Problems solved by technology

For this kind of rubber elastic coupling, due to the limitation of the encoder fixing method, the coaxiality between the encoder and the output shaft cannot be guaranteed.
In the prior art, there is no coupling suitable for the output shaft of the mining excavator and the encoder to transmit the speed normally under the condition of large misalignment

Embodiment Construction

[0015] Such as figure 1 , 2 As shown, a connection device between the output shaft of a mining excavator and the encoder is composed of flexible shaft 1, hose 2, key 3, positioning screw 4, connector 5, fixed plate 6, protective cover 7, base 8, and outlet It is composed of plate 9, output shaft 10, end cover 11 and encoder 12. The excavator rotating shaft 10 passes through the end cover 11 and extends out of the shaft end. Between the excavator output shaft 10 and the encoder 12, it passes through a flexible shaft 1, a hose 2, a key 3, a positioning screw 4, and a connecting head 5. The composed flexible shaft connecting devices are connected together, the encoder 12 is installed on the fixed plate 6, the fixed plate 6 is installed on the protective cover 7, and the protective cover 7 can be installed on the end cover 11 of the excavator through the base 8. The two ends of the flexible shaft 1 are fixedly connected with connectors 5, the connector 5 at one end of the flexible...

Abstract

The invention provides a connecting device for an output shaft of a mining excavator and an encoder, and relates to a mining mechanical excavator, which can effectively transfer output rotation speed between the encoder and the excavator output shaft in spite of coaxiality. The flexible axis connecting device is characterized by consisting of a flexible axis 1, a hose 2, keys 3, positioning screws 4 and connectors 5, wherein both ends of the flexible axis 1 are fixedly connected with the connectors 5; the connector 5 at one end of the flexible axis 1 is connected with the excavator output shaft 10 through the positioning screws 4 and the keys 3; and the connector 5 at the other end of the flexible axis 1 is connected with an output shaft of the encoder 12 through the positioning screws 4 and the keys 3. The connecting device transfers the rotation without coaxial requirements, can effectively reduce the damage frequency of the encoder, prolongs the service life of the encoder, ensures the measurement accuracy of the encoder, and improves the operational reliability of equipment.

Description

Technical field [0001] The invention relates to a mining mechanical excavator, in particular to a connecting device for synchronous rotation of an encoder of a mining excavator and its output shaft. Background technique [0002] Encoder is a kind of precision equipment for limit and measuring stroke of mining excavator. It protects the lifting and pushing mechanism of mining excavator. It is installed on the shaft end of pushing intermediate shaft and lifting drum shaft. In order to ensure the synchronization of the rotation of the encoder and the output shaft during installation, it is necessary to install a connecting device between the encoder and the output shaft. Since the encoder requires relatively high coaxiality, once there are relatively large radial and axial forces of different shafts, the encoder can be damaged; if the connection is not secure, it is easy to rotate out of synchronization, making the measured value and actual The speed is not the same. [0003] At pre...
