Abstract
The utility model discloses a crown gear coupling, which comprises outer gear shaft sleeves at the drive end and the driven end. The outer gear shaft sleeves at the drive end and the driven end are connected with an inner gear ring through gear form, and two ends of the inner gear ring are provided with end caps. Sealing rings are respectively arranged among the end caps, the outer gear shaft sleeves and the inner gear ring. The split type end caps are integrally formed by end cap connecting bolts in connection. The outer gear shaft sleeves are in splined connection with shafts. The crown gear coupling transmits torque through the gear form, enables the gear form to fully play the role of transmitting large torque, with larger and more reliable torque and longer service life, and is adaptable to occasions of transmitting large torque.
Description
Technical field
The utility model relates to a kind of coupling, is specifically related to a kind of drum-shaped tooth type shaft coupling.
Background technique
The structure of JB/T8854.2-1999G II CL type drum-shaped tooth type shaft coupling as shown in Figure 1, master and slave moved end has a secondary external tooth axle sleeve 1 and a ring gear respectively, connects two ring gear flanges 2 by articulation bolt 3, and master and slave moved end is fused.Though the drum-shaped tooth type shaft coupling of this structure adopts profile of tooth to cooperate, and fails to utilize the profile of tooth transmitting torque, but by articulation bolt 3 transmitting torques, articulation bolt 3 easily produced distortion when moment of torsion was excessive, even damaged, and working life is also shorter.Since need on ring gear flange 2, articulation hole be set, the drum-shaped tooth type shaft coupling processed complex of this structure, and part is many, the cost height.
The model utility content
The technical problems to be solved in the utility model provides a kind of drum-shaped tooth type shaft coupling, and it can transmit more high pulling torque.
For solving the problems of the technologies described above, the technical solution of the utility model drum-shaped tooth type shaft coupling is:
The external tooth axle sleeve that comprises master and slave moved end, the external tooth axle sleeve of described master and slave moved end is connected with ring gear by profile of tooth; The ring gear two ends are provided with end cap.
Be respectively arranged with seal ring between described end cap and external tooth axle sleeve, the ring gear.
Described end cap is a split type, connects as one by the end cap connecting bolt.
Be connected for spline between described external tooth axle sleeve and the axle.
The technique effect that the utility model can reach is:
The utility model passes through the profile of tooth transmitting torque, but has given full play to the effect of profile of tooth transmitting large torque, and transmitting torque is bigger more reliable, and longer service life is applicable to the occasion of transmitting large torque.
The utility model is compared with the standard coupling, can transmit more high pulling torque under same tooth profile parameter situation, so the comparable standard coupling is little No. one during type selecting.
The utility model adopts a ring gear to connect the external tooth axle sleeve of master and slave moved end, and part is few, need not to process the articulation bolt hole, makes simple.
The utility model is determined transmitting torque main parameters such as profile of tooth modulus, the facewidth, tooth pitch with reference to JB/T8854.2-1999G II CL type drum-shaped tooth type shaft coupling, and therefore having generality has specificity concurrently.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
Fig. 1 is the structural representation of standard drum-shaped tooth type shaft coupling;
Fig. 2 is the structural representation of the utility model drum-shaped tooth type shaft coupling.
Among the figure, 1 external tooth axle sleeve, 2 ring gear flanges, 3 articulation bolts, 10,11 external tooth axle sleeves, 12 ring gears, 13 end caps, 14 seal rings, 15 end cap connecting bolts.
Embodiment
As shown in Figure 2, the utility model drum-shaped tooth type shaft coupling comprises external tooth axle sleeve 11, ring gear 12, end cap 13, seal ring 14, the end cap connecting bolt 15 of master and slave moved end.Ring gear 12 connects the external tooth axle sleeve 11 of master and slave moved end by profile of tooth; Ring gear 12 two ends are provided with end cap 13, and end cap 13 makes ring gear 12 in axially locating.
Ring gear 12 is provided with the oil circuit that leads to profile of tooth, but oil lubrication is carried out in oiling.
Adopt spline to be connected between external tooth axle sleeve 11 and the axle, and connect without flat key, thus the needs of adaptation transmitting large torque.
Be respectively arranged with seal ring 14 between end cap 13 and external tooth axle sleeve 11, the ring gear 12, adopt felt ring seal, good seal performance can be used for the many environment of dust.
End cap 13 is a split type, connects as one by end cap connecting bolt 15, and end cap connecting bolt 15 adopts lock nut.
External tooth axle sleeve 11 with master and slave moved end during use is enclosed within respectively on the master and slave moving axis 10, connects master and slave moving axis 10.
