Abstract
The utility model belongs to a coupling transmission device between mechanical shafts and particularly relates to a coupler for mechanical equipment such as a pump, a reducer, a mine and the like. The coupler adopts the structure that a driven shaft and a driving shaft are installed in a left shaft sleeve and a right shaft sleeve respectively, the shafts and the shaft sleeves on the two sides are connected through keys, a series of power transmission gears are uniformly distributed at the outer circumferences of the left shaft sleeve and the right shaft sleeve, elastic sheets are inserted in the tooth spaces among the power transmission gears, and the elastic sheets are arranged in a housing. The coupler has the characteristics of simplicity in structure, convenience in disassembly, shaft deviation prevention, impact resistance, dust prevention, good vibration attenuation and long service life.
Description
Technical field
The utility model belongs to the connection transmission device between mechanical axis, especially for the coupling of machinery such as pump, speed reducer, mine.
Background technique
Can pump be the most frequently used equipment for liquid transportation, and the reliability of pump is the most basic requirement, be exactly manufacturing eternal pursuit so guarantee its reliability.Because the operating mode of pump is more complicated all, be embodied in: dust impurity is many and kind is many, and pump coupler partly cooperates requirement higher relatively, so just must consider that protection equipment guarantees its reliability; Pump uses many in factories such as chemical enterprise and waste water treatments, and with pump circumstance complication, danger, therefore has the situation of keeping in repair and observing of being not easy to, and guarantees that like this reliability is just particularly important; In general the power of motor all is can not off-rating; but in the utilization process of reality owing to electrical network or owing to reasons such as mechanical failures; often have the overload phenomenon; cause the link position of pump and motor to bear very big impact; and general coupling is difficult to bear this impact; often break down, cause equipment can't carry out daily production normally.
Summary of the invention
The purpose of this utility model provides a kind of improved coupling, is convenient to dismounting, has to prevent axle deflection, prevent to impact and the dust-tight characteristics, and vibration damping is good, long service life.
The purpose of this utility model is achieved through the following technical solutions: be respectively charged into driven shaft and driving shaft in left and right axle sleeve, by key the axle of both sides is linked together with axle sleeve, the excircle of left and right axle sleeve is to being evenly equipped with a series of power transmission teeth, be inserted with spring sheet in the backlash between the power transmission tooth, spring sheet goes into to have among the case outward.
Described spring sheet becomes in the backlash of the reciprocal snakelike power transmission tooth of packing into, and seal ring is equipped with in the annular contact surface position between case both sides and the left and right axle sleeve.
The cross section of spring sheet is trapezoidal, and the power transmission tooth is the cambered surface tooth, and spring sheet is two sections of the semi-circlees of corresponding case, and the two halves round casing of case for separating connects into round casing with bolt.
The beneficial effects of the utility model:
1. vibration damping is good, long service life.Since the effect of spring peripheral force, the resiliently deformable that spring is produced when transmitting torque, and effectiveness in vibration suppression has been played in the distortion of spring simultaneously of can avoiding resonating; The spring sheet of trapezoid cross section adopts the spring steel of high-quality, forms through special processing and heat treatment, and it has the favorable mechanical performance, and the life-span is guaranteed
2. simple in structure, convenient disassembly.Machine part is few, volume is little, in light weight.The case of two halves and spring sheet make dismounting, the maintenance more more convenient than general coupling.
3. allow bigger installation deviation.Because spring sheet and sector face are surface of contact, so that coupling can obtain bigger flexiblely, it can be when mounted radially, angle, axially proper functioning under the deviation situation occurs.
Description of drawings
Below in conjunction with accompanying drawing and enforcement the utility model is further described.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the schematic appearance of half case of dismounting of the present utility model.
Among the figure: driven shaft 1, key 2, axle sleeve 3, spring sheet 4, key 5, axle sleeve 6, driving shaft 7, screw 8, seal ring 9, case 10, bolt 11, seal ring 12, screw 13, power transmission tooth 14.
Embodiment
As shown in the figure, in left and right axle sleeve 3 and 6, be respectively charged into driven shaft 1 and driving shaft 7, by key 2,5 axle of both sides is linked together with axle sleeve, axle sleeve 3 and 6 excircle are to being evenly equipped with a series of power transmission teeth 14, the serpentine spring sheet 4 of reciprocating and turning-back is inserted in the backlash between the power transmission tooth 14, spring sheet 4 is the snakelike of two semi-circlees, be trapped among the periphery of axle sleeve 3,6, among being covered on by the case 10 in two halves garden, seal ring 12 and 9 are equipped with in the annular contact surface position between case 10 both sides and left and right axle sleeve 3 and 6 again.The cross section of spring sheet 4 is trapezoidal, and power transmission tooth 14 is the cambered surface tooth, and spring sheet 4 can have certain freely swinging, rotate and float at the power transmission between cog of axle sleeve, and a kind of eccentric permission is provided.Case 10 can prevent that dust and some Korrosionsmediums from entering in the coupling, has effectively played the effect of protection and sealing, has guaranteed the reliability under bad working environments.
Claims (3)
1. a coupling is respectively charged into driven shaft and driving shaft in left and right axle sleeve, it is characterized in that: the excircle of left and right axle sleeve is inserted with spring sheet to being evenly equipped with a series of power transmission teeth in the backlash between the power transmission tooth, and spring sheet goes into to have among the case outward.
2. coupling according to claim 1 is characterized in that: spring sheet becomes in the backlash of the reciprocal snakelike power transmission tooth of packing into, and seal ring is equipped with in the annular contact surface position between case both sides and the left and right axle sleeve.
3. coupling according to claim 2 is characterized in that: the cross section of spring sheet is trapezoidal, and the power transmission tooth is the cambered surface tooth, and spring sheet is two sections of the semi-circlees of corresponding case, and the two halves round casing of case for separating connects into round casing with bolt.
