Abstract
A novel three-collar bearing with high precision comprises an outer ring (1), steel balls (2), a middle ring (3), retainers (4) and an inner ring (5), wherein, the middle ring (3) is arranged in the middle of the inner and the outer rings (5 and 1), the steel balls (2) are installed on the rollaway nests of the inner, the middle and the outer rings (5, 3 and 1), and the steel balls (2) are respectively installed in the cage pocket of the retainers (4). The bearing can replace two sets of common two-collar bearings in the using of a north-stabilized indicator, and also can reduce the structural size greatly, thereby reducing the whole structural size of the north-stabilized indicator, and improving the portability of the whole north-stabilized indicator.
Description
Technical field
The utility model belongs to technical field of bearings, specially refers to a kind of novel high-precision three collar bearings.
Background technique
What refer to use in the northern instrument in existing highi degree of accuracy is common two collar bearings, the main problem that exists is in the use: need two rotational support owing to refer to northern instrument, the inner gyroscope that connects, the outside theodolite that connects, so need existing two collar bearings of two covers, this just makes the northern instrument volume of whole finger bigger, and influence is portable.
Summary of the invention
At above-mentioned existing problem, the utility model has designed a kind of novel high-precision three collar bearings, this bearing is referring to that northern instrument can substitute common two collar bearings of two covers in using, physical dimension is reduced greatly, thereby reduce to refer to the overall structure size of northern instrument, improved the portability that refers to northern instrument complete machine.
For achieving the above object, the utility model has adopted following technological scheme:
Described novel high-precision three collar bearings are made of outer ring, steel ball, centre circle, retainer, inner ring, wherein inside and outside circle intermediate configurations centre circle, and interior, in, on the raceway of outer ring steel ball is installed, these steel balls are contained in respectively in the pocket hole of retainer separately.
Owing to adopt aforesaid technological scheme, the utlity model has following superiority:
1, this bearing is applied in highi degree of accuracy and refers in the northern instrument, has easy to usely, and running accuracy and sensitivity reach higher level, have improved system's installation precision, have reduced positioning error, realize the system architecture compactness.
2, this bearing not only can satisfy the needs that following highi degree of accuracy refers to northern instrument bearing, also can make highi degree of accuracy three collar bearings be used for size, precision, sensitivity and quality are had other accurate supporting of strict demand, fills up the blank of China's filbore.
Description of drawings
Fig. 1 is the utility model structural representation;
Among Fig. 1: 1-outer ring; 2-steel ball; 3-centre circle; 4-retainer; 5-inner ring.
Embodiment
As shown in Figure 1: novel high-precision three collar bearings of the present utility model are made of outer ring (1), steel ball (2), centre circle (3), retainer (4), inner ring (5), wherein inside and outside circle (5,1) intermediate configurations centre circle (3), and interior, in, on the raceway of outer ring (5,3,1) steel ball (2) is installed, these steel balls (2) are contained in respectively in the pocket hole of retainer (4) separately.
Between the inside and outside circle of common two collar bearings, increased a centre circle, two cover bearings have been formed respectively with inside and outside circle, the inner ring that promptly is equivalent to external bearings, the outer ring that is equivalent to internal bearings again, structure is very good, promptly satisfies the function of common two collar bearings of two covers, and physical dimension is reduced greatly, thereby reduce to refer to the overall structure size of northern instrument, improved the portability of complete machine.
Claims (1)
1, a kind of novel high-precision three collar bearings, it is characterized in that: this bearing is made of outer ring (1), steel ball (2), centre circle (3), retainer (4), inner ring (5), wherein inside and outside circle (5,1) intermediate configurations centre circle (3), and interior, in, on the raceway of outer ring (5,3,1) steel ball (2) is installed, these steel balls (2) are contained in respectively in the pocket hole of retainer (4) separately.
