Problems solved by technology

[0002] At present, the mechanical device that converts circular motion into reciprocating translational motion generally adopts cam mechanism. The design of the contour shape of the cam can indeed obtain the required stroke and motion track, but the friction of the cam mechanism is large, and the movement when the mass of the lifting part is large The inertia is large, and the lifting part tends to break away from the contact of the cam when turning, and the motion trajectory is inaccurate; if a spring is used to apply thrust to improve the accuracy of the motion trajectory, the resistance of the cam will be increased for no reason, wasting energy consumption
Moreover, the cam mechanism has defects such as high manufacturing cost, fast wear, insufficient precision, and short service life.

Embodiment 1

[0027] The structure of double-row double-rod bearings for vibration machinery is as follows: Figure 1 to Figure 5 As shown, the outer ring 2 is obliquely placed on the inner ring 1, and the steel balls 3 and the cage 4 are installed in the outer ring 2, and the uniformly distributed steel balls 3 are pressed against the outer ring groove 2-1 of the outer ring and the inner ring The inner ring groove 1-1.

[0028] The axis of the outer ring groove 2-1 is not parallel to the axis of the inner ring through hole 1-2, and the intersection angle in this embodiment is 9.6 degrees.

[0029] In this embodiment, there are two cylindrical rods 2-2 arranged symmetrically; the number, position and length of the cylindrical rods 2-2 can be arbitrarily set according to the needs of the equipment.

[0030] Such as Figure 4 As shown, two inner ring grooves 1-1 with circular arc bottoms are arranged in parallel on the outer wall of the inner ring 1 in this embodiment, and several outer rin...

Embodiment 2

[0033] Such as Figure 6 The shown single-row double-rod bearing has the same basic structure as that of Embodiment 1, except that a stepped through hole 1-2 is provided in the middle of the inner ring 1 for installing shaft parts that transmit torque; and the double-row steel balls are reduced to One row, suitable for equipment with lighter loads, because the manufacturing difficulty is greatly reduced, so the cost is low.

Embodiment 3

[0035] Such as Figure 7 The shown single-row single-rod bearing has the same basic structure as that of Embodiment 2, except that only one cylindrical rod is provided on the outer ring, which lowers the manufacturing cost and is suitable for common equipment such as electric hammers.

Abstract

The invention relates to a special bearing suitable for the oscillating machinery, such as fluid equipment, an electric hammer such as. The special bearing comprises an inner ring, an outer ring, a steel ball and a retainer, wherein the outer wall of the middle section of the inner ring is spherical and is provided with an annular groove; the circular arc of the groove is adaptive to the external diameter of the steel ball; the axis of the annular groove is not parallel to the axis of an inner-ring through hole; an crossing angle between the axis of the annular groove and the axis of the inner-ring through hole is 8-82 degrees; the inner circle of the outer ring is provided with an annular groove; the outer wall of the outer ring is radially provided with a plurality of cylindrical bars; the steel ball tightly contacts with the annular groove on the outer wall of the inner ring and the annular groove on the inner circle of the outer ring; thereby, the inner ring can easily rotate in the outer ring; and if the cylindrical bars are provided with slideways parallel to the axis of the inner ring, the inner ring rotates to drive the cylindrical bars of the outer ring to carry out reciprocating translation in the slideways so as to drive equipment components to frequently oscillate. According to the requirement, the special bearing can be set into various combined bearings, such as double rows, double bars such as. The special bearing suitable for the oscillating machinery has a compact mechanism, little radiation after being continuously used and energy consumption saving, and is easy to operate.

Description

technical field [0001] The invention relates to the field of mechanical manufacturing, in particular to special bearings suitable for vibrating machines such as robots, electric hammers, fluid equipment, and spraying equipment. Background technique [0002] At present, the mechanical device that converts circular motion into reciprocating translational motion generally adopts cam mechanism. The design of the contour shape of the cam can indeed obtain the required stroke and motion track, but the friction of the cam mechanism is large, and the movement when the mass of the lifting part is large The inertia is large, and when turning, the lifting parts tend to break away from the contact of the cam, and the motion trajectory is inaccurate; if a spring is used to apply thrust to improve the accuracy of the motion trajectory, the resistance of the cam will be increased without reason, and energy consumption will be wasted. Moreover, the cam mechanism also has defects such as hig...
