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
The present invention relates to mine equipment formula excavator, particularly a kind of mine excavator encoder and synchronous linkage that rotates of its output shaft of being used for.
Background technology
Encoder is that mine excavator is spacing and measure a kind of accurate apparatus of stroke, and the protection mine excavator promotes and dipper crowding gear, is installed in pushing jackshaft and hoisting drum axle axle head.Synchronism in order to guarantee that encoder and output shaft rotate during installation needs encoder and output shaft installing and connecting apparatus between the two.Because the axiality that encoder needs requires than higher,, encoder is damaged in case the radial and axial power of bigger disalignment is arranged; If it is not firm to connect, also rotation is asynchronous easily, makes that measured value and actual speed are inequality.
At present, rubber flexible coupling is adopted in being connected of output shaft of mining excavator and encoder, as shown in Figure 3: excavator turning cylinder 10 passes end cap 11 and stretches out axle head, between excavator turning cylinder 10 and encoder 12, directly links together by rubber flexible coupling 13.Encoder 12 is installed on the fixed head 6, and fixed head 6 is installed on the protective cover 7, and protective cover 7 can be installed on the end cap 11 of excavator by base 8.This rubber flexible coupling, because the restriction of encoder fixed form, the axiality between encoder and the output shaft can't guarantee.Prior art does not still have the shaft coupling that suitable output shaft of mining excavator and encoder can the normal delivery rotating speeds under big malalignment situation.
Summary of the invention
Purpose of the present invention is intended to overcome the shortcoming of prior art, the linkage of a kind of output shaft of mining excavator and encoder is provided, solution is giving no thought under the coaxial situation, can effectively transmit the problem of output speed between encoder and excavator output shaft.
The present invention is achieved through the following technical solutions:
The linkage of a kind of output shaft of mining excavator and encoder; between excavator output shaft and encoder; link together by a kind of flexible axle linkage; encoder is installed on the fixed head; fixed head is installed on the protective cover; protective cover can be installed on the end cap of excavator by base; it is characterized in that: described flexible axle linkage is by flexible axle; flexible pipe; key; dog screw; connector is formed; the two ends of flexible axle is connected with connector; the connector of flexible axle one end links together by dog screw and key and excavator output shaft, and the connector of the flexible axle other end links together by the output shaft of dog screw and key and encoder.
The outside of described flexible axle is set with the protection flexible pipe.
Described flexible axle and connector are fixed together by the mode of compacting.
Described flexible axle is that a kind of bend radius is the Bowden cable of 5mm less than 30mm, external diameter.
The present invention owing between excavator output shaft and encoder, adopt the flexible axle linkage of being made up of flexible axle, flexible pipe, key, dog screw, connector, becomes the rotation transmission that no axiality requires compared with the prior art.Not only can effectively reduce the infringement frequency of encoder, prolong the application life of encoder; And guaranteed the certainty of measurement of encoder, can also improve the operational reliability of equipment.
Description of drawings
Fig. 1 is the front view of the linkage of a kind of output shaft of mining excavator and encoder;
Fig. 2 is the A-A sectional view of Fig. 1;
Fig. 3 is the linkage schematic diagram that prior art adopts rubber flexible coupling.
The present invention is further illustrated by preferred embodiment below in conjunction with accompanying drawing.
The specific embodiment
As shown in Figure 1, 2, the linkage of a kind of output shaft of mining excavator and encoder is made up of flexible axle 1, flexible pipe 2, key 3, dog screw 4, connector 5, fixed head 6, protective cover 7, base 8, outlet board 9, output shaft 10, end cap 11, encoder 12.Excavator turning cylinder 10 passes end cap 11 and stretches out axle head; between excavator output shaft 10 and encoder 12; link together by a kind of flexible axle linkage of forming by flexible axle 1, flexible pipe 2, key 3, dog screw 4, connector 5; encoder 12 is installed on the fixed head 6; fixed head 6 is installed on the protective cover 7, and protective cover 7 can be installed on the end cap 11 of excavator by base 8.The two ends of described flexible axle 1 is connected with connector 5, the connector 5 of flexible axle 1 one ends links together with excavator output shaft 10 by dog screw 4 and key 3, and the connector 5 of flexible axle 1 other end links together by the output shaft of dog screw 4 and key 3 and encoder 12.
The outside of described flexible axle 1 is set with protection flexible pipe 2.
Described flexible axle 1 is fixed together with the mode of connector 5 by compacting.
Described flexible axle 1 is that a kind of bend radius is the Bowden cable of 5mm less than 30mm, external diameter, and the system of curling up about steel wire forms, and flexible axle is an outsourcing piece.Flexible axle has certain anti-twist ability on the one hand, under the situation that satisfies the encoder rotating torque, can not twist; Its radius of curvature R＜30mm can guarantee any direction transmission within very short distance on the other hand, and distance is long does not more have concentricity requirement more.Guarantee that under the out-of-alignment situation between output shaft and the encoder accurate transfer is rotated.
When rotating output, joint 5 is at first accepted rotation, because the fixing of key 3 can be delivered to rotation flexible axle 1, is delivered to encoder 12 by identical mode again.Can overcome axial force by the hole on dog screw 4 and the output shaft when axial force, dog screw 4 also can transmit rotation simultaneously, plays double protection.Connector 5 is connected with the compacting of flexible axle 1 and can transmits rotating reliably.
The rotation data that the present invention can transmit output shaft accurately is to encoder, thereby data are delivered to master control system, effectively the rotation of control appliance.
