Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of spinning spindle bearing, concretely relates to a novel spinning spindle bearing. BACKGROUND

[0002] The spinning spindle bearing is a bearing for being installed on a spinning spindle, the spinning spindle is one of main components for twisting and winding on a spinning machine, and is usually a combined component with an elongated rotary shaft supported by two points as a main body. In a spinning process, the spindle drives a ring to move on a ring raceway through high-speed rotation, twists a fiber bundle after drafting to make the fiber bundle have a certain strength, and winds the fiber bundle on a bobbin sleeved on the spindle, so that a yarn is finally formed. In order to meet the quality requirements of spinning, the spinning spindle needs to meet requirements such as high speed, stability, wear resistance, energy saving and the like, and the present application provides a novel spinning spindle bearing.

[0003] The existing spinning spindle bearing adopts a common cylindrical roller as a rolling body, the bearing structure is relatively complex, the cost is relatively high, the friction and wear are fast due to a large contact surface, the high-speed running performance is limited, the energy consumption is high, and the like, which leads to shortening of the service life of the spinning spindle and the need for regular replacement.

[0004] Therefore, the utility model provides a novel spinning spindle bearing to solve the above problems. UTILITY MODEL CONTENTS

[0005] In order to solve the above technical problems, the utility model provides a novel spinning spindle bearing to solve the problems that the existing spinning spindle bearing adopts a common cylindrical roller as a rolling body, the bearing structure is relatively complex, the cost is relatively high, the friction and wear are fast due to a large contact surface, the high-speed running performance is limited, the energy consumption is high, and the like, which leads to shortening of the service life of the spinning spindle and the need for regular replacement.

[0006] A novel spinning spindle bearing, comprising a bearing outer ring, a retainer is arranged in the bearing outer ring, and a ball is embedded in the retainer, and the bearing outer ring, the retainer and the ball constitute a spinning spindle bearing without an inner ring.

[0007] Preferably, one or more circular-arc-shaped grooves arranged in a ring shape are arranged on the inner wall of the bearing outer ring.

[0008] Preferably, one or more pockets arranged in a ring shape are arranged on the retainer, the pocket is spherical, the diameter of the pocket is slightly larger than the diameter of the ball, and the window of the pocket is smaller than the diameter of the ball. Because the retainer has a certain elasticity, when the ball is embedded in the pocket from the window of the retainer, the position of the ball can be relatively fixed, and the ball can move flexibly at the same time.

[0009] Preferably, the ball is a steel ball or a ceramic ball.

[0010] Preferably, the inner tangent circle formed after the rolling balls embedded in the cage are arranged in a ring shape has a diameter slightly larger than the diameter of the spindle.

[0011] Compared with the prior art, the novel spindle bearing has the following beneficial effects:

[0012] The inner tangent circle formed after the rolling balls embedded in the cage are arranged in a ring shape has a diameter slightly larger than the diameter of the spindle, so that the spindle can be quickly inserted into the bearing, and when the spindle is inserted into the bearing, the spindle can keep a stable rotation in the bearing. The bearing has the advantages of simple structure, low cost, small friction and wear, high rotation speed and low energy consumption. If the rolling balls are replaced by ceramic balls, the bearing has better wear resistance. BRIEF DESCRIPTION OF DRAWINGS

[0018] The embodiments of the present application will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate the present application, but cannot be used to limit the scope of the present application.

[0019] As shown in Figures 1-2 The present application provides a novel spindle bearing, which comprises a bearing outer ring 1, a cage 2 arranged inside the bearing outer ring 1, and rolling balls 3 embedded in the cage. The bearing outer ring 1, the cage 2 and the rolling balls 3 form a spindle bearing without an inner ring. When the spindle is inserted into the bearing, the spindle can keep a stable rotation in the bearing.

[0020] The inner wall of the bearing outer ring 1 is provided with one or more circular arc grooves arranged in a ring shape.

[0021] The cage 2 is provided with one or more annularly arranged pockets, which are spherical and have a diameter slightly larger than that of the ball but a window smaller than that of the ball.

[0022] The ball 3 is a steel ball or a ceramic ball, which has a lighter weight, a higher hardness and a stronger wear resistance, can adapt to a higher speed, and has a slightly higher cost but a higher cost performance.

[0023] The diameter of the inscribed circle formed after the ball 3 is embedded in the annularly arranged pockets of the cage is slightly larger than that of the spindle, so that the spindle can be quickly inserted or pulled out and a stable rotation of the spindle can be ensured.

[0024] Embodiment two, referring to the attached Figure 3 、 4 Different from the embodiment one, the ball 3 is provided with two circles.

[0025] Working principle: the cage 2 is put into the bearing outer ring 1, and then the ball 3 is embedded in the pocket from the window of the cage 2 until each pocket is filled with the ball 3, at this time, the spinning bearing forms an integral whole. After the spinning bearing is assembled on the spinning spindle, the spindle can be inserted into the ball 3, so that a stable rotation of the spindle can be ensured.

[0026] The embodiments of the present application are given for the purpose of illustration and description, although the embodiments of the present application have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as a limitation of the present application, and those skilled in the art can change, modify, replace and modify the above embodiments within the scope of the present application.
