Abstract
The utility model discloses a separate automatic clutch which is chiefly composed of a driving shaft, a driving disc, a driven drum and a belt pulley. A brake shoe and an extension spring are arranged in the driving disc. The separate automatic clutch is characterized in that the driving shaft is separated from the driving disc and is an independent element. The belt pulley and the driven drum are connected in a dismountable way. The depth of the driven drum is not less than 40 millimeters. The thickness of the brake shoe is not less than 30 millimeters. The separate automatic clutch overcomes the defects that the driving shaft of the prior art product is easy to break, the brake shoe is easy to slip, the production cost is high and the speed can not be changed according to the rotary speed requirement of the equipment used by the user.
Description
The utility model belongs to a kind of clutch, relates in particular to a kind of the use and is being the clutch on the various machinery of power with diesel engine.
Before the utility model was made, the use of clutch was quite extensive.Wherein, centrifugal clutch widespread usage on the various machinery that with the diesel engine are power.Its structure mainly is made up of driving shaft, driving disc, passive drum and belt pulley, and brake shoe and extension spring are equipped with in driving disc inside.There is following shortcoming in the clutch of this structure in production practices:
(1) driving shaft and driving disc are designed to one, therefore, generally can only adopt the cast iron method during manufacturing, its material is generally magnesium iron, so, through regular meeting the driving shaft phenomenon of rupture takes place in use.So not only manufacture cost height, and driving shaft is fracture in a single day, and whole clutch will be scrapped immediately.
(2) because when manufacturing and designing, belt pulley and passive drum are single piece, and belt pulley can not separate with passive drum, therefore, it can not be according to the needs of customer equipment rotating speed and conversion rate.
(3) be subjected to existing passive bulging effect of depth, the width of brake shoe also is restricted, and therefore, because the brake area of brake shoe is narrow and small, the brake shoe skidding can usually occur in the use.
The purpose of this utility model provides a kind of split type automatic clutch.This product not only can be according to the needs of customer equipment rotating speed and conversion rate also has long service life, low cost of manufacture, overhaul conveniently, and promptly be that driving shaft damages the characteristics that also can not cause whole clutch to be scrapped.
The purpose of this utility model reaches by following technical proposals:
The utility model is a kind of split type automatic clutch, it is made up of driving shaft, driving disc, passive drum and belt pulley, and brake shoe and extension spring are equipped with in driving disc inside, and its structure outline is: driving shaft and driving disc split, be a monolithic piece, driving shaft links to each other with driving disc through bearing.
The utility model is preferably disassembly-type between belt pulley and the passive drum and is connected in the specific implementation.
The utility model in the specific implementation, the degree of depth of passive drum more preferably greater than or equal 40 millimeters.
The utility model in the specific implementation, the thickness of brake shoe more preferably greater than or equal 30 millimeters.
The utility model compared with prior art owing to driving shaft and driving disc split design, make driving shaft become a monolithic piece, makes driving shaft link to each other with driving disc through bearing; And be connected being designed to disassembly-type between belt pulley and the passive drum; Moreover the degree of depth of passive drum is more than or equal to 40 millimeters, and the thickness of brake shoe has increased by 20% brake area than 25 millimeters of original brake shoe thickness like this more than or equal to 30 millimeters.Prior art products driving shaft easy-rupturing, brake shoe easily skid, the cost of production height thereby overcome, and the equipment rotating speed needs that can not use according to the user and the shortcoming of conversion rate.Originally the reason that cost of production is high is, in order to consider the fastness of driving shaft, this single piece of driving disc and driving shaft needs to cast with magnesium iron, then can cast driving disc with general cast iron after the split now, and driving shaft can have been made with other material.
The utility model is described in further detail by embodiment below in conjunction with accompanying drawing.
Fig. 1 is the utility model embodiment sectional structure schematic representation.
Fig. 2 is the schematic representation of Figure 1A-A to sectional structure;
Fig. 3 is the utility model embodiment driving disc perspective view;
Fig. 4 is the passive bulging perspective view of the utility model embodiment;
Referring to accompanying drawing.The utility model is a kind of split type automatic clutch.Main parts size has bearing 1, bearing 2, plain washer 3, packing ring 4, round nut 5, shaft block ring 6, hole back-up ring 7, bolt 8, packing ring 9, belt pulley 10, passive drum 11, bearing pin 12, nut 13, packing ring 14, driving disc 15, friction is with 16, screw 17, brake shoe 18, extension spring 19, screw 20, packing ring 21, driving shaft 22, bearing support 23 has auxiliary hole 24 on the passive drum 11, positioning seat 25.
Driving shaft adopts 45
#Carbon constructional quality steel is a material, and through the intensity of Overheating Treatment (modified HRC28-32 degree) with the assurance driving shaft,
Present embodiment belt pulley 10 adopts disassembly-type to connect with being connected of passive drum 11, and promptly belt pulley 10 is located by connecting through bolt 8, packing ring 9 with passive drum 11.Like this, the requirement of the equipment rotating speed that uses according to the user can reach the purpose of replacing speed by the method for changing the belt pulley size.
Present embodiment is made 40 millimeters with the degree of depth of passive drum, like this, the thickness of brake shoe has also been done corresponding increase (seeing Fig. 1,2), present embodiment brake shoe thickness is 30 millimeters (brake shoe thickness originally is 25 millimeters), consequently: strengthened the brake area of brake shoe, with the appearance of skidding in preventing to use.
Driving disc, passive drum, belt pulley and brake shoe are HT200 cast iron, and all the other component are standard piece.
Below in conjunction with accompanying drawing narrate this clutch assembling and with the assembly process of diesel engine:
Referring to Fig. 1, Fig. 3.At first bearing 1, bearing 2 are installed in the bearing support 23 interior (bearing support 23 inside are a through hole, and two big or small platform levels are arranged on the hole wall, and on little bearing 1 built-in little the level, big bearing 2 is arranged on the big platform level of outside) of driving disc 15; Put into driving shaft 22, and, driving shaft 22 and driving disc 15 are tightened together with shaft block ring 6 location (axially locating); Again brake shoe 18 and extension spring 19 are installed on the driving disc 15; Then passive drum 11 is pressed into driving shaft 22, with plain washer 3, packing ring 4, round nut 5 location; Reinstall belt pulley 10, fastening with bolt 8.
This each structural member attachment bolt of split type automatic clutch must be seated on request, with the order of diesel engine assembling be: at first remove belt pulley 10, auxiliary hole 24 (referring to Fig. 4) on passive drum 11 again, with screw 20, packing ring 21, clutch component is loaded on the flywheel of diesel engine, tightens screw, then, transmission pulley is loaded on the positioning spigot of clutch part, and bolt is tightened.
