Abstract
The present invention relates to a kind of crawler belt treadmill roller, including roller wheel body made of hard plastic, it is wrapped in the flexible layer made of soft rubber outside roller wheel body.Will in the prior art the cylinder wheel made of metal or rigid plastics repack into it is internal formed by hard plastic injection molding, outside is wrapped to form two-layer cylinder wheel construction by soft PU；In contrast, this structure keeps overall mass, density smaller, simultaneously because internal be still made of rigid plastics, therefore integral hardness will not change, and outside is made of soft rubber, hardness is lower, thus during the work time, cylinder wheel with treadbelt when cooperating since resistance is smaller, crawler belt treadmill can be made more smooth during the motion, this structure more meets human engineering mechanics simultaneously, reduces damage during running, to knee.
Description
Technical field
The present invention relates to a kind of running machine part, in particular to a kind of crawler belt treadmill roller and crawler belt treadmill.
Background technique
Treadmill is the standing fitness equipment of family and gymnasium, and is simplest one in current family fitness equipment
Kind, it is the optimal selection of Domestic health care exercising apparatus；Nineteen sixty-five Northern Europe Finland Tang Teli has been born the treadmill of global First household, if
Meter teacher changes according to the principle for passing speed belt.
Existing crawler belt treadmill is mainly made of cylinder wheel and treadbelt, and treadbelt is by one layer of PVC rubber topmost, centre
One layer of polyester net, nethermost warp and weft composition.Cylinder wheel material is metal or duroplasts, and such cylinder wheel is whole
Hardness is larger, and not only overall weight is heavier, and influences the whole smoothness of treadmill.
Summary of the invention
The object of the present invention is to provide a kind of crawler belt treadmill roller and crawler belt treadmills.
Above-mentioned technical purpose of the invention has the technical scheme that
A kind of crawler belt treadmill roller, including roller wheel body made of hard plastic, be wrapped in outside roller wheel body
The flexible layer made of soft rubber.
It, will be in the cylinder wheel made of metal or rigid plastics repacks into the prior art by using above-mentioned technical proposal
Portion is formed by hard plastic injection molding, and outside is wrapped to form two-layer cylinder wheel construction by soft PU；In contrast, this structure makes whole
Machine quality, density are smaller, simultaneously because internal be still made of rigid plastics, therefore integral hardness will not change, and outer
Portion is made of soft rubber, and hardness is lower, thus during the work time, cylinder wheel when cooperating with treadbelt since resistance is smaller,
Crawler belt treadmill can be made more smooth during the motion, while this structure more meets human engineering mechanics, reduction is being run
Damage during step, to knee.
Preferably, the flexible layer uses soft polyurethane ester.
Preferably, the cylinder wheel ontology uses polypropylene.
Preferably, the preparation process of above-mentioned crawler belt treadmill roller mainly comprises the steps that
Step 1: polypropylene is injected into cylinder wheel mold, injection molding；
Step 2: soft polyurethane ester elastomer is wrapped in the roller wheel surface of injection molding in step 1.
Preferably, the step 2 is carried out using rubber coating machine.
Above-mentioned technical purpose of the invention has the technical scheme that
A kind of crawler belt treadmill roller, including treadbelt, the treadbelt are abutted with flexible layer.
Preferably, the treadbelt is set on flexible layer.
In conclusion the invention has the following advantages:
1, will in the prior art the cylinder wheel made of metal or rigid plastics repack into inside by hard plastic injection molding and
At outside is wrapped to form two-layer cylinder wheel construction by soft PU；In contrast, this structure keeps overall mass, density smaller, together
When be still made of rigid plastics due to inside, integral hardness will not change, and it is external be made of soft rubber, firmly
Spend lower, thus during the work time, cylinder wheel, since resistance is smaller, can be such that crawler belt treadmill is transporting when cooperating with treadbelt
It is more smooth during dynamic, while this structure more meets human engineering mechanics, reduces during running, to the damage of knee
Wound；
2, the cylinder wheel in this programme includes cylinder wheel ontology and flexible layer；Cylinder wheel ontology uses PP injection molding, soft
Property layer be that flexible PU is wrapped on cylinder wheel ontology using rubber coating machine, PP have good shock resistance, it is ensured that run
The steady running of step machine；Soft PU, also known as polyurethane elastomer are a kind of elastic materials between ordinary rubber and plastics
Material not only with the high resiliency of rubber, but also the high intensity with plastics, while having excellent oil resistant, impact resistance, low temperature resistant, resistance to
, there is good protective effect in the advantages that ozone, heat-insulated radiation hardness and weight bearing to internal cylinder wheel ontology.
Detailed description of the invention
Fig. 1 is overall structure of the explosion figure in embodiment 1；
Fig. 2 is structural schematic diagram in embodiment 2.
In figure, 1, cylinder wheel ontology；2, flexible layer；3, treadbelt.
Specific embodiment
Below in conjunction with attached drawing, invention is further described in detail.
This specific embodiment is only explanation of the invention, is not limitation of the present invention, those skilled in the art
Member can according to need the modification that not creative contribution is made to the present embodiment after reading this specification, but as long as at this
All by the protection of Patent Law in the scope of the claims of invention.
Embodiment 1:
A kind of crawler belt treadmill roller, as shown in Figure 1, including roller wheel body 1 made of hard plastic, being wrapped in rolling
Outer flexible layer 2 made of soft rubber of cylinder wheel body 1.
As shown in Figure 1, flexible layer 2 uses soft rubber, preferably polyurethane, polyurethane elastomer both had in the present embodiment
There is a high resiliency of rubber, and the high intensity with plastics, while there is excellent oil resistant, impact resistance, low temperature resistant, resistance to ozone, resistance to
It radiates and bears a heavy burden the advantages that heat-insulated.
As shown in Figure 1, cylinder wheel ontology 1 uses rigid plastics, it is preferably polypropylene in the present embodiment；Polypropylene has good
Good shock resistance, it is ensured that the steady running of treadmill.
The preparation process of roller the following steps are included:
Step 1: polypropylene is injected into cylinder wheel mold, injection molding；
Step 2: soft polyurethane ester elastomer is wrapped in the roller wheel surface of injection molding in step 1.
Step 1 after polypropylene is heated to molten condition, is injected into cylinder wheel mold, is then cooled and shaped, is obtained
Soft polyurethane ester elastomer (soft PU) is uniformly packaged in 1 table of roller wheel body followed by rubber coating machine by roller wheel body 1
Face forms flexible layer 2, and the two collectively constitutes a complete cylinder wheel, and 2 section of flexible layer is formed as concentric circles.
Rubber coating machine is the prior art, and this will not be repeated here.
Working principle:
When processing, polypropylene is injected into injection molding in cylinder wheel mold in advance, then by the roller after cooling and shaping
Wheel body 1 is removed from the molds, and is recycled rubber coating machine that soft PU is packaged in 1 circumference side of roller wheel body and is formed flexible layer 2.
Cylinder wheel after completing is installed to crawler belt treadmill, with the operating of crawler belt treadmill, cylinder wheel rotation, thus band
Dynamic treadbelt movement.
