Model utility content
Technical problem to be solved in the utility model is to provide a kind of vertical variable gear gearbox that can improve rig adaptive capacity.
Technical solutions of the utility model are as follows: a kind of rig vertical variable gear gearbox, comprise casing (1), its key is: at top fixing motor end cap (2) of described casing (1), this motor end cap (2) is installed motor (3), the output shaft of described motor (3) is set with driving gear (4), driving gear (4) engages with driven gear (5), described driven gear (5) is set on input gear (6), input gear (6) empty set is in the upper end of spline spindle (7), the bottom surface of casing (1) is stretched out in the lower end of this spline spindle (7), described input gear (6) engages with pagoda tooth (8), pagoda tooth (8) is arranged on rotatingshaft (9), the gear tooth (10) matched with pagoda tooth (8) is sleeved on spline spindle (7), circumferentially annular groove is offered described gear tooth (10), gear tooth (10) is connected with shift fork by this annular groove, the below of described gear tooth (10) is provided with the spring (11) abutted against with it.
Adopt above technological scheme, motor drives driving gear to rotate, and driving gear drives input gear to rotate by driven gear, and input gear drives pagoda tooth spiral to turn again; Gear tooth, under the effect of shift fork, can slide on spline spindle, engages selectively with certain fluted disc of pagoda tooth, makes the power of pagoda tooth pass to spline spindle by gear tooth, and spline spindle drives drilling rod to rotate.Gear tooth root, according to the difference of engagement object, has high speed gear and low speed gear, drilling rod can be made as required to carry out creeping into operation with different rotating speeds, with the usage requirement of satisfied different occasion, thus effectively improve the adaptive capacity of rig.Spring is for overcoming the weight of gear tooth, and to reduce gear tooth gravity to the impact of shift fork, under the action of the spring, the good reliability of gear tooth held by shift fork, the longer service life of shift fork.
For the ease of arranging, make more compact structure, better tightness, described driving gear (4) and driven gear (5) are all positioned at motor end cap (2), and at described motor end cap (2) top, sealing gland seat (12) is installed in the position of corresponding spline spindle (7) upper end.
The top of described spline spindle (7) is supported by bearing and clutch shaft bearing seat (13), and clutch shaft bearing seat (13) is positioned at casing (1), and fixes with the roof of casing (1); The lower end of spline spindle (7) is supported by bearing and the second bearing support (14), and the second bearing support (14) is positioned at the below of casing (1), and fixes with the bottom of casing (1).Above structure dismounting is convenient, and the good reliability of spline spindle supporting location, can guarantee that spline spindle rotates flexibly.
As preferably, described pagoda tooth (8) is made up of large, medium and small three fluted discs set gradually from top to bottom, and the gear tooth (10) matched with pagoda tooth (8) is up-small and down-big duplicate gear.
Beneficial effect: the utility model has top gear and bottom gear, enables the drilling rod of rig carry out creeping into operation with different rotating speeds, with the needs of satisfied different occasion, has the features such as modern design, structure is simple, good reliability, gear shift operation are convenient.
