Description

Technical Field

[0001] This utility model belongs to the field of mechanical equipment, specifically relating to an auxiliary device suitable for heavy-duty hard rail transmission, applied to hard rail transmission. Background Technology

[0002] Current large horizontal boring and milling machining centers generally use hardened rail transmission. However, relying solely on sliding friction through the plastic-coated surface results in a high coefficient of friction, high resistance, and a tendency to generate heat, leading to high maintenance requirements. The auxiliary device of this invention can change this situation by replacing single sliding friction with a combination of rolling and sliding friction, reducing heat generation, lowering the coefficient of friction, making the movement smoother, and simultaneously ensuring load-bearing capacity. Utility Model Content

[0003] Purpose of the utility model: In order to overcome the shortcomings of the prior art, this utility model provides an auxiliary device suitable for heavy-duty hard rail transmission, which can effectively improve the frictional resistance during heavy-duty hard rail transmission, reduce heat generation, and solve the crawling phenomenon during low-speed movement of hard rail transmission.

[0004] Technical solution: An auxiliary device suitable for heavy-duty hard rail transmission, comprising: a bottom rolling element and side rolling elements, wherein the bottom rolling element is fixedly installed on the plastic-coated surface, and the side rolling elements are fixedly installed on two sides of the contact surface of the hard rail;

[0005] The bottom rolling element is fixedly mounted on the rolling element mounting plate, and the bottom of the rolling element mounting plate is provided with a mounting plate gasket.

[0006] The side rolling element is fixedly installed on the rolling element side brake iron, and the rolling element side brake iron is fixedly installed on the brake iron base.

[0007] As an optimization: the mounting plate shims are used to adjust the height, ensuring that the installation height of the bottom rolling element is slightly higher than the height of the plastic-coated surface, and ensuring that the bottom rolling element and the plastic-coated surface are in contact with the hard rail at the same time, so as to achieve a combination of rolling friction and sliding friction.

[0008] As an optimization: the side rolling element is adjusted by a 1:50 slope between the brake base and the side brake of the rolling element, so that the side rolling element has good contact with the hard rail and the two sides of the contact surface of the hard rail, thereby achieving rolling friction.

[0009] As an optimization: a suitable position is taken on the bottom surface of the plastic-coated surface to sink it, leaving space for the installation of the mounting plate gasket, the rolling element mounting plate and the bottom rolling element.

[0010] As an optimization: the two ends of the two sides of the hard rail contact surface are appropriately positioned to mill out the installation space for the rolling element side brake and the brake base.

[0011] Beneficial effects: The auxiliary device of this utility model is a hard rail auxiliary transmission structure that combines rolling elements and plastic-coated surfaces. It can improve the straightness accuracy during high-speed operation, effectively reduce the heat generation of the plastic-coated surfaces, reduce the maintenance requirements of traditional hard rails, improve the service life of the plastic-coated surfaces of hard rails, and solve the problem of creeping phenomenon during low-speed operation.

[0015] Example

[0016] like Figure 1-3 As shown, an auxiliary device suitable for heavy-duty hard rail transmission includes: a bottom rolling element 1 and a side rolling element 6. The bottom rolling element 1 is fixedly installed on the plastic-coated surface 7, and the side rolling elements 6 are fixedly installed on the two sides of the hard rail contact surface 8.

[0017] A suitable position is selected on the bottom surface of the plastic-coated surface 7 to allow space for the mounting plate shim 3, the rolling element mounting plate 2, and the bottom rolling element 1. The bottom rolling element 1 is fixedly mounted on the rolling element mounting plate 2. The bottom of the rolling element mounting plate 2 is provided with a mounting plate shim 3, which is used to adjust the height to ensure that the installation height of the bottom rolling element 1 is slightly higher than the height of the plastic-coated surface 7. This ensures that the bottom rolling element 1 and the plastic-coated surface 7 are in contact with the rigid rail simultaneously after bearing load, so as to achieve a combination of rolling friction and sliding friction.

[0018] At appropriate positions at both ends of the two sides of the hard rail contact surface 8, the installation space for the rolling element side brake 4 and the brake base 5 is milled out. The side rolling element 6 is adjusted by the 1:50 slope of the brake base 5 and the rolling element side brake 4 to ensure good contact between the side rolling element 6 and the hard rail and the two sides of the hard rail contact surface 8, realizing rolling friction. This improves the friction coefficient of traditional surface-to-surface sliding friction, reduces heat generation, and makes the movement smoother and more stable.

[0019] The auxiliary device of this utility model is a hard rail auxiliary transmission structure that combines rolling elements and plastic-coated surfaces. It can improve the straightness accuracy during high-speed operation, effectively reduce the heat generation of the plastic-coated surfaces, reduce the maintenance requirements of traditional hard rails, increase the service life of the plastic-coated surfaces of hard rails, and solve the problem of creeping phenomenon during low-speed operation.
