The friction-type soft start energy-saving safety joint slack has small bulk, convenient installment, stable operation and convenient maintenance, simultaneously can adapt to requirements of frequent over-loading working conditions, and has high nominal torsion accuracy, which is a high-speed soft start driving device with high practical values, and is widely applied in industry mechanical transmission systems.
Description
Technical field
The utility model relates to a kind of coupling, specifically, relates to a kind of friction type soft start energy-saving safety coupling.
Background technique
In part transmission occasion, exist starting load big, impact phenomenon strong but that the balance movement back loading reduces again greatly, one of method that addresses this is that usually is exactly the power that increases prime mover, still, can increase the consumption and the equipment cost of the energy so again; Two of method is to adopt electric soft start, but this scheme cost height, rate of fault height, maintenance operation cost are higher.Therefore, the coupling of soft start energy-saving, protecting against shock just becomes the goal in research of production and applying unit, Research on transmission mechanism.At present, this type of function coupling has mainly experienced two stages:
One. fluid coupling: this product now is widely used in the transmission field, and its defective is that volume weight is big, compensation and damped tuned characteristic are poor, have slippage, maintenance is very inconvenient, in case overload, the liquid bulging, repair time is very long.
Two. steel ball type soft start coupling: as the emerging one's share of expenses for a joint undertaking of transmission field, it is little that this product has a volume, the advantage of easy care, but there is the low and hard defective of soft start curve of nominal torque validity.
The utility model content
The purpose of this utility model provides a kind of friction type soft start energy-saving safety coupling; under the prerequisite that does not improve original machine power; become a band year startup and be No Load Start; realize the mechanical soft start of prime mover; not only protect prime mover but also save the startup energy consumption, lower the vibratory impulse between working machine and prime mover.
To achieve these goals, the technical solution adopted in the utility model is as follows;
Friction type soft start energy-saving safety coupling, comprise rotor, bearing, bearing (ball) cover and shell, bearing is arranged at the outer surface of rotor, end cap and bearing (ball) cover are coated on bearing surface jointly, and be connected by fastening screw trip bolt, and shell is arranged at the outermost surface of described friction type soft start energy-saving safety coupling, links to each other with end cap by fastening screw trip bolt, it is characterized in that, be provided with friction slip between described rotor and the shell.
Also be provided with extension spring between described friction slip and the rotor.
Described end cap is provided with radiation hole.
Described friction slip is that metallic material is made.
The side of described bearing (ball) cover also is provided with flange, is used for realizing being connected with external equipment.
Working principle of the present utility model: rotor connects by the shaft extension of keyway and prime mover, and rotates with the startup of prime mover, and along with the rotation of rotor, friction slip is resisted the pulling force of extension spring, and fitted with outer casing inner wall gradually under action of centrifugal force; Along with centrifugal force increases gradually, the frictional force of friction slip and outer casing inner wall is also increasing, when frictional force increases to can drive load the time, no longer produces slide relative between friction slip and the shell, and at this moment, prime mover just successfully drives working machine work.
For increasing the service life, on two end caps, be respectively equipped with radiation hole, when rotor rotation, in the can type chamber, form orderly radiating airflow, during overload, can take away friction slip and shell generation slide relative effectively and the heat that produces.
By using coupling described in the utility model, the band that can become working machine carries to start and is No Load Start, thereby reduce prime mover and start Peak current, again because the effect of soft start, working machine is progressively started with the startup of prime mover, not only realize power saving function, also avoided impact shock effectively.
The utlity model has following advantage:
1. power/quality (volume) is than big, and it is convenient to install;
2. the damping characteristic is good, and it is reliable to operate steadily;
3. allow frequent overload, long service life;
4. nominal torque validity height;
5. non-maintaining, when overload took place, just rotor and shell skidded automatically, resumed operation automatically after load is normal, just added bearing grease when normal maintenance and got final product.
6. applied widely, ambient temperature allowed band-40 ℃～+ 150 ℃.
The utility model belongs to a kind of transmission device, is mainly used in the transmission field.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
The corresponding title of label in the accompanying drawing: 1-bearing, 2-end cap, 3-shell, 4-extension spring, 5-friction slip, 6-flange, 7-rotor, 8-bearing (ball) cover.
Embodiment
As shown in drawings, friction type soft start energy-saving safety coupling, comprise rotor 7, bearing 1, end cap 2, bearing (ball) cover 8, shell 3 and flange 6, bearing 1 is arranged at the outer surface of rotor 7, end cap 2 is coated on bearing 1 surface jointly with bearing (ball) cover 8, and be connected by fastening screw trip bolt, and shell 3 is arranged at the outermost surface of described friction type soft start energy-saving safety coupling, link to each other with end cap 2 by fastening screw trip bolt, wherein, also be provided with friction slip 5 between described rotor 7 and the shell 3, friction slip 5 links to each other with rotor 7 by extension spring 4, is respectively equipped with radiation hole on end covers at two sides 2.
All parts all adopt metal to be made in the utility model, and its working procedure is as follows:
At first, outside prime mover starts, driving rotor 7 rotates, the rotation of rotor 7 makes friction slip 5 produce centrifugal force, and centrifugal force increases along with the raising of rotor 7 rotating speeds, friction slip 5 is resisted the pulling force of extension spring 4 under action of centrifugal force, fit with shell 3 inwalls gradually, produces the frictional force that increases gradually between friction slip 5 and the shell 3.When frictional force increases to can drive load the time, no longer produce slide relative between friction slip 5 and the shell 3, at this moment, prime mover just successfully drives working machine and finishes mechanical soft start, reaches the smooth working state.
