Description
Technical field
The utility model relates to mechanical transmission, and it is a kind of belt pulley clutch that the inside and outside suit pressure spring of six groups of diameter overstrikings is arranged.
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, its power input shaft is passed to belt pulley or opposite through the synergy of driving disc, driven disc, pressure disk with power, and the thrust that many group springs produce the compaction pressure dish is housed 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, its three groups of branch spaces such as press spring base, but the space distribution of 9 pressure spring slots of sum is circumference in equal parts not, because of the diameter of each spring thin (maximum spring diameter is 30mm), need a plurality of 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.
Summary of the invention
The purpose of this utility model is that prior art is improved, and a kind of overstriking six group of spring oil seal type belt pulley clutch is provided, and it uses six groups of interior overcoat springs of overstriking, simplified structure reduces pressure spring quantity, makes the stressed even of each pressure spot, increase the service life, reduce cost.Improve sealing configuration simultaneously, prevent leakage of oil.
The purpose of this utility model is achieved in that
A kind of overstriking six group of spring oil seal type belt pulley clutch, between its belt pulley housing and power input shaft, the friction lamella clutch is housed, this clutch has driving disc, be fixed in the gland of housing, be connected in the pressure disk of housing and the wearing piece between gland, driving disc, pressure disk with adjusting screw; Between platen and housing, be provided with pressure spring, on housing, respectively be connected with separator levers in three of the circumference in equal parts setting lever seats, described power input shaft by be contained in the housing and gland in the bearing supporting, between power input shaft and housing, be provided with Sealing, described pressure spring is divided in the corresponding stage clip support slot in six positions on pressure disk and the belt pulley housing, be set with two little pressure springs of outer imperial palace in every group of stage clip support slot, these six groups of stage clip support slot circumference in equal parts are provided with.
The pressure spring of described inside and outside suit, the diameter of its outer ring pressure spring is between 35～40mm.
There is thickened portion at the corresponding stage clip support slot of the outer wall of described belt pulley housing place.
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 the side of the bearing of supporting power input shaft.
Described oil seal type seal ring is the oil resistant rubber seal ring that spring and skeleton are arranged.
The utility model has following actively useful effect:
This product is provided with six groups of stage clip support slots between pressure disk and belt band housing, six stage clip support slot circumference in equal parts, be provided with two pocketed springs of diameter overstriking in each groove, its maximum spring external diameter is to 40mm, because the quantity of pressure spring is few and be equally spaced, thereby the pressurized of each pressure spot is even.The quantity of stage clip support slot and pressure spring reduces makes designs simplification, and overcoat spring in overstriking of pressure spring diameter and the use increases transmitting torque, and each pressure spot is stressed evenly can to increase the service life favourable reducing cost.Owing to the sealing configuration that has improved between power input shaft and the belt pulley housing, stop leakage of oil in addition, also reduced user cost.
