Abstract
The utility model relates to an axial positioning device for running wheels of hoisting machinery. Negative situations that the running wheels carry out rail gnawing along the rails and blocked in the rails are caused by structural deformation of the hoisting machinery and the problem of degree of parallelism of running rail paving. Therefore, the axial positioning device for the running wheels of the hoisting machinery comprises a hoisting machinery running end beam and the running wheels, wherein the hoisting machinery running end beam is provided with a threaded stepped wheel shaft; the stepped wheel shaft is provided with two bearings; the two bearings are positioned inside wheel hubs of the running wheels; two T-shaped locating sleeves which are used for adjusting the positions of the bearings and play a role in sealing are arranged outside the two bearings; an adjustable locating round nut matched with thread on the stepped wheel shaft is arranged outside each T-shaped locating sleeve. The axial positioning device is scientific in design, and the problems that the running wheels carry out rail gnawing along the rails and blocked in the rails are solved, so that running safety of the hoisting machinery is improved.
Description
Technical field
The utility model relates to a kind of axial direction positioning device, particularly a kind of elevator machinery operation wheel axial direction positioning device.
Background technology
At present, elevator machinery is the elevator machinery of the field widespread uses such as China industrial and mining enterprises, steel chemical, railway traffic, port and pier, in national product, occupies important position.In the production process of elevator machinery, due to the operation end carriage, generally adopt the case structure of welding, so inevitably can produce the problem on deformation of dependency structure, the planeness of laying due to the elevator machinery orbit again simultaneously there are differences, later stage will cause the negative condition such as rail, elevator machinery wheel and track be stuck of gnawing of elevator machinery operation wheel orbiting direction, has fatal risk in the elevator machinery operational process.
Summary of the invention
Technical problem to be solved in the utility model is for overcoming because structure fabrication distortion and the orbit of elevator machinery are laid the Orbiting stuck negative condition of rail, elevator machinery wheel and track of gnawing of operation wheel that the planeness problem is brought, increase the life-span of wheel and track, reduce wheel and track fault rate, improve the overall security of elevator machinery.
The technical problems to be solved in the utility model is the above-mentioned defect that how to overcome prior art, a kind of elevator machinery operation wheel axial direction positioning device is provided, and this elevator machinery operation wheel axial direction positioning device has improved the Orbiting stuck negative condition of rail, elevator machinery wheel and track of gnawing of elevator machinery operation wheel greatly.
For solving the problems of the technologies described above, this elevator machinery operation wheel axial direction positioning device, comprise elevator machinery operation end carriage and operation wheel, on elevator machinery operation end carriage, threaded notch cuttype axletree is installed, two bearings are installed on the notch cuttype axletree, and two bearings are positioned at the operation wheel wheel hub; Between two bearings, be provided with the bearing spacer, the external diameter of bearing spacer and the inner ring of bearing match; Two bearing outsides are provided be used to the position of adjusting bearing and two T-shaped locating bushs with sealing function, and the horizontal area of bed of T-shaped locating bush matches with bearing inner ring, and vertical area of bed of T-shaped locating bush matches with the operation wheel wheel hub; Each T-shaped locating bush outside is equipped with the adjustable setting circle nut matched with screw thread on the notch cuttype axletree, and the setting circle nut is separately positioned on the operation wheel both sides.
So design, by adjusting the setting circle nut, both can when bearing is installed, avoid directly clashing into bearing and affect bearing life, can carry out the axial location operation wheel by the position of adjusting circular nut simultaneously, greatly improve the Orbiting stuck negative condition of rail, elevator machinery wheel and track of gnawing of elevator machinery operation wheel.
As optimization, two bearings, two T-shaped locating bushs and two setting circle nuts are mirror-image structure.So design, be convenient to processing and install, and easy to use.
The utility model elevator machinery operation wheel axial direction positioning device, simple in structure, design science, easy to use, the parallelism problem solved due to elevator machinery structural distortion and the laying of elevator machinery orbit causes the Orbiting stuck negative condition of rail, elevator machinery operation wheel and track of gnawing of overhead traveling crane machinery operation wheel, has greatly increased the safety of elevator machinery operation.Have actual application value and promotional value preferably.
