Abstract
A planetary winder relates to a planetary winder used on tower crane in the field of construction engineering mashinery, which comprises a framework, a drum arranged on the framework, a speed reducer connected with the framework and a motor connected with the speed reducer. The utility model is characterized in that: the speed reducer comprises a case fixed on end face of the framework near the motor and two-level planetary gear transmission device comprising two basic planetary gear transmission units arranged inside the case. The motor and the speed reducer are connected together via a splined sleeve connecting the motor output shaft and the input shaft of the speed reducer. The drum is connected with the output shaft of the speed reducer by a coupling flange. The other end of the drum is mounted on the framework by a revolving shaft fixed on the end face of the drum. The utility model has the advantages of simple structure, simple production process, convenient maintenance, low using cost and low production cost, which can replace the present similar products.
Description
Technical field
The utility model relates to a kind of tower crane planetary transmission winch, belongs to the constructional engineering machinery technical field.
Background technology
The planetary transmission winch that present tower crane is used drives transmission shaft component 3 by the motor 1 that is fixed on the frame 2 as shown in Figure 1, slows down by retarder 4, drive reels 5 rotations by retarder 4 again, thereby the realization steel rope is reeled on reel and put rope.The shortcoming one of this winch is that its transmission shaft component is an elongate articles, and component parts is many, need transmission shaft component is done experiment of dynamic balancing, and complex process, element precision requires high; The 2nd, its, the secondary planet frame 6 of retarder 4 is fixed on that end away from motor of frame by the flange 7 of wounded in the battle key, the casing 8 of retarder is fixed on round going up with reel 5 runnings in the reel, rotor inertia is big, guarantee that mechanical operation is steadily then all very high to the requirement of the working accuracy of the rigidity of frame and frame, reel.In addition, the retarder that is contained in the reel 5 need be taken entire mechanism apart when overhauling, and maintenance is inconvenient, and spended time is long.The 3rd, the dead axle transmission mechanism 10 that its retarder is NGW by a differential planet gear transmission 9 and classification designator forms the closed planetary transmission, low, the complex structure of driving efficiency, and each rotating part stack-mounted right alignment is required height, and parts processing request height causes the manufacturing cost height.
The utility model content
The purpose of this utility model is the above-mentioned shortcoming that overcomes prior art, for tower crane provides a kind of running steady, and the planetary transmission winch of driving efficiency height, simple in structure, low cost of manufacture.
The formation of this planet transmission winch comprises frame, rack-mounted reel, with frame bonded assembly retarder, with retarder bonded assembly motor, it is characterized in that described retarder is made of casing on the end face of the close motor side that is fixed in frame and the twin-stage planetary gear mechanism of being made up of two basic epicyclic gear transmission groups that is installed in the casing, described motor and retarder are socketed in motor shaft with one and are connected with spline housing on the reducer input shaft, described reel is connected with the output shaft of retarder with a tie-plate, and the other end of reel is installed on the frame with a S. A. that is fixed on the reel end face.
Motor shaft is directly passed to retarder by spline housing with motion during work, and spline housing length is short, and the two ends spline is that broaching tool is once pulled out, and right alignment is good, need not do experiment of dynamic balancing, and technology is simple, low cost of manufacture.Drive tie-plate by reducer output shaft and rotate and then drive the reel running.Compare with the mode of operation that reel turns round with original whole retarder, its rotor inertia reduces greatly, and the mechanical operation stationarity improves greatly.Retarder changes the twin-stage planetary gear mechanism of being made up of two basic epicyclic gear transmissiones serves as, and structure is more compact, and the driving efficiency height is lower than prior art to the part Geometrical Tolerance Principle, makes part qualification rate height, low cost of manufacture.Retarder is fixed on the end face of close motor side of frame, and drive path is short, and can overhaul retarder separately under the situation of not unreel tube and frame during maintenance, also can pull down the retarder integral replacing, and maintenance is convenient, takes a short time.
Compare with existing like product, the utility model has the advantages that simple in structurely, make easily, complete machine once assembles qualification rate can reach 99%; The mechanical operation stationarity improves greatly, and maintenance is convenient, greatly reduces and uses and manufacturing cost.Alternative existing like product uses.
Provide embodiment of the present utility model below in conjunction with accompanying drawing.
Description of drawings
Fig. 1 is the structural representation of existing planetary transmission winch.
Fig. 2 is a structural representation of the present utility model.
The specific embodiment
Referring to Fig. 2, the formation of this planet transmission winch comprises frame 11, be installed in the reel 12 on the frame 11, with frame bonded assembly retarder 13, with retarder bonded assembly motor 14, described retarder 13 by the casing on the end face of the close motor side that is fixed in frame 11 15 and be installed in the casing 15 by two basic epicyclic gear transmission groups 16, the 17 twin-stage planetary gear mechanisms of forming constitute, described motor and retarder are socketed in motor shaft 18 with one and are connected with spline housing 20 on the reducer input shaft 19, described reel is connected with the output shaft 22 of retarder with a tie-plate 21, and the other end of reel is installed on the frame 11 with a S. A. 23 that is fixed on the reel end face.Motor shaft 18 drives reducer input shaft 19 by spline housing 20 during work, drives reducer output shaft 22 and tie-plate 21 rotations after two basic epicyclic gear transmission groups 16,17 are slowed down, and then drives reel 12 runnings.
