Description
Technical field
The utility model belongs to equipment mounting technique field, and particularly, the utility model relates to a kind of device be arranged on by encoder on speed reducer output shaft.
Background technology
Encoder is worked out signal or data, being converted to can in order to communication, the equipment of the signal form of transmission and storage, usually speed end and low speed end is arranged on, usually motor afterbody shaft extension place is arranged on when being arranged on speed end, general installing mechanism is all complete providing, install more convenient, precision is higher, but sometimes because engineering site spatial limitation, motor side cannot be installed, reductor high-speed side can only be arranged on, installation now just becomes the particular/special requirement of a non-general character, there is no mode standard at present, general way utilizes the axis hole on reductor high speed shaft to process screw thread, again encoder is installed after in fixed with this, but this kind of method is limited to the axiality of high speed shaft upper screwed hole, it is very difficult for processing the very high screw thread of axiality, encoder is directly installed on speed end in addition, if axiality is bad, encoder can be caused to shake bigger than normal, the code-disc of fragile encoder, encoder damages frequent.
Utility model content
The purpose of this utility model is, a kind of device be arranged on by encoder on speed reducer output shaft is provided, this device make use of the excircle orientation of output shaft, eliminate screwed hole of centre mismachining tolerance, avoid the code-disc damage significantly swinging after encoder is installed and bring, accurate positioning is installed, quick and convenient.
For achieving the above object, the utility model have employed following technical scheme:
A kind of device encoder is arranged on speed reducer output shaft, described device comprises the first assembly 4 be set on speed reducer output shaft 6, and the medial surface of described first assembly 4 one end fits in and the lateral surface of speed reducer output shaft 6 (is equivalent to formation first mating surface 5) to realize the first assembly 4 and locates with the axiality of speed reducer output shaft 6; The other end axiality of described first assembly 4 connects the second assembly 3, and described second assembly 3 center arranges encoder fixed axis 1, the axis of described encoder fixed axis 1 and the dead in line of speed reducer output shaft 6.
Preferably, flange is adopted to be connected with the fit system of groove between described first assembly 4 and the second assembly 3.
Further preferably, described first assembly 4 arranges groove, described second assembly 3 is arranged and the flange of fit depressions, and this flange inserts in groove, and the lateral surface of flange fits on the medial surface of groove and (is equivalent to formation second mating surface 2).
Still more preferably, the shape of described groove and flange is circular.
Preferably, the shape of described first assembly 4 is dish-type.
Preferably, the shape of described second assembly 3 is dish-type.
Further preferably, described dish-type is collar plate shape.
Preferably, bolt is adopted to fix between described first assembly 4 and speed reducer output shaft 6.
Preferably, bolt is adopted to fix between described first assembly 4 and the second assembly 3.
The utility model directly can not utilize reductor axis hole screw thread when deceleration pusher side installs encoder, only utilize the fastening effect of screw thread, the cylindrical of reductor speedy carding process axle is utilized to carry out axiality location, because no matter whether center threaded coaxial, the cylindrical of its output shaft is a standard cylinder, by controlling the axiality of parts processing, then can realize the coaxial rotation of encoder very well.
The concrete installation method of device described in the utility model is: the first assembly 4 is arranged on the axle head of speed reducer output shaft 6, relies on the bolt of output shaft end to realize fixing, relies on the first mating surface 5 to realize axiality location; Second assembly 3 is arranged on the first assembly 4, relies on the second mating surface 2 to realize axiality location, relies on bolt to realize fixing.The mating surface of the second assembly 3, first assembly 4 and the center of encoder fixed axis all will with speed reducer output shaft 6 center line for benchmark, and according to the requirement of output speed, rotating speed is higher, corresponding raising parts axiality machining accuracy.Mating surface 2 and 5 is processed according to H7/h6 when assembling, and substantially can meet the requirement of all conventional coders installation accuracies.
The diameter of the utility model encoder output shaft 1 is processed according to the size of required encoder axis hole, is fixed on by encoder on this axle and can meets use.
The utility model make use of excircle orientation dexterously, eliminates screwed hole of centre mismachining tolerance, avoids the code-disc damage significantly swinging after encoder is installed and bring, installs accurate positioning, quick and convenient.
