Abstract
The utility model discloses a nut-taper fit locked expansion sleeve which comprises an inner taper sleeve (1), an outer taper sleeve (2) and a round nut (4); the inner taper sleeve (1) is sheathed on a transmission shaft (8); the outer taper sleeve (2) is sheathed on the inner taper sleeve (1) and forms a fit conical surface (6) with the inner taper sleeve (1); a hub (7) is sheathed on the outer taper sleeve (2); an expansion gap A(9) and an expansion gap B (10) are respectively arranged on the inner taper sleeve (1) and the outer taper sleeve (2); a thread (5) is arranged at one end outside the inner taper sleeve (1); the round nut (4) is fit and connected with the inner taper sleeve (1) through the thread (5); and a retaining washer (3) is sandwiched between the round nut (4) and the hub (7). The nut-taper fit locked expansion sleeve has the beneficial effects of simple structure, convenient operation, time and labor saving, no damage on the mechanical strength of parts, no stress concentration, high installation precision and reliable transmission performance.
Description
Technical field
The utility model mechanical technology, particularly a kind of expansion set by nut and taper fit locking.
Background technique
In mechanical transmission, axle is to be fixed together by key with the wheel that is enclosed within on the axle, realizes the purpose of transmitting movement moment of torsion.The key ways of connecting is simple in structure, can wheel be fixedly linked in axle well and go up and together rotate with axle, but traditional mode also must set out keyway on the wheel hub of axle and wheel; Not only weakened the mechanical strength of axle and wheel hub; And can produce stress at the position that axle and wheel hub are offered keyway and concentrate, crackle, crack even opening appear easily at the keyway place of axle or wheel hub, can directly cause mechanical failure; Have a strong impact on the proper functioning life-span of machine, maintenance cost is high.In addition, the key Placement is also become flexible than being easier to occur connecting, and influences transmission accuracy, so need often to change key, carries out but the key Placement mostly is the mode that adopts manpower to beat bump when the installation or removal wheel, wastes time and energy ten minutes inconvenience.
The model utility content
The purpose of the utility model is to overcome the shortcoming of existing technology, and a kind of expansion set by nut and taper fit locking is provided, and it is simple in structure, and is easy to operate, time saving and energy saving, the mechanical strength of harmless part itself, and unstressed concentrating, installation precision is high.
The purpose of the utility model realizes through following technological scheme:
A kind of expansion set by nut and taper fit locking, it comprises inner conical drogue, external conical sleeve and round nut, inner conical drogue is enclosed within on the transmission shaft; External conical sleeve is enclosed within on the inner conical drogue, and cooperates the conical surface, wheel hub to be enclosed within on the external conical sleeve with inner conical drogue formation; Be respectively equipped with swelling seam A and swelling seam B on inner conical drogue and the external conical sleeve; The inner conical drogue outside one end is provided with screw thread, and round nut is connected through screw thread and inner conical drogue, accompanies floor clip between round nut and the wheel hub.
The utlity model has following advantage: simple in structure, easy to operate, time saving and energy saving, the mechanical strength of harmless part itself, unstressed concentrating, installation precision is high, and transmission performance is reliable.
Description of drawings
Fig. 1 is the structural representation of the utility model,
Fig. 2 is the A-A view of Fig. 1.
Among the figure, the 1-inner conical drogue, the 2-external conical sleeve, the 3-floor clip, the 4-round nut, the 5-screw thread, 6-cooperates the conical surface, 7-wheel hub, 8-transmission shaft, 9-swelling seam A, 10-swelling seam B.
Embodiment
Below in conjunction with accompanying drawing the utility model is done further description:
As shown in the figure, a kind of expansion set by nut and taper fit locking, it comprises inner conical drogue 1, external conical sleeve 2 and round nut 4; Inner conical drogue 1 is enclosed within on the transmission shaft 8, and external conical sleeve 2 is enclosed within on the inner conical drogue 1, and cooperates the conical surface 6 with inner conical drogue 1 formation; Wheel hub 7 is enclosed within on the external conical sleeve 2, is respectively equipped with swelling seam A9 and swelling seam B10 on inner conical drogue 1 and the external conical sleeve 2, and inner conical drogue 1 outside one end is provided with screw thread 5; Round nut 4 is connected through screw thread 5 and inner conical drogue 1, accompanies floor clip 3 between round nut 4 and the wheel hub 7.
The working procedure of the utility model is following: when wheel is installed, inner conical drogue 1 is enclosed within on the transmission shaft 8, external conical sleeve 2 is enclosed within on the inner conical drogue 1, wheel hub 7 is enclosed within on the external conical sleeve 2; Install floor clip 3, tighten round nut 4, external conical sleeve 2 advances in the wheel hub 7 along the cooperation conical surface 6 wedges under the effect of round nut 4; Swelling seam A9 shrinks, inner conical drogue 1 banding transmission shaft 8, and swelling seam B10 shrinks; External conical sleeve 2 swelling wheel hubs 7, like this, wheel hub 7 is just on fastening connection firmly and the transmission shaft 8; Dismounting is during wheel, unscrews and withdraws from round nut 4, and at this moment, external conical sleeve 2 is along cooperating the conical surface 6 to withdraw from wheel hub 7 gradually, and swelling seam A9 stitches B10 with swelling and expands gradually, and inner conical drogue 1 unclamps transmission shaft 8, just detachably descends wheel.The utility model is specially adapted to the less mechanical transmission occasion of structure, can guarantee the installation precision of mechanical parts, improves mechanical transmission performance.
