Abstract
The utility model relates to a drum-shaped gear coupling, which can be particularly used for connecting two rotating shafts which are coaxial or parallel basically, can be used for occasions of frequently alternative rotation and counter rotation and frequency starting, and can be used for lifting, operating, revolving and variable amplitude mechanisms. The drum-shaped gear coupling comprises a brake wheel, an inner gear ring, an outer gear shaft sleeve and a cap. The brake wheel is arranged on a high-speed shaft of a speed reducer, the inner gear ring is tightly fixed with the brake wheel through a hinged bolt and meshed with drum-shaped teeth of the external gear shaft sleeve, and the cap is arranged on a sealing ring in the inner gear ring. The drum-shaped gear coupling is strong in bearing capacity and large in angle displacement compensation. Drum-shaped tooth surfaces improve contact conditions of inner teeth and outer teeth, thereby avoiding shortages of extruding of edges of straight teeth and stress concentration under conditions of angle displacement, simultaneously improving tooth surface friction and wear situations, reducing noise, and having high transmission efficiency and long maintenance period.
Description
Technical field
The utility model relates to coupling, and a kind of specifically drum gear coupling is used for connecting two coaxial lines and arranges or substantially parallel rotating shaft, can be used for the occasion that clockwise and anticlockwise is changeable, starting is frequent, hoists, moves, revolution and jib lubbing mechanism all can use.
Background technique
The coupling that hoist uses is mainly used to connect two coaxial lines and arranges or substantially parallel rotating shaft that transmitting torque compensates a few degrees and radial deflection simultaneously, can also improve the dynamic characteristic of transmission device sometimes.Half-coupling sometimes can the used as braking wheel.Reliable operation, bearing capacity is big.Possesses compensation performance.Compare transmitting torque maximum when measure-alike with the other types coupling.
Summary of the invention
The purpose of this utility model provides the coupling that a kind of bearing capacity is strong, the angular displacement compensation rate is big, has avoided straight-tooth increment seamed edge extruding under the angular displacement condition, and the drawback that stress is concentrated can reduce noise simultaneously, the transmission efficiency height, and service cycle is long.
The technological scheme that provides according to the utility model, drum gear coupling comprises Brake drum, ring gear, external tooth axle sleeve, Tong Gai, described Brake drum is contained on the speed reducer high speed shaft, ring gear and Brake drum are closely fixing by articulation bolt, the engagement of the drum type tooth of ring gear and external tooth axle sleeve, logical lid are contained on the seal ring in the ring gear.
Compared with the prior art the utility model has the following advantages:
1, bearing capacity is strong.Under identical internal tooth casing external diameter and coupling maximum outside diameter, the bearing capacity average specific spur gear coupling of rack barrel coupling improves 15～20%.
2, angular displacement compensation rate is big.When radial displacement equalled zero, the angular displacement allowable of spur gear coupling was 1o, and the angular displacement allowable of rack barrel coupling is 1o30 ', improved 50%.Under identical modulus, the number of teeth, the facewidth, crowned teeth is bigger than the angular displacement that straight-tooth allows.
3, drum-shaped tooth improves the contact conditions of inside and outside tooth, has avoided straight-tooth increment seamed edge extruding under the angular displacement condition, and the drawback that stress is concentrated has been improved gear tooth friction, wear condition simultaneously, has reduced noise, and service cycle is long.
4, external tooth axle sleeve increment flare shape makes inside and outside tooth mounting or dismounting very convenient.
5, transmission efficiency is up to 99.7%.It is higher to be suitable for revolution, frequently opens, brakes occasion.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Embodiment during following the utility model is incited somebody to action in conjunction with the accompanying drawings is further described:
As shown in Figure 1, drum gear coupling described in the utility model comprises: Brake drum 1, ring gear 2, external tooth axle sleeve 3, logically cover 4 etc.
The utility model adopts Brake drum 1 to be contained on the speed reducer high speed shaft, and ring gear 2 and Brake drum 1 are closely fixing by articulation bolt, the drum type tooth engagement of internal tooth Fig. 2 and external tooth axle sleeve 3, the logical lid on 4 seal rings that are contained in the ring gear 3.
The utility model working principle and working procedure:
When motor starting, the output shaft of motor just drives external tooth axle sleeve 3 and rotates together.Ring gear 2 meshes together with the drum type tooth of external tooth axle sleeve 3, then ring gear 2 just and external tooth axle sleeve 3 rotate synchronously.Ring gear 2 and Brake drum 1 are closely united by several high-intensity articulation bolts, and under the drive of ring gear 2, Brake drum 1 just rotates.Because Brake drum 1 is to be contained on the speed reducer high speed shaft, so speed reducer just begins action under the drive of Brake drum 1.Logical to cover 4 mainly be to be used for blocking the seal ring that is contained in the ring gear 3, thereby by drum gear coupling motor and speed reducer are moved together.
Claims (2)
1. drum gear coupling, comprise Brake drum (1), ring gear (2), external tooth axle sleeve (3), logical lid (4), it is characterized in that: Brake drum (1) is contained on the speed reducer high speed shaft, and ring gear (2) and Brake drum (1) are closely fixing by bolt, the drum type tooth engagement of ring gear (2) and external tooth axle sleeve (3), logical lid (4) are contained on the seal ring in the ring gear (3).
2. drum gear coupling according to claim 1 is characterized in that, described external tooth axle sleeve (3) increment flare shape.
