Background technique

Two-wheel flute milling machine is a kind of heavy mechanical equipment for being exclusively used in diaphram wall, high-efficient with trenching construction, Hole shape rule, safety and environmental protection adapt to the remarkable advantages such as geology range in stratum is wide, therefore are generallyd use in countries in the world；? In the equipment course of work, in order to reduce the harm of vibration, prevent the milling of damage equipment or transmission parts, existing mostly use from subtracting Ring structure is shaken, can be effectively used for transmitting torque and plays the role of damping, including the input circle being connect with transmission parts and milling The output circle of component connection is cut, output ring is set to the periphery of input circle, the gap then formed between input circle, output circle Middle vulcanization has rubber bodies, is integrated so that inputting circle, rubber bodies and output circle vulcanization, but pass through the composite structure and its technique, After rubber bodies are cooling, will cause the shrinkage stress after rubber bodies vulcanize can not discharge, i.e. the limit by input circle, output circle System, rubber bodies residual shrinkage stress shorten the working life so that the durability of shock ring can be reduced.

Summary of the invention

For the damping ring structure of existing use, rubber bodies remain shrinkage stress, so that the durability of shock ring can be reduced, The problem of shortening the working life, the utility model provide Double-wheel milling power head shock-damping structure, can effectively extend durability And service life.

Its technical solution is such comprising input circle, rubber bodies, output circle, the input enclose and are equipped with groove, It is characterized by: it further includes the stamping parts for being located on the output and enclosing inside and outside circle, the output is enclosed corresponding inside and outside It is pressed in the groove after being integrated respectively with rubber bodies vulcanization between the stamping parts of circle.

It is further characterized by:

The output circle upper annular offers card slot, is provided with phase on the stamping parts of the inside and outside circle of the corresponding card slot The bayonet answered, the input circle, the upper equal annular distribution of output circle have screw hole；The width of the bayonet is less than the width of the card slot Degree；

The stamping parts of inside and outside circle is annular plate；The punching press of the input circle, output circle and inside and outside circle Part is all made of iron material matter；

The groove inner wall offers limiting slot corresponding with the card slot, the output circle, rubber along its groove depth direction The vulcanization of the stamping parts of colloid and inside and outside circle, which is integrated and is pressed in the groove, is plugged in the limit by limit plate afterwards It is limited in the slot of position, and the limit plate matches with the bayonet；

At least provided with two, the width of the card slot is greater than the width of the limiting slot for the card slot, bayonet, limiting slot Degree；The limiting slot along it is described input circle groove circumferentially.

The manufacturing method of Double-wheel milling power head shock-damping structure, it is characterised in that: itself the following steps are included:

(1), the rubber bodies first carry out whole vulcanization, vulcanization with the stamping parts of the output circle and inside and outside circle After the completion in the groove of the whole indentation input circle；

(2), will after vulcanization is completed in the step (1) component is integrally pressed into the groove, with the card slot and Limit plate is inserted at bayonet in the corresponding limiting slot to be limited.

The utility model has the beneficial effects that first being carried out with the stamping parts of output circle and inside and outside circle by rubber bodies whole Body vulcanization after the completion of vulcanization in the groove of whole indentation input circle, can make rubber bodies and output circle free shrink after curing, Internal stress is eliminated, and in process of press in, there is certain decrement, so as to extend the endurance quality of shock-damping structure, and Service life.

Specific embodiment

As shown in Fig. 1 ~ Fig. 5, the utility model includes input circle 1, rubber bodies 2, output circle 3, is equipped on input circle 1 recessed Slot 4, further include be located on output circle 3 inside and outside circles stamping parts 5, output circle 3 corresponding inside and outside circles stamping parts 5 it Between respectively with rubber bodies 2 vulcanization be integrated after be pressed in groove 4.

Output 3 upper annulars of circle offer card slot 6, are provided with corresponding bayonet on the stamping parts 5 of the inside and outside circle of corresponding card slot 6 7, input circle 1, output, which enclose annular distribution on 3, screw hole 8；The width of bayonet 7 is less than the width of card slot 6；The punching press of inside and outside circle Part 5 is annular plate；The stamping parts 5 of input circle 1, output circle 3 and inside and outside circle is all made of iron material matter；At work, existing to subtract Shake ring structure is easy to the case where will appear torque overload in equipment start-stop due to not having position limitation protection function, and is easy to Causing the damage of rubber bodies, in the present invention, 4 inner wall of groove offers limiting slot 9 corresponding with card slot 6 along its groove depth direction, The vulcanization of stamping parts 5 of output circle 3, rubber bodies 2 and inside and outside circle is inserted after being integrated and being pressed in groove 4 by limit plate 10 It is limited in limiting slot 9, and limit plate 10 matches with bayonet 7, the limit of torque and axial direction can be provided simultaneously by limit plate 10 Bit function；Card slot 6, bayonet 7, limiting slot 9 are equipped with 6, and the width of card slot 6 is greater than the width of limiting slot 9；69 edges of limiting slot The groove 4 of input circle 1 is circumferentially.

The manufacturing method of Double-wheel milling power head shock-damping structure, that it changes existing vulcanizations, can make 2 He of rubber bodies The free shrink after curing of circle 3 is exported, internal stress is eliminated, extends the endurance quality of shock-damping structure, specifically include following step It is rapid:

(1), rubber bodies 2 first carry out whole vulcanization with the stamping parts 5 of output circle 3 and inside and outside circle, whole after the completion of vulcanization In the groove 4 of indentation input circle 1, and the global facility has certain decrement in process of press in, and such as pre-compression force can increase Strong endurance quality；

(2), will after vulcanization is completed in step (1) component is integrally pressed into groove 4, with corresponding limit at bayonet 7 Insertion limit plate 10 is limited in the slot 9 of position, the limit function of torque and axial direction can be provided simultaneously by limit plate 10, also into one Step improves the security performance of shock-damping structure, can greatly reduce the time of equipment downtime maintenance, and disassembly installation is also more convenient.
