Description
Technical field
The utility model relates to a kind of reversing chassis rotary encoder.
Background technology
In engineering machinery field, adopt the swinging mechanism design more and more widely between upper body that is connected with equipment and the underframe, some engineering machinery requires the relative rotating angle between upper body and the underframe to need control.Bore the needs in same hole as rotary drilling rig owing to circulate, bearing accuracy in order to guarantee to bore same hole, need take mode that its revolution is accurately resetted, the angle of revolution of its upper body is to extract rotary angle signal by rotary encoder, and controlled hydraulic system work decides the anglec of rotation.But existing rotary encoder mounting means, a kind of be rotary encoder with get on the bus fixing, the input shaft of scrambler and central swivel coupling center fixation, central swivel coupling is fixed on the underframe; Another kind is a rotary encoder and get on the bus fixingly, and the input shaft of scrambler adopts band transmission extraction signal with central swivel coupling.First kind of mounting means, fixing of scrambler input shaft and central swivel coupling center, concentricity can not guarantee, the revolution positioning error is big, simultaneously, owing to be subjected to the restriction of central swivel coupling central space position, the stationary shaft at scrambler input shaft and central swivel coupling center is less, service time is a little long, can get rusty and twists off damage; Second kind of mounting means, because driving-belt exists relative slip with belt pulley, belt driver is loosening easily under the vibration equipment influence, it is poor that belt connects impact resistance, the data distortion that causes rotary encoder to collect, the revolution positioning error is big, can not guarantee the requirement of boring aperture.In addition, parts such as driving-belt itself also exist environment temperature comparatively responsive, and are aging easily, serviceability instability, problems such as maintenance cost height.
The utility model content
The purpose of this utility model provides a kind of angle of revolution precision height of measuring, and resets accurately stable work in work, the reversing chassis rotary encoder that maintenance cost is low.
Reversing chassis rotary encoder of the present utility model, comprise rotary middle spindle, ring gear around rotary middle spindle, be installed in around upper body on the rotary middle spindle and the rotary encoder that is installed on the upper body, described ring gear is fixed on the underframe, described ring gear closes mutually with gear on the gear shaft age, and gear shaft is that the centre of gyration can be installed on the upper body rotationally with the rotary middle spindle, and an end of gear shaft links to each other with the input shaft of described rotary encoder.
Reversing chassis rotary encoder of the present utility model, the upper/lower terminal of wherein said gear shaft is respectively installed with bearing, each bearing holder (housing, cover) is contained in the axle sleeve, and the lateral wall and the web joint of axle sleeve are fixedly linked, and web joint adopts a plurality of being bolted on the described upper body.
Reversing chassis rotary encoder of the present utility model, an end of wherein said gear shaft adopt the connecting shaft cover to link to each other with the input shaft of described rotary encoder.
Reversing chassis rotary encoder of the present utility model, wherein said rotary encoder adopt screw retention at the top of protective cover, and protective cover adopts the upper surface of screw retention at described web joint.
Reversing chassis rotary encoder of the present utility model, the sidewall of wherein said protective cover is provided with viewport.
Reversing chassis rotary encoder of the present utility model, wherein each described bearing adopts the hole to locate with collar with collar and/or axle.
Reversing chassis rotary encoder of the present utility model, in use, when upper body rotates with the centre of gyration, upper body can be with gear shaft to rotate with the centre of gyration, gear on the gear shaft also can be along with gear shaft rotates with the centre of gyration, meanwhile, because gear closes mutually with ring gear on being fixed on underframe age, gear is that the centre of gyration rotates with the gear shaft thereby make, the gear shaft input shaft of driven rotary scrambler again rotates, thereby the signal that scrambler is gathered is accurate, and electric control system can accurately be measured the angle of revolution of upper body.Because gear-driven transmission accuracy is high, so Operation of Rotary Pile Drill of the present utility model chassis rotary encoder has stable work in work, maintenance cost is low, the high characteristics of measuring of angle of revolution precision.
Below in conjunction with accompanying drawing this practical reversing chassis is described further with rotary encoder.
Description of drawings
Fig. 1 is the main pseudosection of reversing chassis of the present utility model with the structural representation of rotary encoder.
Embodiment
As seen from Figure 1, reversing chassis rotary encoder of the present utility model, comprise rotary middle spindle (not drawing among the figure), ring gear 1 around rotary middle spindle, be installed in around upper body on the rotary middle spindle 2 and the rotary encoder 3 that is installed on the upper body 2, ring gear 1 is fixed on the underframe, ring gear 1 closes mutually with gear 5 on the gear shaft 4 age, gear shaft 4 is that the centre of gyration can be installed on the upper body 2 rotationally with the rotary middle spindle, and an end of gear shaft 4 adopts connecting shaft cover 8 to link to each other with the input shaft of rotary encoder 3.Rotary encoder 3 adopts screw retention at the top of protective cover 9, and protective cover 9 adopts the upper surface of screw retention at web joint 7.The sidewall of protective cover 9 is provided with viewport 10.
Upper/lower terminal at gear shaft 4 is respectively installed with bearing 11, and each bearing 11 is sleeved in the axle sleeve 6, and each bearing 11 adopts the hole to locate with collar with collar and/or axle.The lateral wall of axle sleeve 6 and web joint 7 are fixedly linked, and web joint 7 adopts a plurality of being bolted on the upper body 2.
Reversing chassis rotary encoder of the present utility model, in use, when upper body 2 rotates with the centre of gyration, upper body 2 can be with gear shaft 4 to rotate with the centre of gyration, gear 5 on the gear shaft 4 also can be along with gear shaft 4 rotates with the centre of gyration, meanwhile, because gear 5 closes mutually with ring gear 1 on being fixed on the chassis age, gear 5 is that the centre of gyration rotates with gear shaft 4 thereby make, gear shaft 4 input shaft of driven rotary scrambler 3 again rotates, thereby electric control system can be measured the angle of revolution of upper body 2 accurately.Because gear-driven transmission accuracy height, so reversing chassis rotary encoder of the present utility model has stable work in work, maintenance cost is low, the high characteristics of measuring of angle of revolution precision.
