Description

Technical Field

[0001] This utility model specifically relates to the technical field of spinning machine accessories, and more specifically to a highly reliable bridge gear shaft assembly. Background Technology

[0002] The bridge gear shaft assembly is a key component in the transmission system of a spinning machine. It mainly consists of a bridge gear shaft, a bridge gear, bearings, keys, washers, bolts, etc. The bridge gear shaft assembly is the core component of the transmission system, mainly used to transmit power, change speed and direction, and ensure the coordinated operation of various components of the spinning machine (such as rollers, spindles, and skin rollers) to achieve stable spinning process.

[0003] The power source of a spinning machine (such as a motor) is usually located at one end of the frame. The bridge gear shaft assembly transmits power "across" a certain distance to other key components (such as the front roller, middle roller, and rear roller) through gear meshing, avoiding the structural limitations of direct transmission.

[0004] However, in practice, it has been noted that when a spinning machine is in use, the gears on the bridge gear shaft need to rotate at high speed for a long time. This causes the gears to deviate laterally during rotation, which affects the power transmission of the gears and thus affects the normal use of the spinning machine. Utility Model Content

[0005] The purpose of this invention is to provide a highly reliable bridge gear shaft assembly. By utilizing rolling stabilizers on both sides of the bridge gear to restrict its position, the lateral slippage of the bridge gear during prolonged rotation is prevented, thereby improving the stability of the bridge gear during use and increasing the reliability of the bridge gear shaft assembly. This addresses the technical problems mentioned in the background section.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A highly reliable bridge gear shaft assembly includes an auxiliary bracket, a V-shaped bracket welded to the side of the auxiliary bracket, and a fixed shaft rod fixedly connected in a rectangular array at the end of the V-shaped bracket away from the auxiliary bracket.

[0008] The fixed shaft includes a support shaft that is fixedly connected to the V-shaped frame. A bridge gear and a rolling stabilizer are respectively installed on the support shaft, and an end stop is fixedly connected to the end of the support shaft away from the V-shaped frame.

[0009] As a further technical solution of this utility model, the rolling stabilizer includes retaining rings located on both sides of the bridge gear. The retaining rings are provided with spherical slots in a ring array, and each of the spherical slots is fitted with a stabilizing ball.

[0010] As a further technical solution of this utility model, the end stop includes a limiting stop plate that fits against the end of the support shaft, and the limiting stop plate has a limiting groove on the side near the support shaft, and a fixing bolt is fitted through the limiting stop plate.

[0011] As a further technical solution of this utility model, the end of the support shaft is provided with a threaded fixing hole, and the fixing bolt passes through the support shaft and is threadedly engaged with the threaded fixing hole.

[0012] As a further technical solution of this utility model, the end of the support shaft is provided with symmetrical limiting slots, and the side of the limiting plate is integrally provided with a positioning block corresponding to the limiting slot, and the positioning block is inserted and engaged with the limiting slot.

[0013] As a further technical solution of this utility model, the stabilizing balls are respectively attached to the V-shaped frame and the bridge gear, as well as the bridge gear and the limiting plate on both sides, and the bridge gear and the supporting shaft are interference-fitted with a movable bearing.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] In this invention, when the bridge gear rotates on the support shaft, the stabilizing balls on both sides of the bridge gear will roll along with the bridge gear. The stabilizing balls on both sides ensure the stability of the bridge gear during rotation, prevent the bridge gear from axial movement, and the rolling stabilizing balls can reduce wear during contact.

[0016] In this invention, the stabilizing balls are engaged in a ring-shaped array of spherical grooves on the retaining ring, which limits the movement trajectory of the stabilizing balls and ensures that the stabilizing balls move along the rotation direction of the bridge gear. At the same time, it can also prevent the bridge gear from wobbling left and right during rotation, thereby improving the reliability of the bridge gear shaft assembly.

[0017] This invention uses the threaded engagement between the fixing bolt and the threaded fixing hole at the end of the support shaft to install the limiting stop plate onto the end of the support shaft, thereby mounting the bridge gear and the rolling stabilizer on the support shaft without affecting the normal rotation of the bridge gear on the support shaft.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-7 This utility model embodiment provides a highly reliable bridge gear shaft assembly, including an auxiliary bracket 1, a V-shaped frame 2 welded to the side of the auxiliary bracket 1, and a fixed shaft rod 6 fixedly connected in a rectangular array at the end of the V-shaped frame 2 away from the auxiliary bracket 1.

[0029] The fixed shaft 6 includes a support shaft 61 fixedly connected to the V-shaped frame 2. The support shaft 61 is equipped with a bridge gear 3 and a rolling stabilizer 5, and an end stop 4 is fixedly connected to the end of the support shaft 61 away from the V-shaped frame 2.

[0030] Furthermore, the rolling stabilizer 5 includes retaining rings 51 located on both sides of the bridge gear 3. The retaining rings 51 are provided with spherical slots 52 in a circular array, and each of the spherical slots 52 is engaged with a stabilizing ball 53.

[0031] By adopting the above technical solution, when the bridge gear 3 rotates on the support shaft 61, the stabilizing balls 53 on both sides of the bridge gear 3 will roll along with the bridge gear 3. The stabilizing balls 53 on both sides ensure the stability of the bridge gear 3 during rotation, prevent the bridge gear 3 from axial movement, and the rolling stabilizing balls 53 can reduce wear during contact.

[0032] Furthermore, the end stop 4 includes a limiting stop 41 that fits against the end of the support shaft 61, and the limiting stop 41 has a limiting groove 43 on the side near the support shaft 61, and a fixing bolt 42 is inserted through the limiting stop 41.

[0033] More specifically, the end of the support shaft 61 is provided with a threaded fixing hole 62, and the fixing bolt 42 passes through the support shaft 61 and is threadedly engaged with the threaded fixing hole 62.

[0034] By adopting the above technical solution, the stabilizing ball 53 is engaged in the annular array of spherical grooves 52 on the retaining ring 51, which limits the movement trajectory of the stabilizing ball 53, ensuring that the stabilizing ball 53 moves along the rotation direction of the bridge gear 3, and at the same time prevents the bridge gear 3 from wobbling left and right in rotation, thereby improving the reliability of the bridge gear shaft assembly.

[0035] Furthermore, the end of the support shaft 61 is provided with symmetrical limiting slots 63, and the side of the limiting plate 41 is integrally provided with a positioning block 44 corresponding to the limiting slot 63, and the positioning block 44 is inserted into the limiting slot 63.

[0036] Furthermore, the stabilizing ball 53 is respectively attached to the V-shaped frame 2 and the bridge gear 3, as well as the two sides of the bridge gear 3 and the limiting plate 41, and the bridge gear 3 and the support shaft 61 are interference-fitted with a movable bearing.

[0037] By adopting the above technical solution, the limiting plate 41 is installed on the end of the support shaft 61 through the threaded engagement between the fixing bolt 42 and the threaded fixing hole 62 at the end of the support shaft 61, thereby installing the bridge gear 3 and the rolling stabilizer 5 on the support shaft 61 without affecting the normal rotation of the bridge gear 3 on the support shaft 61.

[0038] Furthermore, the two adjacent bridge gears 3 are mutually driven and engaged, and power is transmitted through the meshing between the bridge gears 3.

[0039] Furthermore, the limiting plate 41 has a limiting groove 43 on the side near the support shaft 61, and the end of the support shaft 61 is located inside the limiting groove 43, ensuring that the side of the limiting plate 41 is in contact with the stabilizing ball 53.

[0040] The working principle of this utility model is as follows: In use, firstly, the V-shaped frame 2 is installed in the designated position using the auxiliary bracket 1. Then, one of the rolling stabilizers 5 is fitted onto the outside of the support shaft 61. Next, the bridge gear 3 is installed onto the outside of the support shaft 61. Then, the other rolling stabilizer 5 is fitted onto the end of the support shaft 61. Finally, the limiting plate 41 is placed on the end of the support shaft 61, and the positioning block 44 on the side of the limiting plate 41 engages with the limiting groove 63 at the end of the support shaft 61. Then, the end of the fixing bolt 42 passes through the limiting plate 41 and is threaded into the threaded fixing hole 62. When the bridge gear 3 rotates on the outside of the support shaft 61, the stabilizing ball 53 will follow the bridge gear 3 and roll in the spherical groove 52 on the retaining ring 51, ensuring the stability of the bridge gear 3 during rotation and preventing the bridge gear 3 from wobbling left and right during rotation. The structure is simple, the operation is very convenient, and it effectively reduces the intensity of manual labor.
