Problems solved by technology
The nylon spline sleeve is connected with the transmission shaft B and the pulley C through splines. Not only is the structure relatively complex, the processing cost is high, and maintenance and replacement are difficult. More importantly, the thermal stability and self-lubricating properties of nylon are softer than those of PTFE. Belt difference, long-term rise in working temperature will cause the sliding mechanism to be stuck

Embodiment Construction
[0018] A process of sticking plastic on the surface of the hole, such as image 3 As shown, the specific steps are as follows:
[0019] Semi-finish the holes on the workpiece 1 that need to be pasted with plastic to the size specified by the process, and the roughness of the holes is controlled between Ra12.5~Ra25;
[0020] Clean the surface of the hole with a cleaning agent such as acetone to remove dust and oil;
[0021] ③ Place the workpiece in a dust-free working area with a temperature of 10-40°C and a relative humidity of 70%-75%;
[0022] ④Apply the adhesive evenly on the surface of the hole;
[0023] ⑤ Paste the soft tape 2 on the surface of the hole;
[0024] ⑥ Use special tooling to apply uniform expansion force to the soft belt and keep it solidified for more than 24 hours; the special tooling includes a circular sleeve 3 with an inner taper hole, and the middle section is a tapered The first section and the front section are the tapered mandrel 4 of the thr...

The invention provides a process for laminating the surface of a hole, comprising the following steps of: carrying out semi-finishing on the hole needing to be laminated of a work piece and washing the surface of the hole with a cleaning agent; controlling the temperature of a working area for laminating the surface of the hole in a range of 10-40 DEG C and controlling the relative humidity to be 70-75%; uniformly brushing a binding agent on the surface of the hole and then sticking a soft belt; and then, utilizing a special tool to apply a tension force to the soft belt and keeping curing for more than 24 hours, wherein the special tool comprises a circular sleeve with an inner taper hole, the middle section of the special tool is a tapered section capable of being assembled in the taper hole of the circular sleeve and the front section of the special tool is assembled with a tapered core shaft of a thread cylinder section of a clamping nut; arranging the circular sleeve in the hole of the work piece and inserting the tapered core shaft into the taper hole in the circular sleeve; assembling the clamping nut on the thread cylinder section at the front end of the tapered core shaft; applying the tension force to the soft belt through screwing the clamping nut until the binding agent is cured; taking off the special tool and then carrying out finish machining on the soft belt to a needed inner hole size. According to the process provided by the invention, a circular guide rail has the advantages of low speed, no creeping, convenience for replacement, and good self-lubricity.
Description
technical field [0001] The invention relates to the technical field of reducing friction and improving lubrication between two contact surfaces of sliding parts. Background technique [0002] Plane lamination is widely used in the machinery industry. The short guide rail surface of many machine tools is pasted with PTFE-based soft tape to reduce the friction coefficient and eliminate the low-speed crawling phenomenon of the machine tool. However, when pasting plastic on the curved surface of moving parts, such as pasting plastic on the hole surface of a cylindrical guide rail, it is more difficult to apply uniform expansion force to the curved surface during the pasting process than flat plastic pasting, so that the soft belt cannot be firmly attached to the metal curved surface. Make sticking plastic on hole surface always can't reach desirable technical effect, nobody uses so far. For this reason, many manufacturers have to adopt such as figure 1 In the structure shown, ...
