Description
Technical field
The utility model relates to shaft coupling field, particularly relates to a kind of crown gear coupling.
Background technology
In steel mill's continuous rolling production line, often relate to step-down gear and the milling train of multiple model, therefore production line generally has the shaft coupling of several specification, shaft coupling adopts bulging type tooth-like usually, such as specification is �� 140 �� �� 180, �� 150 �� �� 180, ��, 152 �� �� 180, the multiple sizes such as �� 160 �� �� 180, �� 180 �� �� 180; Wherein two sizes in often kind of specification are respectively step-down gear end shaft hole diameter �� motor side shaft hole diameter. Existing crown gear coupling mainly has the following disadvantages: 1, specifications and models are not unified, and spare part is corresponding will be increased, and occupies inventory finance big; 2, specifications and models are not unified, and spare part interchangeability is poor, inefficiency; 3, the easy broken parts of shaft coupling is mainly gear ring, but it accounts for the 1/4-1/3 of shaft coupling total quality, and existing shaft coupling often needs integral replacing after damaging, and the shaft coupling under changing is abandoned with steel scrap form, causes cost to increase.
Practical novel content
The technical problem that the utility model solves is to provide a kind of solving the problem, and can save shaft coupling and change cost, and improve shaft coupling matching efficiency, reduce spare part quantity, cost-saving crown gear coupling.
The utility model solves the technical scheme that its technical problem adopts: crown gear coupling, comprises two in the symmetrically arranged externality shaft of mirror image, is provided with circumferentially protruding gear ring on the end that two externality shafts are close; Also comprising internal tooth hoop circle, described internal tooth hoop circle is set on the gear ring of two externality shafts simultaneously, and described externality shaft is made up of the axle sleeve coaxially arranged and external tooth cover, and described gear ring is arranged on external tooth cover, and described external tooth cover is dismountable to be set on axle sleeve.
Further: the keyway being respectively arranged with mutual coupling on the inwall of external tooth cover and on the outer wall of axle sleeve, is provided with key in the keyway after external tooth cover and axle sleeve mate mutually, and described external tooth cover is connected by key with axle sleeve.
Further: described key is provided with at least one group, often group comprises two keys symmetrical in mirror image.
Further: two keys axially the distributing in "eight" shape at externality shaft being arranged in same group.
Further: the angle theta of two the key distributions being arranged in same group is 120 ��.
Further: the V-shaped otch of cross section of the keyway arranged on the inwall of external tooth cover and on the outer wall of axle sleeve.
Further: the V-notch on external tooth cover and axle sleeve is rectangular after cooperatively interacting.
Further: limit place straight line in described rectangle and the axes intersect of externality shaft.
The beneficial effects of the utility model are: by being made up of the axle sleeve coaxially arranged and external tooth cover by externality shaft, like this when the gear ring part on external tooth cover is damaged, it is only necessary to changing external tooth cover part, axle sleeve part then can reuse, cost-saving. Simultaneously, by coordinating the axle sleeve of different size and external tooth cover, the adaptive effect of shaft coupling can be improved, identical external tooth cover is adopted to coordinate from different axle sleeves, can form can the externality shaft of adaptive various step-down gear and milling train, therefore can greatly reduce spare part quantity, reduce stock's occupied fund situation. In addition, by adopting key in groups axle sleeve and external tooth cover to be connected, and preferably adopt two keys of the distribution in "eight" shape to connect, transmission of torque effect can be improved.

Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is illustrated further.
Shown in as shown in Figure 1 to Figure 4, crown gear coupling described in the utility model, comprises two in the symmetrically arranged externality shaft 1 of mirror image, is provided with circumferentially protruding gear ring 11 on the end that two externality shafts 1 are close; Also comprise internal tooth hoop circle 6, described internal tooth hoop circle 6 is set on the gear ring 11 of two externality shafts 1 simultaneously, described externality shaft 1 is made up of the axle sleeve 2 coaxially arranged and external tooth cover 3, and described gear ring 11 is arranged on external tooth cover 3, and described external tooth cover 3 is dismountable to be set on axle sleeve 2.
Wherein, by externality shaft 1 is made up of the axle sleeve 2 coaxially arranged and external tooth cover 3, like this, after the gear ring 11 on external tooth cover 3 damages, it is only necessary to change external tooth cover 3, and axle sleeve 2 part is reusable, reaches cost-saving object.
In addition, also by different axle sleeves 2 and external tooth cover 3 being combined, obtain the coupler structure of different size, the step-down gear different with correspondence or the cooperation of milling train. Such as, adopting identical external tooth cover 3, correspondence coordinates from the axle sleeve 2 of different shaft hole diameter respectively, and the externality shaft 1 that can obtain different size is overall, and then can meet the requirement of different step-down gear or milling train specification.
In addition, installation relation between axle sleeve 2 and external tooth cover 3 should meet the two and can transmit torque; Namely must not relatively rotate after installing. Installing in order to convenient, as shown in drawings, be respectively arranged with the keyway 4 of mutual pairing, be provided with key 5 in the keyway 4 after external tooth cover 3 and axle sleeve 2 mate mutually on the inwall of external tooth cover 3 and on the outer wall of axle sleeve 2, described external tooth cover 3 is connected by key 5 with axle sleeve 2.
More specifically, it is contemplated that there is situation about rotating and reverse to externality shaft 1, key 5 can be pressed group and arrange, and arrange at least one group, and often group comprises two is the symmetrical keys 5 of mirror image. Certainly, it should corresponding keyway 4 structure is set on axle sleeve 2 and external tooth cover 3.
In addition, under regular situation, rectangular groove structure is arranged to by keyway 4, and is also offer rectangular groove structure accordingly on axle sleeve 2 and external tooth cover 3, but after this kind of keyway arrangements coordinates with key 5, its effect transmitting torque is poor. For this reason, the utility model provides following preferred structure further: the V-shaped otch 41 of cross section of the keyway 4 arranged on the inwall of external tooth cover 3 and on the outer wall of axle sleeve 2; Further, after being cooperatively interacted by the V-notch 41 on external tooth cover 3 and axle sleeve 2 rectangular. Insert key 5 in the rectangular tank complemented each other to form by two V-notch 41, and the two ends of key 5 like this contacts with axle sleeve 2 is corresponding with external tooth cover 3 respectively, and when key the 5 of identical size, its effect transmitting torque is better than adopting conventional rectangular tank. Further, two limits that V-notch 41 is formed at external tooth cover 3 and axle sleeve 2, wherein one is longer than another; Both referred to that V-notch 41 was for unsymmetric structure; Like this, a structure being rectangle can be formed by two shape otch 41, be more conducive to the transmission of torque. As shown in Figure 2, further can by the axes intersect of the limit place straight line in described rectangle and externality shaft 1; Transmission of torque effect can be improved.
In addition, when above-mentioned be set to one group of key 5 to comprise two in mirror image symmetrical key 5, two keys 5 being preferably placed in same group further are in the axially distribution in "eight" shape of externality shaft 1, and concrete shape can refer to structure shown in Fig. 2. More specifically, the angle theta that can be distributed by two keys 5 that be arranged in same group is 120 ��.
