Abstract
The utility model relates to a combined type transmission structure of a heavy lift, comprising a brake wheel and a shaft joint; the transmission structure is characterized in that: the brake wheel and the shaft joint are connected with a turntable shaft, and are located and mounted by a spigot and a bolt; the shaft joint adopts a full-depth gear shaft joint. The transmission structure has simple structure, the volume is small, and the working load of mounting and dismounting is reduced; the transmission structure has the advantages that the transmission torque is high and the manufacturing cost is reduced and the like.
Description
Technical field
The utility model belongs to the goliath complete equipment and makes the field, particularly relates to a kind of goliath compound propulsion structure.
Background technology
The transmission of moment realizes by transmission shaft and coupler between motor in the hoisting crane complete equipment and the brake wheel, general major axis and the half gear coupler of adopting makes up in the existing hoisting crane complete equipment, this major axis structure can be occupied certain space in hoisting crane, make that the volume of hoisting crane equipment package is big, especially in hoister in large tonnage equipment; Adopt half gear coupler to have in addition to adjust angle little, the error that can not actv. reduces processing or produced when installing makes reduce the service life of hoisting crane, and half gear coupler can not use separately, so greatly improved productive costs.
Summary of the invention
The utility model for solve the technical matters that exists in the known technology provide a kind of simple in structure, transfer torque big and reduce the goliath compound propulsion structure of hoisting crane volume.
The technical scheme that the utility model is taked for the technical matters that exists in the solution known technology is:
A kind of goliath compound propulsion structure comprises: brake wheel, coupler is characterized in that: described brake wheel is connected by turntable shaft with coupler, and described coupler adopts the full-depth tooth gear coupling.
The utility model can also adopt following technical measures:
Be shaped on boss on the rotating disk end face of described turntable shaft, the seam that this boss and brake wheel end face are shaped on is equipped, and the rotating disk of turntable shaft installs by fastener and brake wheel, and the prolongation axle of described turntable shaft is connected with coupler by key.
The advantage that the utlity model has with good effect is: because the utility model is connected with coupler brake wheel by turntable shaft, by the seam location and installation, easy installation and reliable and shortened distance between drg and the coupler greatly, reduced the volume of hoisting crane; Coupler adopts the full-depth tooth gear coupling in addition, the error that produces in the time of can adjusting part and install.Therefore said structure is simple, transfer torque is big, volume is little, and has reduced productive costs.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1, brake wheel; 1-1, seam; 2, turntable shaft; 2-1, rotating disk; 2-2, prolongation axle; 2-3, boss; 3, bolt; 4, coupler; 5, key.
The specific embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1, brake wheel 1 is connected by turntable shaft 2 with coupler 4, is shaped on boss 2-3 on the rotating disk 2-1 end face of this turntable shaft 2, and the seam 1-1 that this boss 2-3 and brake wheel 1 end face are shaped on is equipped, and is reliable and convenient by the seam location; For ease of removing and installing, the rotating disk 2-1 of turntable shaft 2 is fastening by fastener bolt 3 and brake wheel 1, and the prolongation axle 2-2 of its turntable shaft 2 is connected with coupler 4 by key 5.Described coupler 4 adopts the full-depth tooth gear coupling, adjusts the error that produces when part is installed again.Therefore said structure is simple, transfer torque is big, volume is little, and has reduced productive costs.
