Description
Technical field
The utility model relates to a kind of mechanical clutch means, i.e. four separator levers, 16 spring formula belt pulley clutches.
Background technique
The belt pulley transmission is used in the transmission system of many machinery, and it can be used for speed change and transmission high pulling torque, clutch is housed in belt pulley can conveniently realizes the transmission clutch, and is of many uses, particularly uses more in farm machinery.Existing clutch pulley combination, the general friction lamella clutch that uses is equipped with the thrust that many group springs produce the compaction pressure dish between pressure disk and belt pulley housing.The belt pulley clutch of prior art, a kind of is that pressure disk is provided with and adorns six pressure springs in six stage clip support slots, each spring is single spring and its diameter is less, thereby the spring thrust that produces is also less.Other has a kind of belt pulley clutch, three groups of press spring bases are arranged between its pressure disk and the belt pulley housing, every group of press spring base has two little springs of the outer imperial palace of dress in three stage clip support slots, whole 18 pressure springs of totally 9 grooves, the shortcoming of the clutch of this structure is: the many springs of groove are many, structure is simplified inadequately, technology capability is relatively poor, diameter thin (maximum spring diameter is 30mm) because of each spring, need many outer springs to exert pressure simultaneously and could produce the pressure that needs, and how spring also brings because of the long difference of spring makes each shortcoming spring energized and inequality, causes the discontinuity of each pressure spot, influences working life.In addition, be sealed into the seal form that dovetail groove adds felt between the power input shaft of prior art and the belt pulley housing, sealing is relatively poor, has oil leakage phenomenon.Separate unclear wearing piece when also usually sending out simultaneously, and add sliding phenomenon.Use is received the order low.
Summary of the invention
The purpose of this utility model is to provide a kind of four separator levers, 16 spring formula belt pulley clutches, and its transmitted power is big, separates clearly, reduces: the wearing piece wearing and tearing.Simultaneously, make the stressed even of each pressure spot, prolong to use and receive the order.Simultaneously, improve sealing configuration, prevent leakage of oil.
The purpose of this utility model is achieved in that a kind of four separator levers, 16 spring formula belt pulley clutches, comprise the wearing piece clutch is set between belt pulley housing and the pto, this clutch comprises: driving disc, be bolted in the gland of housing, pressure disk, wearing piece is positioned at the gland driving disc, between the pressure disk, between pressure disk and housing, be provided with pressure spring, separator levers mechanism is set on housing, it is characterized in that: its pressure spring divides four groups of circumference in equal parts, and every group is provided with identical two cover outer imperial palaces little uniform pressure springs and is arranged at spring-loaded groove by housing and pressure disk respectively, in; Four components are set from lever at housing place circumference in equal parts.
Described pto by in the casing body and gland in state hold support, between pto and housing, be provided with Sealing.
The corresponding stage clip support slot of the outer wall of described belt pulley housing, locate to be provided with the thickening convex.
Two its Hand of spiral of pressure spring of described inside and outside suit are identical.
Two its Hand of spiral of pressure spring of described inside and outside suit are opposite.
Sealing between described power input shaft and the housing is the oil seal type seal ring that is contained in the housing respective grooves, and the end face of sealing circle is dehisced in the face of supporting the side that power input shaft holds.
Described oil seal type seal ring is the oil resistant rubber seal ring that the skeleton of spring and skeleton is arranged.
Described pressure disk connects with housing with adjusting screw.
The pressure spring of described inside and outside suit, the diameter of its outer ring pressure spring is between 25～35mm.
The utility model is provided with eight stage clip support slots between pressure disk and belt pulley housing, two is one group, divides four groups of circumference in equal parts, is provided with two pocketed springs of diameter overstriking in each groove, its maximum spring external diameter is to 35mm, because the pressurized of each pressure spot of pressure spring is even.Overcoat spring in overstriking of pressure spring diameter and the use increases transmitting torque, and simultaneously, separator levers increases to four groups and equal circumference distribution by three groups, and it is clear that power is separated, and receives the order favourable reducing cost thereby raising wearing and tearing sheet uses.Owing to the sealing configuration that has improved between power input shaft and the belt pulley housing, stop leakage of oil in addition.
