Abstract
The utility model discloses a kind of driving-wheel device, including drive and power transmission shaft, the drive and power transmission shaft are equipped with axial keyway in the relevant position of junction, drive and power transmission shaft are driven together by being embedded axial flat key in the axial keyway, the end of the drive and power transmission shaft is equipped with radial direction keyway in line in diametric(al), it is equiped with radial direction flat key in the radial direction keyway, the end of drive and power transmission shaft is linked into an integrated entity by the radial direction flat key.Driving-wheel device of the present utility model makes the impact extruded power born originally by single axial flat key, is undertaken now by double bond, reduces the impact to axial bond and axial keyway, it is possible to resolve problems of the prior art, greatly prolong the service life of equipment.Have the advantages that simple in construction, transmission effect it is good, can the service life of extending shaft wheel and applied widely.
Description
Technical field
The utility model is related to mechanical transmission fields, more particularly to a kind of driving-wheel device.
Background technology
In the prior art, in the drive equipment such as general V-belt wheel, gear, sprocket wheel, drive and power transmission shaft it
Between connection transmission be use standard flat key.There are many defects in the structure：When standard flat key and its keyway pass through one section
Between repeated stock extrusion after, easily make flat key become diamondwise, make keyway become flue, more seriously keyway stress
It can also be broken over there, cause it not repair, greatly shorten the service life of drive equipment.
Utility model content
The technical problems to be solved in the utility model be overcome the deficiencies in the prior art there is provided one kind it is simple in construction, transmission
The driving-wheel device that effect is good, can increase the service life.
In order to solve the above technical problems, the utility model proposes technical scheme be：
A kind of driving-wheel device, including drive and power transmission shaft, the drive and power transmission shaft are in the corresponding positions of junction
Put and be equipped with axial keyway, drive and power transmission shaft are driven together by being embedded axial flat key in the axial keyway, described
The end of drive and power transmission shaft is equipped with radial direction keyway in line, the radial direction keyway in diametric(al) and is equiped with footpath
To flat key, the end of drive and power transmission shaft is linked into an integrated entity by the radial direction flat key.
It is used as the further improvement to above-mentioned technical proposal：
It is preferred that, the radial direction flat key is fixedly connected on the end of the power transmission shaft by a sunk screw.
It is preferred that, the outer surface of the radial direction flat key is concordant with the end face of the power transmission shaft and drive.
It is preferred that, the radial direction keyway is through the power transmission shaft and the end face of drive.
It is preferred that, the sunk screw is cross recessed countersunk head sscrew.
It is preferred that, the drive is V-belt wheel, gear or sprocket wheel.
It is preferred that, the radial direction flat key and axial flat key are standard component.
Compared with prior art, the utility model has the advantage of：
Transmission device of the present utility model, increases by a radial direction flat key in the end of power transmission shaft and drive, and it is designed, system
Make, installation, maintenance it is all very simple, and there is no any influence to other intensity of axle wheel, may be used also whereas for most weak place
Its intensity is greatly increased, makes the impact extruded power born by single axial flat key originally, is undertaken now by double bond, is reduced pair
The impact of axial bond and axial keyway, it is possible to resolve problems of the prior art, greatly prolongs the service life of equipment.Through examination
Test, used in many equipment especially ammonium nitrate disintegrating machine after device of the present utility model, the service life of its axle wheel can extend
More than one times.Have the advantages that simple in construction, effect is good, applied widely for transmission, energy-conserving and environment-protective.

Embodiment
For the ease of understanding the utility model, below in conjunction with Figure of description and preferred embodiment to the utility model
Work more comprehensively, is meticulously described, but protection domain of the present utility model is not limited to embodiment in detail below.
As shown in Figure 1-Figure 3, a kind of driving-wheel device embodiment of the present utility model, including drive 1 and power transmission shaft 2,
Drive 1 and power transmission shaft 2 are equipped with axial keyway in the relevant position of junction, and drive 1 and power transmission shaft 1 are by axial bond
It is embedded axial flat key 5 in groove to be driven together, the end of drive 1 and power transmission shaft 2 is equipped with footpath in line in diametric(al)
To keyway, radial direction flat key 3 is equiped with the radial direction keyway, the end of drive 1 and power transmission shaft 2 is connected by the radial direction flat key 3
Integrally.The utility model increases by a radial direction flat key in the end of power transmission shaft and drive, and its design, manufacture, installation, maintenance are all
It is very simple, and there is no any influence to other intensity of axle wheel, its intensity can be also greatly increased whereas for most weak place,
Make the impact extruded power born originally by single axial flat key, undertaken, reduced to axial bond and axial bond by double bond now
The impact of groove, it is possible to resolve problems of the prior art, greatly prolongs the service life of equipment.
In the present embodiment, radial direction keyway is through power transmission shaft 2 and the end face of drive 1.Radial direction flat key 3 passes through a sunk screw
4 are fixedly connected on the end of power transmission shaft 2, and the outer surface of radial direction flat key 3 is concordant with the end face of power transmission shaft 2 and drive 1.Make it
Appearance looks elegant, without interference with influence other equipment installation and use.
In the present embodiment, sunk screw 4 is cross recessed countersunk head sscrew.Drive 1 is V-belt wheel, gear or sprocket wheel.
In the present embodiment, radial direction flat key 3 and axial flat key 5 are standard component.
Lot of experiments through applicant, uses device of the present utility model in many equipment especially ammonium nitrate disintegrating machine
Afterwards, the service life of its axle wheel can extend more than one times.Therefore also demonstrating device of the present utility model has simple in construction, biography
Move the advantages of good, applied widely effect, energy-conserving and environment-protective.
