Problems solved by technology

However, during the movement of the equipment along the screw, when there is a load on the mobile equipment, the effect of the force is decomposed into positive pressure and eccentricity. These forces act on the nut fixed on the mobile equipment. The eccentricity makes the nut and the screw Uneven direct force will intensify the friction between the screw and the nut, and even the nut and the screw will get stuck, which will affect the life of the screw and the use of the equipment

Embodiment 1

[0024] Such as Figure 1-5 As shown, a universal mechanism 10 for adjusting the eccentricity of the screw includes an inner plate 1 and an outer plate 2, the inner plate is provided with a central through hole 1.1 formed therein, and a pair of inner bushings 1.2 are provided outside the inner plate, The inner shaft sleeve is parallel to the plane of the inner plate, and the inner shaft sleeve 1.2 is covered with a ball bearing 1.3, which is connected with the inner shaft sleeve cavity 2.3 through the ball bearing 1.3 to reduce friction and shaking between the inner shaft sleeve and the inner shaft sleeve cavity.

[0025] The outer plate 2 is connected by two transverse connecting plates 2.1 and two longitudinal connecting plates 2.2 to form a rectangular structure. The transverse connecting plate 2.1 has an inner bushing cavity formed therein, and the outer side of the longitudinal connecting plate 2.2 is provided with an outer bushing. The two ends of the longitudinal connect...

Abstract

The invention discloses an omnidirectional mechanism for adjusting the eccentricity of a screw. The mechanism comprises an inner plate and an outer plate, wherein the inner plate is provided with a center through hole formed in the center of the inner plate, a pair of inner shaft sleeves is arranged on the outer side of the inner plate and parallel to the plane of the inner plate, a cavity for accommodating the inner plate is formed in the outer plate, the body of the outer plate is provided with a pair of outer shaft sleeves and a pair of inner shaft sleeve cavities, the center axis of the outer shaft sleeves intersects with the center axis of the inner shaft sleeve cavities in the same plane, the inner shaft sleeve is sleeved with the inner shaft sleeve cavity, and the inner shaft sleeve rotates freely in the inner shaft sleeve cavity; the inner plate is connected with the outer plate through the inner shaft sleeves, and the inner plate can rotate along the axis of the inner shaft sleeves; meanwhile, the outer plate is connected with other structures through the outer shaft sleeves, and the whole outer plate can rotate along the axis of the outer shaft sleeves to achieve omnidirectional adjustment.

Description

technical field [0001] The invention relates to a universal mechanism for adjusting the eccentricity of a screw rod. Background technique [0002] The screw is an ideal product for converting rotary motion into linear motion, or converting linear motion into rotary motion, and is used in various industries. However, during the movement of the equipment along the screw, when there is a load on the mobile equipment, the effect of the force is decomposed into positive pressure and eccentricity. These forces act on the nut fixed on the mobile equipment. The eccentricity makes the nut and the screw The direct force is uneven, which intensifies the friction between the screw and the nut, and even the nut and the screw are stuck, which affects the life of the screw and the use of the equipment. Contents of the invention [0003] One of the purposes of the present invention is to provide a universal mechanism for adjusting the eccentricity of the screw, which can realize the univ...
