Abstract
The utility model relates to a servomotor installation structure with a self-aligning function, which comprises a support connected to a servomotor of a water turbine control loop and a ground base. The servomotor installation structure with the self-aligning function is characterized in that a spherical joint is installed between the servomotor and the support, one end of the spherical joint is in threaded connection with the servomotor, the other end of the spherical joint is in spherical contact with the support, and a pressing plate is sleeved respectively on the outer periphery of the spherical joint and the outer periphery of the spherical joint at the support connecting end and installed respectively on the support through fastening parts. By adopting the technical scheme, the servomotor installation structure with the self-aligning function achieves the self-aligning installation function of the servomotor, is simultaneously not sensitive to installation deflection of the servomotor and reduces installation requirements for installation and ensures stable operation of the control loop and flexible movement of a piston rod. In addition, the spherical joint also has the advantages of even stress, large load bearing capacity, convenience in installation and maintenance and the like.
Description
Technical field
The utility model belongs to hydro-electric power generating equipment water turbine supplementary equipment technical field, particularly a kind of servomotor mounting structure with self-aligning function.
Background technique
When water turbine adopts servomotor structural adjustment aperture; Need servomotor and special connecting head to accomplish, guarantee self-aligning through connecting head, insensitive to deflection; Stressed even; And can bear very high load, its needs to satisfy the various operating modes of water turbine, will guarantee that simultaneously servomotor can be convenient to install and safeguard.Be hinged or other connection because existing various servomotor connects design; These Placements can not well produce a desired effect; Cause the operation of control ring not steady, also have complex structure in addition, defectives such as component are more, fabricating cost is high, discontinuity.
Summary of the invention
The utility model provides a kind of even, bearing capacity servomotor mounting structure with self-aligning function bigger, convenient for installation and maintenance simple in structure, stressed for solving the technical problem that exists in the known technology.
The technological scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
A kind of servomotor mounting structure with self-aligning function; Comprise and the servomotor of water turbine control ring, the bearing that is connected with ground; It is characterized in that: between said servomotor and the bearing spherical joint is installed, said spherical joint one end is threaded with servomotor, contacts for sphere between the other end of said spherical joint and the bearing; Be set with pressing plate on the spherical joint excircle of said spherical joint and bearing connecting end, said pressing plate is installed on the bearing through fastening piece.
The utility model can also adopt following technological scheme:
The joint of said spherical joint and bearing is provided with oilhole.
Advantage and the good effect that the utlity model has are: because the utility model adopts technique scheme, between servomotor and bearing, spherical joint is installed, has been realized the installation self-aligning function of servomotor; Also insensitive to the installation deflection of servomotor simultaneously, reduced installation requirement, guaranteed operating steadily of control ring; It is flexible that piston rod moves; And spherical joint also have stressed evenly, it is big to bear load carrying capacity, is convenient to advantages such as installation and maintenance.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is bearing and ground linkage structure schematic representation.
Among the figure: 1, control ring; 2, servomotor; 3, stone bolt; 4, bearing; 5, spherical joint; 6, pressing plate; 7, fastening piece; 8, oilhole.
Embodiment
For further understanding summary of the invention, characteristics and the effect of the utility model, the following examples of giving an example now, and conjunction with figs. specifies as follows:
See also Fig. 1 and Fig. 2; A kind of servomotor mounting structure with self-aligning function; Comprise the bearing 4 that is connected with ground with the servomotor 2 of water turbine control ring 1, through stone bolt 3; Spherical joint 5 is installed between said servomotor 2 and the bearing 4, and said spherical joint 5 one ends are threaded with servomotor 2, contact for sphere between the other end of said spherical joint 5 and the bearing 4; Be set with pressing plate 6 on spherical joint 5 excircles of said spherical joint 5 and bearing 4 connecting ends, said pressing plate 6 is installed on the bearing 4 through fastening piece 7.Lubricated in order to improve between the surface of contact, be provided with oilhole 8 in the joint of said spherical joint and bearing.
Said structure has been realized the installation self-aligning function of servomotor, and is also insensitive to the installation deflection of servomotor simultaneously; Reduced installation requirement; Guaranteed operating steadily of control ring, it is flexible that piston rod moves, and spherical joint also has stressed even; It is big to bear load carrying capacity, is convenient to advantages such as installation and maintenance.
