Poor in order to overcome axle sleeve connection reliability between existing large-scale ceiling fan wheel hub and motor shaft, the generation of wheel hub slippage and the manufacture of axle sleeve can not be stopped completely and complicated technical problem is installed, the purpose of this utility model is to provide a kind of taper self-locking device connecting wheel hub and axle, it can not only stop the slippage in operation process of industrial ventilation huge ceiling fan wheel hub, can also solve the manufacture of axle sleeve and install complicated technical problem.
For solving the problems of the technologies described above, the utility model provides a kind of taper self-locking device connecting wheel hub and axle, is arranged on the wheel hub of ceiling fan and the joint of motor shaft, comprises:
Hub base, is provided with conical through-hole, offers driver slot at the sidewall of this conical through-hole;
Axle sleeve, similar to the conical through-hole shape in hub base, this axle sleeve be axially arranged with the cylindrical hole that can wear motor shaft, its arranged outside has outside thread, and bottom is provided with U-type groove, and side is provided with flat key groove, and locking slot;
Sleeve nut, locks with the external thread rotary on axle sleeve and coordinates;
Flat key, is arranged on motor shaft, is provided with empty avoiding step;
Disk cover, is provided with bolt hole, and top is provided with an annular groove;
Described axle sleeve is placed in the conical through-hole of described hub base matchingly, U-type groove bottom axle sleeve is in order to the place tool when locking, flat key side is arranged on the flat key screens of motor shaft, side contacts with the driver slot in hub base through the flat key groove on axle sleeve, when electric machine rotation, flat key drive hub base rotates, tapped hole is provided with bottom motor shaft, disk cover is bolted the tapped hole bottom motor shaft and is arranged on motor shaft ends, annular groove inside is extend into bottom sleeve nut when the external thread rotary of sleeve nut and axle sleeve is locked, U-type groove is in order to the place tool when locking, the flat key be arranged on motor shaft passes flat key groove, when outside thread and sleeve nut are locked, locking slot diminishes by stress, thus allow axle sleeve and motor shaft lock tighter.
In order to reach better goal of the invention, the utility model also has following technological scheme:
Described flat key groove and locking slot corresponding be opened in axle sleeve both sides.
Described sleeve nut is Upper shaft sleeve nut and Lower shaft sleeve nut composition.
Employing technique scheme and existing fan electromotor wheel hub have compared with being connected and fixed with the axle sleeve of motor:
Coordinate when hub base and axle sleeve are tapered, greater weight hub base presses down by gravity, because the up-small and down-big cone shape hole of wheel hub and the axle sleeve of same profile coordinate, the wheel hub dropped is made closely to be enclosed within the mutual self-locking of sleeve outer circle cone Surface forming, and wherein a part of downforce is converted into the enclasping force to sleeve member, due to axle sleeve axially have allow motor to put down to build through groove, and this groove reserved axle sleeve compacted after deformation space, when wheel hub presses down axle sleeve, axle sleeve radial direction diminish thus make inner cone part and motor shaft enclasping force larger, when axle sleeve outside thread and sleeve nut are locked, axle sleeve radial direction diminish thus make the inner cone part of axle sleeve and motor shaft enclasping force larger, axle sleeve is connected more firm with motor shaft.
