Abstract
The utility model discloses a bidirectional heavy-load support shaft, and belongs to the field of positioning platform support shafts. The support shaft comprises a stand column (1), a deep groove ball bearing (2), an angular contact ball bearing (4), a stand column fixing plate (5) and an upper plate connector (6), wherein one end of the stand column (1) is connected with the stand column fixing plate (5); the other end of the stand column (1) is connected with an upper plate working table board (3); the deep groove ball bearing (2) is sleeved at the outer side of the stand column (1) and positioned below the upper plate working table board (3); the angular contact ball bearing (4) is sleeved at the outer side of the stand column (1) and positioned below the deep groove ball bearing (2). By the manner of matching the deep groove ball bearing (2) and the angular contact ball bearing (4), heavy load can be endured in the axial direction or radial direction during high-speed or low-speed operation, so that the requirements of high precision and heavy load are met.
Description
Technical field
The utility model relates to a kind of bidirectional heavy-load back shaft, belongs to locating platform supporting axle field.
Background technique
In vision contraposition field, be that movement velocity is fast to the job requirement of bit platform, bearing load is heavy, the aligning accuracy height.What the present supporting axle to bit platform was selected for use mostly is deep groove ball bearing or angular contact ball bearing, minority is selected the intersection ball bearing for use, yet, deep groove ball bearing can only bear radial load, and a little less than the thrust load ability to bear, it is moving to produce the axial displacement string, angular contact ball bearing is stronger to the thrust load ability to bear, but to load ability to bear radially a little less than, it is moving to produce the radial displacement string, can feel painstaking and intersect ball bearing under the situation of heavy duty.
The model utility content
The utility model is the defective that exists at existing back shaft, proposes a kind of bidirectional heavy-load back shaft.
The utility model adopts following technological scheme for solving above technical problem:
A kind of bidirectional heavy-load back shaft comprises column, deep groove ball bearing, angular contact ball bearing, column fixed plate and goes up connector for substrate; One end of described column is connected with the column fixed plate; The other end of described column is connected with the upper plate table top; Described deep groove ball bearing is placed in the outside of column, and its position is positioned at the below of upper plate table top; Described angular contact ball bearing is placed in the outside of column, and its position is positioned at the below of deep groove ball bearing; The described connector for substrate of going up is connected with the upper plate table top by double-screw bolt.
As further optimized project of the present utility model, comprise that is also gone up a connector for substrate gland; Described upward connector for substrate gland covers the bottom at last connector for substrate.
As further optimized project of the present utility model, described deep groove ball bearing is the biserial deep groove ball bearing.
The utility model adopts above technological scheme, compared with prior art has following technique effect:
The mode that the utility model adopts deep groove ball bearing and angular contact ball bearing to cooperatively interact and use reaches axially, in the radial direction no matter be at a high speed or can both bear heavy load during low cruise, thereby satisfies highi degree of accuracy, the requirement of heavy load.
Bottom of going up connector for substrate of the present utility model is provided with the connector for substrate gland, can prevent connector for substrate generation axial motion on platform is in movement process.
The utility model adopts the biserial deep groove ball bearing, and this bearing has stronger load-carrying ability.
Description of drawings
Fig. 1 is structural drawing of the present utility model.
Number in the figure: 1, column; 2, deep groove ball bearing; 3, upper plate table top; 4, angular contact ball bearing; 5, column fixed plate; 6, go up connector for substrate; 7, go up the connector for substrate gland; 8, double-screw bolt; 9, motor.
Embodiment
Below in conjunction with accompanying drawing the technical solution of the utility model is done introduction in further detail:
Structural drawing of the present utility model comprises column 1, deep groove ball bearing 2, angular contact ball bearing 4, column fixed plate 5, goes up connector for substrate gland 7 and go up connector for substrate 6 as shown in Figure 1; Described deep groove ball bearing 2 is the biserial deep groove ball bearing, and this bearing has stronger load-carrying ability; One end of described column 1 is connected with column fixed plate 5; The other end of described column 1 is connected with upper plate table top 3, and this column 1 is mainly used in transmitting the moment that motor 9 produces; Described deep groove ball bearing 2 is placed in the outside of column 1, and its position is positioned at the below of upper plate table top 3, is mainly used in bearing radial force and certain axial force, and transmits a precompression to angular contact ball bearing 4; Described angular contact ball bearing 4 is placed in the outside of column 1, and its position is positioned at the below of deep groove ball bearing 2, is mainly used in bearing axial force, and bears certain radial force under it is subjected to the situation of precompression; Gap between the end face of described deep groove ball bearing 2, angular contact ball bearing 4 and column 1 compresses by locking nut, makes angular contact ball bearing 4 axial motion can not take place when being subjected to radial force; The described connector for substrate 6 of going up is connected with upper plate table top 3 by double-screw bolt 8, is mainly used in bearing the weight on the upper plate table top 3; The described connector for substrate gland 7 of going up covers in the bottom of last connector for substrate 6, is used for preventing that platform connector for substrate 6 on movement process from axial motion taking place.
When motor 9 rotates, motor 9 passes torque to upper plate table top 3 by column fixed plate 5 and column 1 successively, upper plate table top 3 is along the moving direction movement therewith of motor 9, deep groove ball bearing 2 and angular contact ball bearing 4 cooperatively interact, and bear jointly and transmit radial force and the axial force of coming in the machine movement process.
The above only is embodiment of the present utility model; be not so limit claim of the present utility model; every equivalent structure or equivalent flow process conversion that utilizes the utility model specification and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present utility model.
