The utility model is set to further: described groove chamber comprises main chamber that corresponding tensioning frame arranges and the secondary cavity that corresponding outer casing frame is arranged, main chamber and the mutual UNICOM of secondary cavity, and wherein, the interior opening without leave of main chamber tapers off to secondary cavity direction shape.
By adopting technique scheme, the internal diameter of main chamber being arranged to inclined plane shape, namely the thickness of tensioning frame changes from small to big so that tensioning frame has possessed elasticity capacity, and then improves the resistance to compression ability of tensioning frame.
The utility model is set to further: the diameter of described spacing section and the diameter ratio of tension section are 1.15-1.35.
By adopting technique scheme, when the diameter ratio of the diameter of spacing section and tension section is 1.15-1.35, the arrangement stability of belt and tensioning frame and the optimal stability of tensioning frame.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
With reference to Fig. 1, embodiment of the present utility model is described further.
A kind of belt pulley, comprise body, groove chamber 30 has been offered in body, body comprises interconnective tensioning frame 1 and outer casing frame 2, the intensive aspect 22 that outer casing frame 2 comprises housing 21 and is placed on housing 21, housing 21 comprises the outer section 21a being connected with the tensioning frame 1 and straight wall section 21b for installing intensive aspect 22, the diameter of intensive aspect 22 outwards tapers off shape by straight wall section 21b, tensioning frame 1 comprises interconnective spacing section 11 and tension section 12, the diameter of spacing section 11 is greater than the diameter of tension section 12, it is configured with stress section 13 for spacing section 11 with the junction of tension section 12, the curved shape of the outer wall of stress section 13, the radian of this stress section 13 is 37 °-45 °, outer section 21a is connected with tension section 12, and the junction of outer section 21a and tension section 12 is configured with transition shoulder, the diameter of outer section 21a tapers off shape to straight wall section 21b by tension section 12, section 21a both sides, outer outer wall is 37 °-45 ° relative to the angle of inclination of tension section 12.
By adopting technique scheme, the setting in groove chamber 30 reduces the weight of pulley body, it is to increase the rotating speed of belt pulley and the interior of groove chamber 30 can be coated with the effect that sticky lubricating oil plays cooling.
Tensioning frame 1 settles belt to use for tensioning, the resistance to compression of tensioning frame 1 and antitorque ability is substantially increased by arranging housing 21, when tensioning frame 1 is subject to the tensioning pressure of belt, transition shoulder also serves the effect as point of suppon, outer section 21a can produce the external force that counteracting tensioning frame 1 is subject to, ensure that the Stability Analysis of Structures of tensioning frame 1, and the setting of transition shoulder, decrease the rigid contact surfaces between outer section 21a and tensioning frame 1 to amass, and then improve the strength of joint of outer section 21a and tensioner. Particularly when section 21a both sides, outer outer wall is 37 °-45 ° relative to the angle of inclination of tension section 12, when tensioning frame 1 is more big by power, the ability that outer section 21a produces is also more big, ensure that tensioning frame 1 is not out of shape by power, and then improves the work-ing life of pulley body.
Improve the structural strength of outer casing frame 2 self by arranging intensive aspect 22, and the setting of intensive aspect 22 increases the moment of torsion of housing 21, and then improve the stability of pulley body in operational process.
Belt can be limited on tension section 12, prevent slipping of belt, skid off tensioning frame 1 for spacing section 11.
The setting of stress section 13 improves spacing section 11 strength of joint with tension section 12, and owing to stress section 13 is arc shape, therefore belt is with the contact process of stress section 13, it is not easy to worn and torn.
