Embodiment
Principle of the present utility model and feature are described below in conjunction with accompanying drawing, example is served only for explaining this practicality
It is new, it is not intended to limit the scope of the utility model.
Fig. 1 is the top view of the monomer moulding casting nylon wheel of the utility model embodiment.Referring to Fig. 1, the utility model is implemented
Example provides a kind of monomer moulding casting nylon wheel, including：Nylon wheel body 10, the nylon wheel body 10 include coupling from inside to outside
Integral wheel hub 11, wheel web 12 and wheel rim 13, in radial direction side of the wheel both sides of web 12 along the nylon wheel body 10
To equally distributed n bars reinforcement 20 is correspondingly provided with, the reinforcement 20 connects the wheel hub 11 and the wheel rim 13, wherein, n
For non-zero even number.
The design after the nylon wheel optimization of pitch diameter specification of the same race is set to reach same bearing capacity and suitable deformation
Displacement, ensure the security and comfortableness of elevator operation, can be according to the method for the quantity of even number reinforcement 20.This practicality
It is new by setting non-zero even number bar reinforcement 20 on nylon wheel body 10, to increase the fulcrum force of wheel rim 13, need simultaneously
Ensure the stress balance of nylon wheel, to ensure the overall stress intensity of nylon wheel and suitable deformation displacement amount, can so subtract
The thickness of small wheel rim 13 and wheel hub 11, to reach the purpose for reducing material.
At present in the design of traditional structure, the quantity of reinforcement 20 only has the design of 6 and 9, so for nylon wheel
Especially for the larger nylon wheel of pitch diameter, the discontinuity of nylon wheel body 10 between two neighboring reinforcement 20, easily
Deformation, reduce the service life of nylon wheel.Therefore, we are by increasing the quantity of reinforcement 20, so increase fulcrum force with
Meet the load-carrying ability of nylon wheel body 10, while reach the purpose for saving material.
According to the nylon wheel of specification of the same race, maximum weighted mode be steel wire rope in nylon wheel grooving 14 with nylon wheel
When cornerite is 180 degree, we are appreciated that it in the range of cornerite, and the distribution of force of nylon wheel is Sine distribution mode.When adding
It is equal around the quantity of reinforcement 20 at left and right sides of the steel wire rope of nylon wheel when the quantity of strengthening tendons 20 is even number, uniform force.Can be with
Improve the integrally-built stability of nylon wheel.
Wherein, the corresponding camber line length in the inner circle of wheel rim 13 of central angle that the center line of two neighboring reinforcement 20 is formed
Degree is no more than 320mm.
With effective pitch diameter of elevator nylon wheel point, regular size has ￠ 320, ￠ 350, ￠ 400, ￠ 440, ￠ 480, ￠
500th, ￠ 520, ￠ 540 and ￠ 640 etc..
In the utility model embodiment, the central angle that the center line of two neighboring reinforcement 20 is formed is corresponded to and taken turns
Camber line on edge 13 is defined as C, and camber line C is shorter, is more unlikely to deform during nylon wheel stress, and camber line is longer, gets over during nylon wheel stress
It is easily deformed.Displacement (the elasticity of the malformation amount and material of nylon wheel in itself when therefore, in order to reduce nylon wheel stress
The summation of variable), the utility model embodiment design limitation camber line C size, further, because reinforcement 20 is evenly distributed on
On nylon wheel body 10, camber line C size can be limited with this by increasing the quantity of reinforcement 20.
But the quantity of reinforcement is not The more the better yet, reinforcement quantity easily brings following drawback too much：
If reinforcement is excessive, mould opens up also can be more complicated；In casting link, mobility of the material in mold cavity is poor, leads
Cause difficult forming, and demoulding difficulty；It is not high using clamping with three-jaw chuck, clamping precision in clamping link.Therefore, reinforcement
Quantity to be advisable no more than 42.
Referring to Fig. 2, for nylon wheel body 10, the thickness of the radial direction of nylon wheel as nylon wheel body 10
Direction is spent, the axial direction of nylon wheel body 10 is as width.
Wherein, the thickness c of the wheel rim 13 is 10mm-20mm.
When nylon wheel stress, the wheel rim 13 of the maximum displacement position of nylon wheel between two adjacent reinforcements 20,
The size of displacement (summation of the elastic module of the malformation amount and material of nylon wheel in itself) herein determines elevator operation
Comfort quality., can only be by increasing the quantity of reinforcement 20 and thickening the thickness of wheel rim 13 in order to reduce its force displacement
To improve the comfortableness of elevator operation, but the quantity of reinforcement 20 can influence the production efficiency of nylon wheel too much.The thickness of wheel rim 13
If too small, it is impossible to ensure its stress intensity, if the thickness of wheel rim 13 is too big, material cost can be influenceed again, so in design,
Need to consider, finally, the minimum thickness using 10mm-20mm as wheel rim 13.
Wherein, the thickness d of the wheel hub 11 is at least 10mm.
It is necessary when we design because the thickness of wheel hub 11 influences whether nylon wheel and bearing or the coordinate force of metal lining
To consider to ensure that it is cased with bearing or metal liner certain coordinate force when temperature raises, be unlikely to allow bearing or metal liner
Being enclosed on has the risk of loosening in nylon wheel endoporus.Finally, the minimum thickness using 10mm as wheel hub 11.
Wherein, the width a of the wheel web 12 is at least 4mm.
The effect for taking turns web 12 is fixed reinforcement 20 and the support to wheel rim 13, in nylon wheel stress, reinforcement 20
Stability ensure outer except the thickness and length dimension of itself, also want the guarantee of roller web 12；Secondly, the displacement of wheel rim 13
Amount number also with wheel web 12 width it is relevant.Finally, the minimum widith using 4mm as wheel web 12.
For using reinforcement 20 as main body, the length direction of the radial direction of nylon wheel as reinforcement 20, nylon wheel
Thickness direction of the circumferential direction as reinforcement 20, the width of the axial direction of nylon wheel as reinforcement 20.
Wherein, the thickness b of the reinforcement 20 is at least 4mm.
The intensity of reinforcement 20 influences whether the integrally-built stability of nylon wheel.In the certain feelings of the thickness of reinforcement 20
Under condition, its stress intensity can weaken with its extended length.
Referring to Fig. 2, the outside of wheel rim 13 is provided with several groovings 14, the width H of the reinforcement 201Meet formula
And formula (2) (1)：
L≤H1≤H (1)
L=(N-1) × M (2)
In formula (1) and formula (2), H1For the width of reinforcement 20,
H is the width of nylon wheel body 10,
N is the quantity of grooving 14,
M is pitch, i.e., the centre distance of two neighboring grooving 14,
L is resultant pitch, i.e. the centre distance of two groovings 14 of outermost.
When nylon wheel stress operates, reinforcement 20 plays a part of supporting wheel rim 13, allows wheel rim 13 not have excessive
Displacement, so as to ensure the comfortableness of elevator.Its size must is fulfilled for L≤H1≤H.Work as H1During less than L, to the outermost of nylon wheel
The force part of grooving 14 of side does not just have supporting role, and nylon wheel maximum displacement at this moment can be excessive, and elevator can be run
Safety belt carrys out hidden danger；Work as H1During more than H, consider that unnecessary waste can be produced from design angle, then have and can exactly influence nylon
Take turns the installation dimension between miscellaneous part, have interference during operating, there is hidden danger.Therefore, the width of reinforcement 20 should meet：L
≤H1≤H。
So that the thickness of wheel rim 13 is 10mm and 20mm as an example, the elevator nylon wheel progress reinforcement 20 of regular size is designed.
Thus, it is 10mm and 20mm that the camber line C corresponding to any flange thickness between 10mm-20mm, which should also be as in flange thickness,
Within the scope of each self-corresponding camber line C is formed.Table 1- tables 9 are the parameters of the reinforcement 20 of the elevator nylon wheel of regular size
Scheme.
In table 1- tables 9, D is effective pitch diameter of elevator nylon wheel；C is flange thickness；E is the minimum diameter of wheel rim 13；N is to add
