Abstract

The utility model relates to an adjustable ball joint. Bushes and a vertical shaft are installed in bracket holes. The bushes are divided into an upper bush and a lower bush, and an adjusting gap is formed between the upper and the lower bushes. The lower bush is an adjustable bush. The lower part of a bracket is provided with an adjustable device and is contacted with the bottom end surface of the lower bush. The gap in the adjustable ball joint can be adjusted at any time, so the service life of the utility model can be prolonged by times compared with an ordinary ball joint under the same working condition. The bushes in the utility model can be changed and can be made of material for powder metallurgy, so as to make the service life of the utility model be further prolonged by more than times or even scores of times. The utility model has the advantage of simple and reasonable structure, convenient and reliable operation, low cost, and stable mechanism running. The utility model is suitable for various machinery equipment, airplanes, ships, steering draw rods of automobiles, swinging devices and loading vertical shaft devices.

Description

Adjustable ball and socket

The utility model relates to the adjustable ball and socket that uses in a kind of machinery, and it is applicable in the steering linkages, oscillator device, load vertical shaft device of various machinery equipments, aircraft, naval vessel, automobile and uses.

Present existing ball-joint is worked in high frequency, than the heavy load situation, and ball-joint easily produces overproof gap, and common ball-joint is not owing to have adjustability, and its working life is shorter, must often change, and increases cost and expense.

The purpose of this utility model provides a kind of adjustable ball and socket that can adjust the ball-joint internal void at any time, and it can overcome existing short shortcoming of ball-joint life-span.

For achieving the above object, technology of the present utility model is: a kind of adjustable ball and socket, comprise vertical shaft, support, lining, lining and vertical shaft are installed in the bracket holes, it is characterized in that lining is divided into upper and lower lining, between the upper and lower lining adjusting play is arranged, following lining is an adjustable buss, and the support bottom is provided with adjusting device and contacts with the bottom end of following lining.

The utility model is owing to adopt said structure, can adjust the gap of ball-joint inside at any time, compare with common ball-joint, under identical working condition, can improve several times working life, its neck bush is replaceable, and material can be selected powder metallurgy, and the ball-joint life-span is increased to more than several times and even tens times again, this product structure advantages of simple, convenient and reliable operation, cost is low, and mechanical operation is stable.
