Abstract
A tooth type shaft coupling easy to disassemble relates to the single engagement tooth type shaft coupling of the flexible shaft coupling, belonging to the shaft coupling technique field, which is used in resolving the question that the disassembly is not convenient during the maintenance, comprising a left, a right back-rest wheel and a counter shaft, the outer gear wheel of the counter shaft is engaged with the inner gear wheel of one back-rest wheel, the left and the right back-rest wheels are connected via the screw bolt, which is improved that an end face key is arranged between the left and the right back-rest wheels, the end face key is positioned in the key box of the left and the right back-rest wheels connection end face, a gap is allowed between the screw bolt and the bolt hole. The left and the right back-rest wheels of the utility model transfer dynamic torque via the end face key, thereby a larger gap is allowed between the screw bolt and the bolt hole, thereby convenient for the disassembly of the shaft coupling during the equipment maintenance, eliminating the obstacle that disassembly is difficult during the equipment rush repair and maintenance, and correspondingly lowering the maintenance labor intensity, which is applicable to used in the larger power equipments and the place of narrow installation space.
Description
Technical field
The utility model relates to the single engagement gear coupling in the flexible coupling, belongs to the coupling technical field.
Background technique
Single engagement gear coupling is made up of left and right clutch and jack shaft etc., internal gear in external gear on the jack shaft and the clutch is meshed, two transmissions are connected with another clutch with jack shaft respectively, allow the displacement within the specific limits of two transmission shafts, left and right clutch ties mutually by spiral shell and connects, and has very high bearing capacity.Because by connecting bolt transferring power moment of torsion, so the bolt hole on bolt and the clutch need be connected, bolt hole generally passes through the reamer articulation between the left and right clutch, with the reliable contact of assurance and bolt be connected.The coupling of this kind structural type in use, particularly in use than rugged environment, bolt and bolt hole are easy to closely cement in together, its dismounting when overhaul of the equipments is become to bother very much, particularly big in the coupler structure size, the diameter of bolt is big and space, mounting point when narrow and small, its dismounting is difficulty especially, when equipment breaks down, often therefore incur loss through delay the troubleshooting of faults processing time, and increased considerably maintenance load and labor intensity, so the above-mentioned coupling of reply improves.
Summary of the invention
Technical problem to be solved in the utility model is to dismantle in the easy access under the prerequisite that keeps single engagement gear coupling service behaviour.
The alleged problem of the utility model realizes with following technical solution:
A kind of easy-to-dismount gear coupling, left and right clutch and jack shaft are arranged in the formation, internal gear in external gear on the jack shaft and the clutch is meshed, left and right clutch connects by bolt, its improvement is, set up straight end-face key 4 between the described left and right clutch, straight end-face key 4 is arranged in the keyway 5 on the left and right clutch connection end face, leaves the space between described bolt and the bolt hole.
Above-mentioned easy-to-dismount gear coupling, the space between described bolt and the bolt hole are 1～2MM.
The utility model is after setting up straight end-face key between the left and right clutch, left and right clutch can pass through straight end-face key transferring power moment of torsion, so allow to keep between bolt and the bolt hole bigger gap, thereby made things convenient for the dismounting of coupling in the overhaul of the equipments, the obstacle of dismounting difficulty when having eliminated the repairing repair apparatus, and the corresponding maintenance labor intensity that reduced, suit using than powerful device and the narrow and small place of installing space.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is that left and right clutch connects end view.
Embodiment
Consult accompanying drawing, be illustrated as the concrete application example on steel rolling mill's straightening machine floating axle.1,2 is left and right clutch among the figure, 3 is jack shaft, is respectively equipped with keyway 5 on the connection end face of left and right clutch, and straight end-face key 4 is embedded in the involutory keyway 5, the thickness of the involutory width 〉=straight end-face key 4 of two keyways 5 is to avoid hindering being in contact with one another of left and right clutch.The concrete structure size of straight end-face key and keyway and quality of fit etc. are looked size of transmitted power, moment of torsion and coupling etc. and are chosen.Bolt between the left and right clutch is owing to the task of no longer bearing transmitting torque, thus the corresponding increase of the diameter of bolt hole 6, and maintain enough spaces between the bolt, can be behind the nut of removing on the bolt easily with under the Bolt dismantling.Pore volume is 1～2MM, the corresponding increase of bolt hole when the diameter of bolt increases.
Claims (2)
