Description

Technical Field

[0001] This utility model relates to the field of spinning machine technology, and in particular to a bearing seat for a spindle tension device. Background Technology

[0002] The spinning machine is a crucial piece of equipment in the textile industry's production process, affecting a large number of products. Its performance directly impacts yarn quality, labor requirements, workers' workload, management efficiency, and economic benefits. The level of spinning machine quality directly influences the development of the cotton spinning industry.

[0003] With the upgrading of the textile industry, users have increasingly higher requirements for textile machinery. Long spinning machines with collective doffing have become the mainstream in the market today. In order to adjust the tension of the spindle belt, a spindle belt tensioning device is generally required. The tensioning device can adjust the tension of the spindle belt, but because the spindle belt is in a twisted state during the winding process, it is difficult for the spindle belt to keep in close contact with the tensioning device, resulting in poor stress state of the spindle belt and easy slippage or detachment. Utility Model Content

[0004] The technical problem to be solved by this utility model is: In order to solve the technical problems in the prior art, this utility model provides a bearing seat for a belt tensioning device.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a bearing seat for a spindle tension device, including a seat body, wherein the seat body is provided with a mounting groove for accommodating the bearing, the mounting groove is arc-shaped so that the bearing can be inserted into the mounting groove radially, and the central angle of the mounting groove is greater than 180 degrees.

[0006] The bearing housing of this utility model for a belt tensioning device features a radial snap-fit ​​design between the bearing and the mounting groove, making installation convenient, reducing labor time, and facilitating maintenance. The bearing housing is made of plastic and manufactured using a mold-forming process, resulting in lower production costs for mass production. Furthermore, the central angle of the mounting groove is greater than 180 degrees, requiring temporary deformation of the housing body to allow the bearing to snap into place. After the bearing is snapped in, the housing body also provides radial restraint for the bearing.

[0007] Furthermore, the wall of the mounting groove is arc-shaped or planar along the axial direction of the mounting groove. When the wall of the mounting groove is arc-shaped along the axial direction of the mounting groove, it facilitates the swinging of the seat relative to the bearing; when the wall of the mounting groove is planar along the axial direction of the mounting groove, it facilitates the installation of a planar bearing.

[0008] Furthermore, a limiting protrusion is provided on the side wall of the mounting groove, and the bearing is located between the limiting protrusion and the end of the mounting groove.

[0009] Furthermore, a weight-reducing groove is provided on the side wall of the mounting groove.

[0010] Through the above solution, the weight reduction groove can not only reduce the weight of the seat, but also provide ventilation and heat dissipation for the bearing during operation.

[0011] Furthermore, multiple weight-reducing grooves are provided along the circumference of the mounting groove.

[0012] Furthermore, the end of the weight-reducing groove away from the limiting protrusion is disposed through the base body.

[0013] Furthermore, the base is provided with a limiting block that cooperates with the bearing, and the bearing is provided with two limiting pins along its circumference, with the limiting block located between the two limiting pins.

[0014] Furthermore, the seat body is provided with a positioning block that cooperates with the tension structure.

[0015] Furthermore, the base is provided with mounting countersunk holes for connection with the tension structure.

[0016] Furthermore, the side wall of the seat is provided with reinforcing ribs.

[0017] The beneficial effects of this utility model are:

[0018] 1. The installation slot and bearing can be radially snapped together, which makes installation more convenient, reduces labor time, and makes maintenance more convenient. At the same time, the bearing housing is made of plastic material and manufactured through mold forming process, which reduces the cost of mass production.

[0019] 2. By setting the mounting groove in an arc shape, the seat can swing and deflect at a certain angle relative to the bearing, thus achieving self-adjustment. This allows the tension structure installed on the bearing seat to swing, making it easier for the tension structure to adapt to the torsional state of the spindle belt and reducing the possibility of the spindle belt slipping or falling off.

[0020] 3. By setting the limit block and limit pin, it is easy to limit the angle of the seat body swinging around the bearing circumference, prevent the tension structure from naturally drooping clockwise and counterclockwise after the spindle strip falls off, and when installing the spindle strip, it is easy to install the spindle strip from a close angle, reducing installation time and saving the time to reinstall the spindle strip after it falls off during maintenance.

[0021] 4. The weight-reducing groove helps save materials and reduces the contact area between the mounting groove and the bearing, thereby improving the stability of the bearing and housing fit. Attached Figure Description

[0028] This utility model discloses a bearing seat for a belt tensioning device.

[0029] Reference Figure 1 and Figure 2A bearing housing for a strip tensioning device is disclosed, used to install a tensioning structure 3. It includes a housing 1, with reinforcing ribs 11 fixedly connected to the side wall of the housing 1. The housing 1 has a mounting groove 12 for accommodating a bearing 2. The groove wall of the mounting groove 12 is either arc-shaped or planar. When the groove wall of the mounting groove 12 is arc-shaped along the axial direction of the groove, it facilitates the installation of spherical bearings and allows the housing 1 to swing relative to the bearing. When the groove wall of the mounting groove 12 is planar along the axial direction of the groove, it facilitates the installation of planar bearings. The arc-shaped mounting groove 12 allows the housing 1 to swing relative to the bearing 2, thus enabling the tensioning structure 3 mounted on the bearing 2 to swing, thereby adapting to the torsional state of the strip and reducing the possibility of the strip slipping or falling off.

[0030] Specifically, the mounting groove 12 is arc-shaped so that the bearing 2 can be radially engaged with the mounting groove 12, and the central angle of the mounting groove is greater than 180 degrees. The radial engagement between the mounting groove and the bearing facilitates installation, reduces labor time, and makes maintenance easier. The housing 1 is made of plastic and manufactured using a molding process, resulting in lower production costs for mass production. The greater than 180-degree central angle of the mounting groove 12 requires temporary deformation of the housing 1 to engage the bearing 2. After engagement, the housing 1 also provides radial restraint for the bearing 2. A restraining protrusion 13 is integrally formed on the side wall of the mounting groove 12. The bearing 2 is located between the restraining protrusion 13 and the end of the mounting groove 12. The restraining protrusion 13 prevents the housing 1 and bearing 2 from separating axially while maintaining radial assembly of the bearing 2 along the mounting groove 12. This design ensures reliable axial restraint between the bearing 2 and the housing 1 while facilitating assembly.

[0031] Furthermore, a weight-reducing groove 14 is provided on the side wall of the mounting groove 12, with multiple weight-reducing grooves 14 arranged circumferentially along the mounting groove 12. The weight-reducing groove 14 helps save material and reduces the contact area between the mounting groove 12 and the bearing 2, thereby improving the stability of the fit between the bearing 2 and the housing 1. The end of the weight-reducing groove 14 furthest from the limiting protrusion 13 penetrates through the housing 1, facilitating the machining of the weight-reducing groove 14.

[0032] It should be noted that the base 1 has an integrally formed limiting block 17 that mates with the bearing 2. The bearing 2 has two limiting pins 21 connected along its circumference, and the limiting block 17 is located between the two limiting pins 21. The setting of the limiting block 17 and the limiting pins 21 makes it easy to limit the angle of swing of the base 1 along the circumference of the bearing 2, preventing the tension structure 3 from naturally drooping clockwise and counterclockwise after the spindle strip falls off. Moreover, when installing the spindle strip, it is easy to install the spindle strip from a near angle, reducing installation time and saving time when the spindle strip falls off during maintenance.

[0033] In addition, the base 1 is provided with a positioning block 15 that cooperates with the tension structure 3, and the base 1 is also provided with a mounting countersunk hole 16 for connecting with the tension structure 3.

[0034] It should be noted that bearing 2 can be a planar bearing with a cylindrical surface or a spherical bearing with a UC20 series surface.

[0035] Working principle: Due to the arc-shaped setting of the mounting groove 12, the seat 1 can swing relative to the bearing 2, which allows the tension structure 3 installed on the bearing 2 to swing, thereby adapting to the torsional state of the spindle belt and reducing the possibility of the spindle belt slipping or falling off.

[0036] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
