A hollow shaft is arranged inside the cylindrical gear speed reducer through a bearing A and a bearing B. Large gears are respectively arranged at two sides of the hollow shaft and connected with the hollow shaft through a spline. Gear shafts are respectively arranged inside the reducer at one side of the large gears through a bearing C and meshed with the large gears. The speed reducer for the screw pile power head is compact in structure, small in size, large in transmission ratio, intensive in classification, high in efficiency, stable in operation, small in noise, convenient to disassemble and repair, capable of solving the problems that a three-ring speed reducer is large in size, high in assembling technique, large in vibration of a transmission mechanism and high in noise, and is particularly suitable for assembling and usage of a screw pile power head.
Description
Technical field
The utility model relates to a kind of retarder, is specifically related to a kind of retarder for the screw pile machine unit head.
Background technique
Screw pile machine unit head coupling is three-ring gear reducer at present.Also exist in actual use following defective:
(1) three-ring gear reducer is comprised of with four-bar linkage structure engagement in the few teeth difference, in order to avoid the dead point of quadratic crank mechanism, adopted three covers to differ the combination of engagement and four connecting rods in 120 the few teeth difference, three internal gear ring plate are arranged, owing to increased four-bar linkage structure, its structure is complicated more than general speed reducer.Increased the assembly technology difficulty, therefore must satisfy certain assembly condition and just can assemble up; Also increased simultaneously the accuracy Design restrictive condition.
(2) vibration of driving mechanism is large, noise is high, and along with the rotating speed of driving mechanism improves and increases.
(3) distance between speed reducer two crankshafts is subjected to the restriction of structure, must be greater than the root diameter of internal gear and two times of eccentric shafts apart from sum.Like this will be so that the boundary dimension of speed reducer be huger, and be difficult to dwindle.
Summary of the invention
The purpose of this utility model is: provide a kind of compact structure, volume little, velocity ratio is large, classification is intensive, efficient is high, and operate steadily, noise is little, easy for assembly, disassembly and maintenance, large to solve existing three-ring gear reducer volume, assembly technology requires high, and the vibration of driving mechanism is large, the retarder that is used for the screw pile machine unit head of the high problem of noise.
The technical solution of the utility model is:
A kind of retarder for the screw pile machine unit head, it is made of planet-gear speed reducer A, planet-gear speed reducer B and cylindrical gear reducer, it is characterized in that: by the bolt symmetry shape planet-gear speed reducer A and planet-gear speed reducer B are installed on the body at cylindrical gear reducer two ends, be provided with hollow shaft by bearing A and bearing B in the body of cylindrical gear reducer, be respectively arranged with gearwheel in the body of hollow shaft both sides, gearwheel is connected with hollow shaft by spline; Be provided with gear shaft by bearing C respectively in the body of gearwheel one side, gear shaft and gearwheel are connected with a joggle; Be respectively arranged with one-level planetary mechanism and secondary planet mechanism in the housing of described planet-gear speed reducer A and planet-gear speed reducer B, planet wheel on 1 grade of sun gear of one-level planetary mechanism and the 1 grade of planet carrier is connected with a joggle, the one-level planetary mechanism is connected with 2 grades of sun gears of secondary planet mechanism by 1 grade of planet carrier, and secondary planet mechanism is connected with gear shaft by 2 grades of planet carriers.
The utility model compared with prior art advantage be:
1, simple in structure, compact transmitting torque is large, and assembling is simple.
2, the high smooth running of efficient impacts littlely, and impulsive load is large, reliability is high, and noise is low.
3, planet part speed ratio can change flexibly, and the cylindrical gears volume of bottom can be adjusted size by the speed ratio of planet part, and flexible structure is changeable.
4. planetary speed reducer and cylindrical gear reducer are two independently unit, separately sealing, separately fuel feeding.Good sealing effect, power loss is few, and temperature rise is low.
5. output hollow shaft adopts an end to fix, and an end float support bears the very big axial force of drilling rod and the radial force of gear.
