Specific embodiment
With reference to the accompanying drawings and examples, specific embodiment of the present utility model is described in further detail.With
Lower specific embodiment is not intended to limit the scope of the present invention for illustrating the utility model.
It is in the description of the present invention, it should be noted that term " center ", "upper", "lower", "left", "right", " perpendicular
Directly ", the orientation or positional relationship of the instructions such as "horizontal", "inner", "outside" is to be based on the orientation or positional relationship shown in the drawings, and is only
For ease of description the utility model and simplify description, rather than the device or element of indication or suggestion meaning must have it is specific
Orientation, with specific orientation construction and affected, therefore should not be understood as limiting the present invention.
In the description of the present invention, it should be noted that unless otherwise clearly defined and limited, term " is pacified
Dress ", " connected ", " connection " shall be understood in a broad sense, for example, it may be being fixedly connected, may be a detachable connection, or integrally
Connection；Can be mechanical connection, be also possible to be electrically connected, can be directly connected, can also indirectly connected through an intermediary,
It can be the connection inside two elements.For the ordinary skill in the art, above-mentioned art can be understood with concrete condition
The concrete meaning of language in the present invention.
Height limitator is also hoisting limiter, is the advanced safety guard for limiting lifting altitude, fits
For all kinds of cranes.
Concentricity is exactly alignment tolerance, and theoretical correct position is datum axis.Since tested axis is to datum axis
Difference may occur in all directions of space, therefore its tolerance range is one using datum axis as the cylindrical body of axis, tolerance value
For the diameter of the cylindrical body.Two axis on the same line are required on part, and much journeys have occurred between two axis
The deviation of degree, when datum axis is ideal straight line, the deviation of two axis is usually the synthesis of three kinds of situations, i.e., tested axis is curved
The synthesis of bent, tested axis inclination and tested axis offset.
Coaxality measurement generally use concentricity prover measure, with three coordinates carries out concentricity detection intuitively, conveniently,
Measurement result precision is high, and reproducible.The principal element for influencing concentricity has the center location of tested element and base element
And axis direction, two section circles of measurement, make reference axis with its line such as on benchmark cylinder.Two are also measured on tested cylinder
A section circle, constructs straight line, then calculates concentricity.Concentricity need to be maintained at certain margin of tolerance.
Even if installation is horizontal higher, concentricity has only obtained a degree of guarantee, complete coaxial in absolute sense
It can not achieve, in the connection type of Present Attitude limiter and hoist reduction gear, height limitator passes through with retarder needs
Solid shafting is attached, and needs to guarantee the concentricity between axis, and difficulty is larger.Concentricity is lower, will affect the normal of equipment
Work and service condition, situations such as equipment generation vibration, damage of components can be made and worn, shadow when especially equipment runs at high speed
Sound is larger.
