Abstract
The invention discloses an internal and external drum tooth connection structure for cranes. The internal and external drum tooth connection structure comprises an internal ring gear, an external gear shaft sleeve, an end cap, a retaining plate, a pin and an elbow. The external gear shaft sleeve sleeves a high-speed shaft of a reducer, the internal ring gear is fixedly connected to a drum through the pin, crowned teeth are arranged outside the external gear shaft sleeve and are meshed with the internal ring gear, the retaining plate is arranged at the inner end of the internal ring gear, a sealing ring is arranged between the retaining plate and the external gear shaft sleeve, an oil circuit is arranged on the internal ring gear, the elbow is mounted on the internal ring gear through the end cap and is communicated with the oil circuit, and a nozzle is arranged on the elbow. By the adoption of the crowned-tooth structure, the internal and external drum tooth connection structure is high in bearing capacity, large in angular displacement compensation amount, improved in tooth surface friction and wear condition, lower in noise, high in transmission efficiency and long in maintenance circle; the gear end of the external gear sleeve is flared in shaped, so that mounting and dismounting of internal and external teeth are facilitated.
Description
Technical field
The present invention relates to a kind of hoist roller, relate in particular to a kind of for external tooth connection structure in the reel of hoisting crane.
Background technology
The interior external tooth connection structure of hoist roller is mainly used to connect hoist roller and reductor, transmitting torque.Compensate a few degrees and radial runout simultaneously, sometimes can also improve the dynamic characteristics of driving device.
At present traditional in the reel of hoisting crane, external tooth connection structure ubiquity load-carrying capacity is poor, angular transposition compensation rate is little, under angular transposition condition, increment seamed edge extrusion stress is concentrated, the large and low shortcoming of driving efficiency of noise.
Summary of the invention
The object of the present invention is to provide a kind of for external tooth connection structure in the reel of hoisting crane, it has the advantages that load-carrying capacity is good, angular transposition compensation rate is large, noise is low and driving efficiency is high, to solve in prior art the problems referred to above for external tooth connection structure exists in the reel of hoisting crane.
For reaching this object, the present invention by the following technical solutions:
A kind of for external tooth connection structure in the reel of hoisting crane, it comprises internally toothed annulus, externality shaft, end cap, baffle plate, pin and elbow, wherein, described externality shaft is installed on the high speed shaft of reductor, described internally toothed annulus is fixedly connected on reel by pin, described externality shaft is outside equipped with crowned teeth, described crowned teeth is meshed with the tooth of described internally toothed annulus, described baffle plate be arranged at the inner of internally toothed annulus and and externality shaft between be provided with seal ring, in described internally toothed annulus, oil circuit is set, described elbow is installed on internally toothed annulus and with described oil circuit and is connected by end cap, and be provided with oil nozzle on described elbow.
Especially, one end of described externality shaft is provided with pressing plate by bolt and spring washer circle.
Especially, the increment flare of described externality shaft.
Especially, between described end cap and described externality shaft, be provided with felt collar oil sealing.
Especially, described oil nozzle adopts clasp joint formula oil nozzle.
Beneficial effect of the present invention is that compared with prior art described for external tooth connection structure employing crowned teeth structure in the reel of hoisting crane, load-carrying capacity is strong, angular transposition compensation rate is large, has improved gear tooth friction, wear condition simultaneously, has reduced noise, driving efficiency is high, and maintenance cycle is long.External tooth cover increment flare shape, makes inside and outside tooth mounting or dismounting very convenient.
Brief description of the drawings
Fig. 1 is the structural representation for external tooth connection structure in the reel of hoisting crane that the specific embodiment of the invention 1 provides.
In figure:
1, internally toothed annulus; 2, externality shaft; 3, end cap; 4, baffle plate; 5, pin; 6, elbow; 7, reel; 8, seal ring; 9, oil circuit; 10, clasp joint formula oil nozzle; 11, felt collar oil sealing; 12, bolt; 13, spring washer; 14, pressing plate.
Detailed description of the invention
Further illustrate technical scheme of the present invention below in conjunction with accompanying drawing and by detailed description of the invention.
Refer to shown in Fig. 1, Fig. 1 is the structural representation for external tooth connection structure in the reel of hoisting crane that the specific embodiment of the invention 1 provides.
In the present embodiment, a kind ofly comprise internally toothed annulus 1, externality shaft 2, end cap 3, baffle plate 4, pin 5 and elbow 6 for external tooth connection structure in the reel of hoisting crane, described externality shaft 2 is installed on the high speed shaft of reductor, described internally toothed annulus 1 is fixedly connected on reel 7 by pin 5, described externality shaft 2 is outside equipped with crowned teeth, described crowned teeth is meshed with the tooth of described internally toothed annulus 1, and the increment flare of described externality shaft 2.Described baffle plate 4 be arranged at the inner of internally toothed annulus 1 and and externality shaft 2 between be provided with seal ring 8, the interior oil circuit 9 that arranges of described internally toothed annulus 1, described elbow 6 is installed on internally toothed annulus 1 and with described oil circuit 9 and is connected by end cap 3, and on described elbow 6, is provided with clasp joint formula oil nozzle 10.
Between described end cap 3 and described externality shaft 2, be provided with felt collar oil sealing 11, one end of described externality shaft 2 is provided with pressing plate 14 by bolt 12 and spring washer 13.
In the time of motor starting, drive externality shaft 2 to rotate, because internally toothed annulus 1 and the drum type tooth of externality shaft 2 mesh together, so internally toothed annulus 1 just and externality shaft 2 synchronously rotate.Drive lower mandrel member 7 at internally toothed annulus 1 just rotates.Because externality shaft 2 is to be contained on the high speed shaft of reductor, so reductor just starts action.
Above embodiment has just set forth groundwork of the present invention and characteristic; the present invention is not limited by above-mentioned example; without departing from the spirit and scope of the present invention, the present invention also has various variations and change, and these variations and change all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
