Abstract
The invention discloses a novel high-precision slewing support. The novel high-precision slewing support comprises a turbine device and a worm device; the turbine device comprises a gear wheel, a base seat and an end cover, the gear wheel is fixed to the base seat through the end cover, the axial contact face of the gear wheel and the base seat is provided with a plane bearing, and the radial contact face of the gear wheel and the base seat is provided with conical roller bearings. The structural design is reasonable, the capacity for increasing axial stress suffering can be achieved by using the conical roller bearings and the plane bearing in a matched mode, the height and the size of a machine are reduced, the structure is compact, the installation and maintenance are convenient, the use stability is improved, and the slewing precision is improved.
Description
Technical field
The present invention relates to mechanical field, especially relate to novel high-precision pivoting support.
Background technique
In traditional use bearing pack process, tapered roller bearing needs two to use guarantee using effect together, not so there will be the phenomenon that bearing is subject to the disengaging of reverse responsive to axial force, although bear that radial force is large but radial internal clearance is also very large and the axial force of bearing is little, rotating accuracy is not high, two tapered roller bearings use the height adding machine together, vibrational power flow is not compact, deep groove ball bearing group radial internal clearance is large, and radial force is much less than tapered roller bearing group, usage requirement can not be met.
Summary of the invention
The present invention is the problem solving above-mentioned proposition, for herein is provided a kind of novel high-precision pivoting support, comprise turbine device and endless screw apparatus, described turbine device comprises gear, pedestal and end cap, described gear is fixed on pedestal by end cap, the axial surface of contact of described gear and pedestal is provided with plane bearing, the radial surface of contact of described gear and pedestal is provided with tapered roller bearing.
As preferably, described gear is provided with tapped hole.
The invention has the beneficial effects as follows: reasonable in design of the present invention, can by tapered roller bearing and plane bearing with the use of reaching the ability increasing and axially bear pressure, reduce machine height and volume, compact structure, easy to installation and maintenance, strengthen stability in use, increase rotating accuracy.
Accompanying drawing explanation
Examples of the present invention will be described by way of reference to the accompanying drawings, wherein:
Fig. 1 is complete section schematic diagram of the present invention;
In figure: 1, turbine device; 2, endless screw apparatus; 3, gear; 3.1, tapped hole; 4, pedestal; 5, end cap; 6, plane bearing; 7, tapered roller bearing.
Embodiment
All features disclosed in this specification, or the step in disclosed all methods or process, except mutually exclusive feature and/or step, all can combine by any way.
Arbitrary feature disclosed in this specification (comprising any accessory claim, summary and accompanying drawing), unless specifically stated otherwise, all can be replaced by other equivalences or the alternative features with similar object.That is, unless specifically stated otherwise, each feature is an example in a series of equivalence or similar characteristics.
A kind of novel high-precision pivoting support as shown in Figure 1, comprise turbine device 1 and endless screw apparatus 2, described turbine device 1 comprises gear 3, pedestal 4 and end cap 5, described gear 3 is fixed on pedestal 4 by end cap 5, the axial surface of contact of described gear 3 and pedestal 4 is provided with plane bearing 6, the radial surface of contact of described gear 3 and pedestal 4 is provided with tapered roller bearing 7.
Described gear 3 is provided with tapped hole 3.1.
Described end cap 5 is fixedly connected with bolt by pin with pedestal 4.
In use, the combination of tapered roller bearing 7 and plane bearing 6 can increase the axial pressure of bearing further, reduce radial internal clearance, moment acts between gear 3 and pedestal 4, tapped hole 3.1 is for connecting external means, the position of plane bearing 3 is at the line of action place of power, so large power of toppling can be born, end cap 5 is fixed on pedestal 4 by bolt and pin, pin is had to be connected with bolt, achieve the conversion of tightening force and shearing force, make bearing pack stressed, the play of tapered roller bearing can be regulated by bolt, realize precision-fit, increase rotating accuracy.
Reasonable in design of the present invention, can by tapered roller bearing and plane bearing with the use of reaching the ability increasing and axially bear pressure, reduce machine height and volume, compact structure, easy to installation and maintenance, strengthen stability in use, increase rotating accuracy.
The present invention is not limited to aforesaid embodiment.The present invention expands to any new feature of disclosing in this manual or any combination newly, and the step of the arbitrary new method disclosed or process or any combination newly.
