Abstract
The utility model discloses a kind of key and connect wheel hub, wheel hub has center hole through vertically, the hole wall of center hole is provided with the through logical keyway extended vertically, the hole wall of described center hole is provided with the blind keyway of non-penetrating length and the key adaptation extended vertically at least side of logical keyway, be provided with the opening that donating bond passes when centrally hole rotates in a circumferential direction between described logical keyway and blind keyway, described blind keyway is between the both ends of the surface of wheel hub.In use, the axle being provided with key is penetrated in wheel hub, key enters wheel hub inside along logical keyway, rotatingshaft makes key follow rotation, key turns in blind keyway along the opening between logical keyway and blind keyway, and key can play the effect to wheel hub axial limiting on axle, no longer needs to carry out axial limiting by the shaft shoulder, axle head gland or axle sleeve to wheel hub, decrease the usage quantity of part, take up room little.
Description
Technical field
The utility model relates to a kind of key and connects wheel hub.
Background technique
The radial means of fixation of the wheel hub that conventional keys connects adopts the mode of key connection, wheel hub and axle carry out power transmission by key, the center hole hole wall of wheel hub is provided with the through logical keyway of centrally centerline hole direction extension, the axial restraint mode of wheel hub adopts jackscrew, the shaft shoulder, axle head gland, or add axle sleeve in wheel hub both sides, but find in actual design with in using, adopt jackscrew fixing firm not, adopt the shaft shoulder and axle head gland and axle sleeve all can be subject to the restriction of space and certain condition and be inconvenient to use, and add the quantity and weight of part, processing cost also can increase.
Summary of the invention
The purpose of this utility model is to provide a kind of key to connect wheel hub, to solve the problem that existing hub spindle takes up room greatly to means of fixation, amount of parts is many.
To achieve these goals, the utility model adopts following technological scheme: a kind of key connects wheel hub, there is center hole through vertically, the hole wall of center hole is provided with the through logical keyway extended vertically, the hole wall of described center hole is provided with the blind keyway of non-penetrating length and the key adaptation extended vertically at least side of logical keyway, be provided with the opening that donating bond passes when centrally hole rotates in a circumferential direction between described logical keyway and blind keyway, described blind keyway is between the both ends of the surface of wheel hub.
The hole wall of described center hole is equipped with blind keyway in the both sides of logical keyway.
The blind keyway of described logical keyway both sides is symmetrical arranged about logical keyway.
The beneficial effects of the utility model are: the utility model key connects wheel hub, the hole wall in hub centre hole is provided with at least side of logical keyway the non-penetrating blind keyway extended vertically, the logical opening being provided with donating bond between keyway and blind keyway and passing when centrally hole rotates in a circumferential direction, in use, the axle being provided with key is penetrated in wheel hub, key enters wheel hub inside along logical keyway, after entering into desired location, rotatingshaft makes key follow rotation, key turns in blind keyway along the opening between logical keyway and blind keyway, due to the length of blind keyway and key is adaptive and blind keyway is between the both ends of the surface of wheel hub, therefore key can play the effect to wheel hub axial limiting on axle, no longer need to pass through the shaft shoulder, axle head gland or axle sleeve carry out axial limiting to wheel hub, decrease the usage quantity of part, take up room little, also can reduce costs.
Accompanying drawing explanation
Fig. 1 is the plan view of embodiment of the present utility model;
Fig. 2 is the A-A sectional view of Fig. 1.
Embodiment
A kind of key of the utility model connects the embodiment of wheel hub, as shown in Figure 1-2: wheel hub 1 has center hole through vertically, the hole wall of center hole is provided with the through logical keyway 4 extended vertically, the hole wall of center hole is provided with the non-penetrating blind keyway 2 extended vertically in the bilateral symmetry of logical keyway 4, the logical opening being provided with donating bond 3 between keyway 4 and blind keyway 2 and passing when centrally hole rotates in a circumferential direction, blind keyway 2 is between the both ends of the surface of wheel hub 1, the length of blind keyway 2 and key 3 adaptation.
In use, first be arranged on axle 5 by connecting the key 3 of wheel hub 1 with axle 5, the axle 5 being provided with key 3 is penetrated in wheel hub 1, it is inner that key 3 enters wheel hub 1 along logical keyway 4, after entering into desired location, rotatingshaft 5 makes key 3 follow rotation, key 3 turns in blind keyway 2 along the opening between logical keyway 4 and blind keyway 2, due to length and key 3 adaptation of blind keyway 2, key 3 can play the effect to wheel hub 1 axial limiting on axle 5, for the wheel hub of Double-directional rotary, also need to load wedge key in logical keyway, with spacing to wheel hub radial direction.For the wheel hub of one-way rotation, can select key to be arranged in the blind keyway of the side contrary with hub rotation direction, can not wedge key be re-used.
In other embodiments, only non-penetrating blind keyway can be set in the side of logical keyway.
In the present embodiment, two blind keyways are arranged in the bilateral symmetry of logical keyway, are conveniently to process the through slot that donating bond is rotated through, and in other embodiments, also can asymmetricly arrange.
The structure that key of the present utility model connects the keyway of wheel hub can be applied to gear, in the design that sprocket wheel, belt wheel etc. connect with the use key of wheel hub.
