Description
Technical field
The utility model relates to forging process for fuel manufacturing fields, and in particular to a kind of directive wheel wheel hub convenient for fixed installation.
Background technique
Directive wheel, directive wheel is used for soft pipeline or steel wire, in the softwares linear object moving process such as nylon rope
Direction guidance, directive wheel have pulley structure, and directive wheel can play the role of labour-saving in certain projects or product, and directive wheel removes
The skin materials of its wheel body need special emphasis, guarantee to roll smooth, and the core component that directive wheel is mostly important, as
It is connected to the wheel hub of driving mechanism, quality superiority and the accuracy to connect with driving part, is to guarantee the practical work of directive wheel
Basic whether making smooth, traditional directive wheel wheel hub is all directly to realize reality clamping by bolt, and this mode is being taken turns
When hub rotates, hub forgeable piece and axis are easy to produce relative rotation, easily snap off bolt, and be not easy to tie up after hub forgeable piece abrasion
It repairs, needs to change entire wheel hub, waste time, increase cost.
Utility model content
What the utility model to be overcome is that hub forgeable piece and axis are connected by screw bolts and are easy to lose bolt, and grind in wheel hub
The problem of being not easy to detachable maintaining when damage, increasing cost, it is therefore an objective to which a kind of directive wheel wheel hub convenient for fixed installation is provided.
A kind of directive wheel wheel hub convenient for fixed installation, including hub forgeable piece, the hub forgeable piece middle part are equipped with axis hole, institute
It states and internal axle sleeve is installed inside axis hole, four groups of location holes, installation inside the location hole are angularly equipped in the middle part of the internal axle sleeve
There is positioning pin, the positioning pin tail end is equipped with limited block, and positioning pin side ring set has extruding spring, the extruding bullet
Spring one end connection limited block other end is located at internal axle sleeve lateral surface, corresponds to position of positioning hole between the axis hole and internal axle sleeve contact surface
Equipped with slot, mandril is installed inside the slot, described mandril one end is located at location hole, and the other end is fixedly connected on fixation
On circle, the retainer plate is mounted on the axis hole end side of hub forgeable piece by stop screw invaginating.
Further, inside the slot equalization invagination to hub forgeable piece and internal axle sleeve, the slot section and mandril are cut
Face is identical.
Further, the retainer plate internal diameter is greater than internal axle sleeve internal diameter and is less than shaft hole diameter.
Further, the limited block lateral surface and mandril end are arc surface.
Further, the axis hole end side of the hub forgeable piece is equipped with convex stop collar, institute without installation retainer plate one end inside
It states convex stop collar minimum diameter and cushion is installed greater than internal axle sleeve interior diameter, the convex stop collar and inner shaft inner room.
The beneficial effects of the utility model are:
The utility model structure is simple, by installing internal axle sleeve inside the axis hole of hub forgeable piece, using in the middle part of internal axle sleeve
Positioning pin inside location hole is clamped axis, and when needing for axis and hub forgeable piece to be attached, retainer plate is passed through stop screw
It is fixedly mounted on axis hole one end, the mandril on retainer plate is inserted into inside slot, and thimble rod end jacks up limited block, and limited block pushes
Positioning pin is clamped axis to stretching on the inside of axis, in entire connection procedure, without using being bolted wheel hub and axis, but it is logical
Cross bolt by retainer plate be fixed on wheel shaft axis hole one end, wheel hub and retainer plate rotation when generate resistance it is small, bolt not easy to wear,
And internal axle sleeve is only needed to change when wheel hub is worn, it is not necessarily to wheel hub integral replacing, save the cost and time.
It is invaginated by setting slot equalization to inside hub forgeable piece and internal axle sleeve, the slot section and mandril section phase
Together, wheel hub internal axle sleeve and hub contacts face discontinuity in rotation are avoided, avoids hub forgeable piece and internal axle sleeve from occurring opposite
Rotation.
It is greater than internal axle sleeve internal diameter by setting retainer plate internal diameter and is less than shaft hole diameter, avoids retainer plate friction shaft, influence
The fixed effect of retainer plate.
It is arc surface by setting limited block lateral surface and mandril end, ejects limited block convenient for mandril.
By the axis hole end side of hub forgeable piece without installation retainer plate one end on the inside of be equipped with convex stop collar, fixed axostyle,
Prevent axis hole at internal axle sleeve offset.
