Abstract
The utility model relates to a buffer structure of an encoder, which is used on a rear end shaft of a connecting shaft of the encoder and a motor. The encoder is installed on an extending shaft of the motor, an end surface of the encoder is connected with a connecting plate through a screw, a spring is arranged in a connecting screw hole of the connecting plate, and the screw is connected with the connecting plate through the spring to ensure that the encoder is elastically connected with the connecting plate. The connecting plate is fixed on the end surface of the motor through the screw, and the screw is directly fixed with a fixed screw hole on the connecting plate. The buffer structure adopting the design can guarantee that the encoder is axially shifted along with the extending shaft when the extending shaft is axially shifted, and has the function of elastic connection, thereby ensuring that the encoder can bear the axial shifting within the allowable elastic range and ensuring the service life of the encoder.
Description
Technical field
The utility model relates to the encoder syndeton.
Background technology
As everyone knows, encoder is fixed on the extension shaft of motor usually.Motor is in rotating process, and the motor shaft time rotational can have certain stretching, particularly large-scale motor, and its dilatability can reach 3-5mm.The fixed form that encoder is commonly used all is to adopt directly fixingly, so when the dilatability of extension shaft is very big, just easily encoder is brought certain infringement, influences the useful life of encoder.
The utility model content
The purpose of this utility model provides a kind of encoder buffer structure, is the fixed structure of encoder, can solve in the motor extension shaft rotation process owing to dilatability influences the encoder problem in useful life.
The purpose of this utility model is to be achieved through the following technical solutions:
The encoder buffer structure, be applied on the connecting axle end face of encoder and motor, encoder is installed on the extension shaft of motor, the end face of encoder is connected on the connecting plate by screw, in the attachment screw hole of described connecting plate, be provided with spring, screw passes spring and is connected with connecting plate, guarantees that encoder has elasticity with being connected of connecting plate.On the motor end face, the fixing screw hole on described screw and the connecting plate is directly fixing by screw for described connecting plate.
Buffer structure by above-mentioned design, when the extension shaft that can guarantee motor has axial endplay, encoder is along with extension shaft carries out axial play together, can play the effect that elasticity connects, so just can guarantee that encoder bears the axial endplay that allows in the elastic range, guarantees the useful life of encoder.
Description of drawings
With embodiment the utility model is described in further detail with reference to the accompanying drawings below.
Fig. 1 is the johning knot composition of the described encoder buffer structure of the utility model embodiment;
Fig. 2 is the structure chart of connecting plate.
Embodiment
Shown in Fig. 1-2, the encoder buffer structure, be applied to being connected on the end face of encoder 1 and motor, encoder 1 is installed on the extension shaft 2 of motor, the side of encoder 1 is connected on the connecting plate 3 by screw 4, be provided with spring 5 in the attachment screw hole 7 of described connecting plate 3, screw 4 passes spring 5 and is connected with connecting plate 3, guarantees that encoder 1 has elasticity with being connected of connecting plate 3.Described connecting plate 3 by screw on the motor end face, fixing screw hole 6 on described screw and the connecting plate 3 is directly fixing, for making structure representation convenient, do not provide the structure of motor among the figure, also do not provide the signal that is connected of screw and motor, but those skilled in the art can implement voluntarily according to above-mentioned narration.
In the process of implementing, firm for making structure, can be with fixing screw hole 6 and attachment screw hole 7 staggered, even layouts.The quantity in fixing screw hole 6 and attachment screw hole 7 can design as required, and itself is not subjected to the restricted number of screw hole structure of the present utility model.
Buffer structure by above-mentioned design, when the extension shaft that can guarantee motor has axial endplay, encoder is along with extension shaft carries out axial play together, can play the effect that elasticity connects, so just can guarantee that encoder bears the axial endplay that allows in the elastic range, guarantees the useful life of encoder.
