[0025] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Apparently, the described embodiments are some but not all of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the scope of protection of the present utility model.

[0026] Figure 1 Schematically shows an assembly structure of a roller stepless speed change disc applicable to the embodiments of the present utility model.

[0027] Refer to Figure 1-2 As shown, the present application provides an assembly structure of a roller stepless speed change disc, including:

[0028] An installation component for installing a fixed disc component and a moving disc component;

[0029] A fixed disc component for jointly adjusting the transmission speed ratio with the moving disc component; the fixed disc component is arranged on the installation component;

[0030] A moving disc component for jointly adjusting the transmission speed ratio with the fixed disc component; the moving disc component is movably arranged on the installation component and is opposite to the fixed disc component.

[0031] In the embodiments of the present application, the assembly structure of the roller stepless speed change disc provided by the present application is applied to a whole machine. By adjusting the magnitude of the power input of the stepless speed change drive pulley assembly, the moving disc component slides left and right on the installation component, so that the gap between the moving disc component and the fixed disc component becomes larger or smaller, realizing the adjustment of the transmission speed ratio.

[0032] Exemplarily, the installation component includes: a fixed disc fixing disc 2, the fixed disc component is arranged at the first end of the fixed disc fixing disc 2, and the moving disc component is arranged at the second end of the fixed disc fixing disc 2.

[0033] In the embodiments of the present application, the fixed disc fixing disc 2 is in spline connection with the input shaft 14.

[0034] Exemplarily, the installation component further includes: a left bushing 1 and a right bushing 12. Among them, the left bushing 1 is embedded in the open end of the first end of the fixed disc fixing disc 2, and the right bushing 12 is embedded in the open end of the second end of the fixed disc fixing disc 2.

[0035] In the embodiments of the present application, the spline of the fixed disc fixing disc 2 is in spline connection with the spline of the input shaft 14 of the whole machine, and is positioned and supported by the left bushing 1 and the right bushing 12. The spline of the fixed disc fixing disc 2 is in spline connection with the input shaft 14 of the whole machine, and the support of the left bushing 1 and the right bushing 12 is added, which improves the connection strength and reduces the failure rate.

[0036] In the embodiment of the present application, after the right bushing 12 is assembled with the input shaft 14, it is connected with a lock nut. The oil seal seat ring 13 is sealed with the oil seal 11 to form a closed housing space, preventing internal lubricating oil from leaking and external impurities from entering. The left bushing 1 and the right bushing 12 are added for auxiliary support, improving the connection strength and reducing the failure rate.

[0037] Exemplarily, the fixed disk assembly includes: a fixed disk 3, and the fixed disk 3 is disposed at the first end of the fixed disk 2 of the mounting assembly.

[0038] In the embodiment of the present application, the fixed disk 3 and the fixed disk 2 are connected by a positioning pin for positioning, ensuring the use accuracy of the product relative to the center line and reducing the failure rate.

[0039] Exemplarily, the moving disk assembly includes: a moving disk 4, and the moving disk 4 is disposed in the mounting assembly.

[0040] In the embodiment of the present application, when the moving disk 4 slides on the fixed disk 2 of the fixed disk, a rubber sealing ring 6 is used for the sealing lubricating grease, solving the oil leakage problem that occurs when the moving disk 4 slides left and right and reducing the failure rate.

[0041] Exemplarily, the moving disk assembly further includes: an oil nozzle 5, and the oil nozzle 5 is disposed on the moving disk 4.

[0042] In the embodiment of the present application, when the moving disk 4 slides on the shaft of the fixed disk 2 of the fixed disk, the change in the movement diameter of the driving wheel belt 16 is realized. Lubricating grease is injected into the oil storage tank of the moving disk 4 through the oil nozzle 5 for maintenance, ensuring that the moving disk 4 can be fully lubricated when sliding on the shaft of the fixed disk 2 of the fixed disk.

[0043] Exemplarily, the moving disk assembly further includes: a rubber sealing ring 6, and the rubber sealing ring 6 is disposed between the fixed disk 2 of the fixed disk and the moving disk 4.

[0044] In the embodiment of the present application, two rubber sealing rings 6 are installed at both ends of the inner hole of the moving disk 4 for the sealing of the sliding lubrication of the moving disk 4 on the fixed disk 2 of the fixed disk, preventing the excessive clearance caused by the friction and wear between the moving disk 4 and the fixed disk 2 of the fixed disk, and further the vibration, abnormal noise and noise that occur. At the same time, the rubber sealing ring 6 adopts a low-temperature resistant material to ensure that the use performance is not affected at minus fifty degrees.

[0045] Exemplarily, the moving disk assembly further includes: a moving disk cam 7 and a shield 8. Among them, the moving disk cam 7 is disposed on the moving disk 4, and the shield 8 is disposed on the moving disk cam 7, forming an installation space therebetween.

[0046] In the embodiment of the present application, the moving disk cam 7 and the moving disk 4 are connected by a spigot for positioning, and the shield 8 plays a role in protecting the internal parts.

[0047] Exemplarily, the moving disk assembly further includes: a fixed disk cam 9 and a spring 10, wherein both the fixed disk cam 9 and the spring 10 are disposed in the installation space and at the second end of the fixed disk 2.

[0048] In the embodiment of the present application, the fixed disk cam 9 is connected to the fixed disk 2, and after assembly, the vertical dimension consistency relative to the center line is good, ensuring the contact area between the convex spiral surfaces of the fixed disk cam 7 and the moving disk cam 9 when the driving wheel belt 16 is overloaded, and preventing the contact surface wear caused by the small contact area of the cam boss. The fixed disk cam 9 and the moving disk cam 7 ensure that the fixed disk 3 and the moving disk 4 rotate simultaneously during overload, preventing the belt from slipping and reducing the belt failure rate of the whole machine.

[0049] Exemplarily, the moving disk assembly further includes: an oil seal 11, and the oil seal 11 is disposed on the outer side wall of the shield 8.

[0050] In the embodiment of the present application, the oil seal 11 is connected to the integral engine oil seal seat ring 13 to form a sealed housing space, preventing internal lubricating oil leakage and external impurities from entering. The oil seal 11 is a fluororubber oil seal, improving the sealing performance at the input shaft 14, being able to remain intact in the Northeast region with a temperature of minus fifty degrees, and reducing the failure rate of oil leakage of the part oil seal.

[0051] In the embodiment of the present application, the mating length between the moving disk 4 and the fixed disk 2 is relatively long. The selection of materials, hardness, and clearance fit for both ensures that the clearance remains unchanged after the sliding friction of the moving disk 4 on the fixed disk 2, ensuring the durability of the assembly and use of the new type of roller stepless variable speed disk and reducing market failures.

[0052] In the embodiment of the present application, the distance between the fixed disk 3 and the moving disk 4 is determined by the magnitude of the force given to the inclined surface by the driving wheel belt 16, and the distance between the driving wheel belt 16 and the moving disk 4 and the fixed disk 3 is adjusted by the spring force, which determines the transmission diameter of the roller stepless variable speed disk assembly.

[0053] In the embodiment of the present application, the moving disk 4 moves left and right on the fixed disk 2, with a small clearance fit, similar material hardness, and a relatively long mating length, which increases the connection mating distance, effectively preventing the clearance between the moving disk 4 and the fixed disk 2 from increasing due to the left and right wear of the moving disk 4 caused by the radial force, improving the connection strength and reducing the failure rate.

[0054] In the embodiment of the present application, the moving disk 4 drives the rotation and power transmission of the entire new type of roller stepless variable speed disk assembly through the friction between the external driving wheel belt 16 and the inclined surface. Through the contact between the spiral surfaces of the moving disk cam 7 and the fixed disk cam 9 installed on the fixed disk 2, it effectively prevents only the fixed disk 3 or the moving disk 4 from rotating during overload.

[0055] In the embodiment of the present application, the moving disk cam 7 and the fixed disk cam 9 are provided with three anti-overload bosses to prevent the driving wheel belt 16 from driving the moving disk 4 or the fixed disk 3 to rotate during overload. Quenching treatment is carried out on the surfaces of the three overload cams of the moving disk cam 7 and the fixed disk cam 9 to increase the hardness. At the same time, lithium-based grease is used for lubrication in the cavity, which solves the problem of insufficient lubrication when the moving disk cam 7 and the fixed disk cam 9 are in force contact, and reduces the failure rate.

[0056] In the embodiment of the present application, the movement of the driving wheel belt 16 is realized by the sliding of the moving disk 4 on the shaft of the fixed disk 2. However, the main faults of similar products in the market are jamming caused by the small gap between the moving disk 4 and the fixed disk 3 or vibration and abnormal noise caused by the large gap.

[0057] In the embodiment of the present application, by selecting the fitting clearance between the fixed disk 2 and the moving disk 4, using materials and heat treatment, and filling lubricating oil through the oil nozzle 5, the lubrication requirements of moving parts are ensured, the wear resistance of the moving disk 4 on the fixed disk 2 is improved, and the failure rate of part vibration, abnormal noise and jamming is reduced.

[0058] In the embodiment of the present application, the fixed disk 3 is positioned by positioning pins and then installed on the fixed disk 2 with bolts, which ensures the coaxiality of the parts.

[0059] An assembly structure of a roller stepless speed change disk provided by the present application realizes high design precision, good strength, greatly improved sealing performance and service temperature of the new roller stepless speed change disk assembly structure through a new layout and structure design, reduces the market failure rate, greatly reduces the use cost and maintenance cost, and improves the competitiveness of the product.
