Abstract
The utility model discloses a novel built -in shaft coupling of angle encoder, it relates to machine rotation axis precision measurement technology field. It kneads dough two including face no. 1, face no. 1 and two mutually perpendicular in the face, face no. 1 links to each other with the core component's that hollow shaft, bearing are formed outside rotatable part, and face no. 2 is connected with the shell lower cover, and face no. 1 is connected through the connecting portion phase with face no. 2, and a face built -in shaft coupling of kneading dough two components is whole monolithic stainless steel construction, is thickness 1.0 1.5mm. The utility model discloses beneficial effect does: its ability and hollow shaft coaxial arrangement has sufficient elastic deformation ability again to the elimination because of when installation the shell deflect the torsion that produces to the influence of encoder precision, and thickness is thin can satisfy constrictive space in the encoder.
Description
Technical field
This utility model relates to machine shaft running accuracy technical field, is specifically related to a kind of novel built-in shaft coupling of angular encoder.
Background technology
Angular encoder with built-in bearing is the accurate special equipment of angular surveying, is also the crucial closed loop location sensor of high precision machines axle running accuracy.Built-in bearing makes angular encoder have hollow shaft structure, this makes angular encoder can be conveniently mounted on the axle of machine, thus constitute direct position closed-loop control system, actual position information feedback control system according to the axle of machine, so can revise the deformation error that the axle of machine causes due to own wt, therefore can be greatly improved the position of rotation control accuracy of machine shaft.
The precision of angular encoder has much relations with encoder hollow axle with the deviation of shaft coupling and the elastic deformation deviation of shaft coupling, the space layout of the axle of machine also requires that angular encoder thickness is less simultaneously, this just requires built-in shaft joint to must be able to hollow axle to be co-axially mounted, there are again enough elastic deformabilities, the torsion that during to eliminate because installing, shell deflection the produces impact on encoder accuracy, and thickness is thin with space narrow in meeting encoder.
Utility model content
The purpose of this utility model is the defect for prior art and deficiency, there is provided a kind of simple in construction, angular encoder reasonable in design, easy to use novel built-in shaft coupling, it can be co-axially mounted with hollow axle, there are again enough elastic deformabilities, the torsion impact on encoder accuracy that during to eliminate because installing, shell deflection produces, and thickness is thin can meet encoder in narrow space.
In order to solve the problem existing for background technology, the technical solution adopted in the utility model is: it includes face one dough-making powder two；Described face one is mutually perpendicular to face two, face one is connected with the outer rotatable part of hollow axle, the core component of bearing composition, face two is connected with shell lower cover, face one is connected by connecting portion with face two, the built-in shaft coupling of face one dough-making powder two composition is overall monolithic stainless steel structure, and thickness is 1.0-1.5mm.
After using said structure, this utility model has the beneficial effect that it can be co-axially mounted with hollow axle, have again enough elastic deformabilities, the torsion impact on encoder accuracy that during to eliminate because installing, shell deflection produces, and thickness is thin can meet encoder in narrow space.

Description of reference numerals: face 1, face 22.
Detailed description of the invention
Below in conjunction with the accompanying drawings, this utility model is further described.
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with the drawings and the specific embodiments, this utility model is further elaborated.Should be appreciated that detailed description of the invention described herein, only in order to explain this utility model, is not used to limit this utility model.
As shown in Figure 1-Figure 3, this detailed description of the invention adopts the following technical scheme that it includes face 1, face 22；Described face 1 is mutually perpendicular to face 22, face 1 is connected with the outer rotatable part of hollow axle, the core component of bearing composition, face 22 is connected with shell lower cover, face 1 is connected by connecting portion with face 22, the built-in shaft coupling of face 1 dough-making powder 22 composition is overall monolithic stainless steel structure, and thickness is 1.2mm.
Orthogonal face 1 dough-making powder 22 is used to be connected with combinative structure and the shell lower cover of hollow axle, bearing etc. respectively, the position making face 1 dough-making powder 22 be connected is sufficiently fine, making it possess enough elastic deformation abilities, during to eliminate installation, shell deflects the impact brought.
Thickness according to the size Selection stainless steel material of angular encoder, shaft coupling is made to have the ability producing sufficiently resilient deformation, making face 1 dough-making powder 22 be mutually perpendicular to, face 1 is connected with the outer rotatable part of the core component that hollow axle, bearing etc. form, and makes hollow axle can rotate relative to shaft joint.
This detailed description of the invention can be co-axially mounted with hollow axle, has again enough elastic deformabilities, the torsion impact on encoder accuracy that during to eliminate because installing, shell deflection produces, and thickness is thin can meet encoder in narrow space.
The above, only in order to the technical solution of the utility model to be described and unrestricted, other amendment or equivalent that the technical solution of the utility model is made by those of ordinary skill in the art, without departing from the spirit and scope of technical solutions of the utility model, all should contain in the middle of right of the present utility model.
