Technical Field

[0001] The utility model relates to the technical field of textile equipment, in particular to a strip winding machine pulley bearing which is easy to replace. Background Art

[0002] Usually only two sets of narrow bearings are set in the inner hole of the strip winder pulley to connect the driving equipment, and a spacer is used in the middle of the pulley, which significantly reduces the force surface between the bearing and the shaft. The pulley is used to drive the entire body of the car, and a clutch sprocket is installed on the pulley. During operation, the pulley has a high speed and a large load, which causes the pulley bearing to often disengage the main drive shaft from the groove, causing the pulley to swing left and right and wear the clutch teeth, resulting in frequent replacement of the clutch, belt edge running and other problems, making the equipment maintenance workload very large and the material consumption also large.

[0003] In order to prevent the pulley bearing from easily falling out of the groove, causing the pulley to swing during operation, and to facilitate the replacement of the bearing and increase the force-bearing surface between the bearing and the shaft, an easily replaceable strip winder pulley bearing is proposed to solve the above problems.

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0027] See also Figure 1-4 The utility model discloses a strip winding machine pulley bearing which is easy to replace, comprising:

[0028] The mounting shaft 01 is provided on the strip rolling machine in this application;

[0029] A pulley 1, wherein the pulley 1 is sleeved on the mounting shaft 01, and a plurality of connecting bearings 3 are arranged between the pulley 1 and the mounting shaft 01, and the pulley is used to be respectively connected to the power unit and the working shaft of the strip winding machine through a transmission belt;

[0030] The connecting bearing 3 comprises an inner ring 31 and an outer ring 32, two sets of retainers 33 are arranged between the inner ring 31 and the outer ring 32, and multiple sets of rolling bodies 34 are arranged in the two sets of retainers 33. The inner ring 31 and the outer ring 32 are provided with corresponding depressions and protrusions, and the retainers 33 and the rolling bodies 34 are arranged relatively tilted;

[0031] The installation shaft 01 is provided with a seating groove 012 and a plurality of limiting grooves 013 , and the inner ring 31 is provided with limiting protrusions 35 corresponding to the seating groove 012 and the limiting grooves 013 , so as to facilitate the connection and fixation of the bearing 3 .

[0032] It is easy to imagine that the inner ring 31 is connected to the installation shaft 01 through the limiting protrusion 35 and the installation groove 012 and the limiting groove 013 on the installation shaft 01, while the outer ring 32 is connected to the installation hole set at the center of the pulley 1. The pulley 1 and the outer ring 32 are interference connected, or are also connected through the combination of grooves and protrusions.

[0033] In the present application, corresponding depressions and protrusions are provided on the inner ring 31 and the outer ring 32 to form a limiting portion, and the retaining frame 33 and the rolling body 34 are relatively inclined. During the high-speed operation of the pulley 1, when the connecting bearing 3 rotates rapidly, the rolling body 34 will be restricted by the limiting portion between the inner ring 31 and the outer ring 32 and will not easily fall out, thereby avoiding the deviation of the pulley bearing. At the same time, multiple sets of connecting bearings 3 are provided, which can effectively increase the force area between the bearing of the pulley 1 and the shaft, thereby improving the stability of the pulley 1 during operation.

[0034] It should be further explained that the multiple limit grooves 013 are arranged perpendicular to the receiving grooves 012, and the number of the connecting bearings 3 and the receiving grooves 012 is four groups, wherein the direction in which the limit grooves 013 are arranged relative to the receiving grooves 012 is consistent with the rotation direction of the pulley 1, so that when the pulley 1 rotates, the connecting bearing 3 is driven by the pulley 1 so that the limit protrusion 35 is inserted into the limit groove 013, thereby limiting the connecting bearing 3.

[0035] In the present application, a limit ring 011 is provided on the installation shaft 01, and a thread 014 is also provided on the installation shaft 01. The installation shaft 01 is threadedly connected to the limit knob 2 through the thread 014, and the limit knob 2 and the limit ring 011 are used to contact and limit the inner ring 31 of the connected bearing 3.

[0036] In the above, each connecting bearing 3 can be limited and fixed by the above-mentioned limit knob 2 and the limit ring 011. When the connecting bearing 3 needs to be removed, the limit knob 2 can be removed, and then the pulley 1 is rotated in the opposite direction. The friction between the pulley 1 and the connecting bearing 3 drives the limit protrusions 35 on the multiple connecting bearings 3 to disengage from the limit groove 013 and arrange them in a straight line in the placement groove 012, so as to facilitate the removal of the pulley 1 as a whole for subsequent maintenance and care.

[0037] like Figure 3 As shown, the inner ring 31 and the outer ring 32 are provided with concave and convex cross-sections in a truncated cone shape, and the rolling bodies 34 are provided on both sides of the truncated cone to limit the positions thereof and to support the inner ring 31 and the outer ring 32 .

[0038] Finally, it should be added that the limit knob 2 and the limit ring 011 are both provided with connecting gaskets on one side relative to the connecting bearing 3. Since the connecting bearing 3 will be affected by vibration when the pulley 1 rotates rapidly, in order to avoid the limit knob 2 from loosening due to vibration and to avoid damage to the connecting bearing 3, a connecting gasket is provided for reinforcement.

[0039] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back...), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0040] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the utility model, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or suggesting their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the utility model.

[0041] In addition, "plurality" means two or more.

[0042] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
