Abstract
The utility model discloses a kind of drum structure preventing treadmill belt sideslip, comprise treadmill, the bearing of treadmill both sides is provided with one group of roller, roller is provided with belt, rotating shaft and the bearing interference fit be arranged on bearing at described roller two ends, two end faces of roller are provided with cone boss symmetrically, and belt slides between cone boss.The utility model arranges one group of cone boss symmetrically on two end faces of roller, and therefore belt can only remain between cone boss and slide, thus avoids treadmill belt sideslip and cause belt Fast Wearing.
Description
Technical field
The utility model relates to a kind of drum structure, particularly relates to a kind of drum structure preventing treadmill belt sideslip.
Background technology
Along with the continuous quickening of rhythm of life, modern because of work busy, daily life system is abnormal, long-term lacking modest movement, causing neck to take on back aches thereupon, add the eating habit not having reasonably healthy, before lower body of accumulating over a long period is much worse than, therefore most people is in sub-health state.Popularizing in recent years based on health idea, the motion that people realize gradually is to healthy importance, particularly whole body aerobic exercise can effective human activin function, and treadmill can be good at the body-building demand meeting modern, being the simplest a kind of in current family fitness equipment, is the optimal selection of Domestic health care exercising apparatus.But the fault that existing treadmill the most easily occurs is belt deviation, belt deviation brings huge wearing and tearing to belt, causes treadmill to be shaken, and cannot run, even damage.
Utility model content
The purpose of this utility model is, provides a kind of structure simple, easy for installation, effectively can prevent the drum structure of treadmill belt sideslip, to overcome prior art deficiency.
The technical solution of the utility model: a kind of drum structure preventing treadmill belt sideslip, comprise treadmill, the bearing of treadmill both sides is provided with one group of roller, roller is provided with belt, rotating shaft and the bearing interference fit be arranged on bearing at described roller two ends, two end faces of roller are provided with cone boss symmetrically, and belt slides between cone boss.
Described belt two ends are provided with taper groove, and its tapering is consistent with the tapering of cone boss.
The tapering of described cone boss is 30 ° ~ 60 °.
Described bearing is deep groove ball bearing, the vibrations produced when this class bearing can bear running, but also has certain aligning ability, can eliminate treadmill and use the axial error produced on roller long afterwards, ensure that treadmill operates steadily.
Compared with prior art, the utility model has the advantage of: the utility model arranges one group of cone boss symmetrically on two end faces of treadmill roller, therefore belt can only remain between cone boss and slide, thus avoids treadmill belt sideslip and cause belt Fast Wearing.Therefore, it is simple, easy for installation that the utility model has structure, can improve the advantage in treadmill service life.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 1 is the A-A sectional view of Fig. 2.
Description of reference numerals: 1-treadmill, 2-bearing, 3-cone boss, 4-belt, 5-roller, 6-bearing, 7-rotating shaft, 8-taper groove.
Detailed description of the invention
In order to make the utility model object, technical scheme and advantage clearly, below in conjunction with drawings and Examples, the utility model is described in further detail.
Embodiment
Prevent the structural representation of the drum structure of treadmill belt sideslip as shown in Figures 1 and 2, comprise treadmill 1, the bearing 6 of treadmill 1 both sides is provided with one group of roller 5, roller 5 is provided with belt 4, rotating shaft 7 and bearing 2 interference fit be arranged on bearing 6 at described roller 5 two ends, two end faces of roller 5 are provided with cone boss 3 symmetrically, and the tapering of described cone boss 3 is 30, and belt 4 slides between cone boss 3.
Further preferably, taper groove 8 is arranged at belt 4 two ends, and its tapering is consistent with the tapering of cone boss 3.
Further preferably, bearing 2 is deep groove ball bearing, the vibrations produced when this class bearing can bear running, but also has certain aligning ability, can eliminate treadmill and use the axial error produced on roller 5 long afterwards, ensure that treadmill operates steadily.
