ring with different sizes and one double raceway seat ring are arranged, the carrying capacity of the turntable bearing is high, the limit speed is higher, the noise is low, the reliability of equipment is high, the structure is simple, the installation and disassembly are convenient, and the needs of the production of the people can be met.
Description
Technical field
The utility model relates to a kind of bearing, particularly a kind of Rotary table for drilling machine bearing.
Background technique
Existing Rotary table for drilling machine main bearing loading capability is low, limit speed is lower, and noise is big, the poor reliability of equipment, complex structure, installing/dismounting inconvenience, and present bearing can't satisfy the needs that people produce.
The model utility content
Order of the present utility model is to overcome above-mentioned the deficiencies in the prior art, provide a kind of simple in structure, bearing capacity is high, noise is low, the turntable bearing of easy installation and removal.
The technological scheme that the utility model adopted is such: a kind of turntable bearing, by two single raceway blowout patches and two raceway seat ring are formed up and down, described single raceway blowout patche lower end is provided with holder, two raceway seat rings lower end is provided with down retainer, all cooperate to be provided with steel ball the described diameter difference of two single raceway blowout patches up and down on described holder and the following retainer.
Described pair of raceway seat ring is provided with the installation tapped hole.
By adopting the aforementioned techniques scheme, the beneficial effects of the utility model are: the utility model is by single raceway blowout patche and a two raceway seat ring of two different sizes, make turntable bearing bearing capacity height, limit speed higher, noise is little, the reliability height of equipment, simple in structure, easy installation and removal, can satisfy the needs that people produce.
Description of drawings
Fig. 1 is the structural representation of a kind of turntable bearing of the utility model.
(being designated among the figure: 1, single raceway blowout patche; 2, two raceway seat rings; 11, holder; 111, steel ball; 21, following retainer; 22, tapped hole is installed.)
