Embodiment 1

[0056] like Figure 1 to Figure 7 As shown, a closed roller screw mechanism assembly method includes the following steps:

[0057] Step 1, tooling assembly, the auxiliary assembler 1 is installed on the vertical assembly platform 2, the end of the auxiliary assembler 1 is far away from the assembly platform 2, and a number of circumferential arrays are arranged around the axis of the auxiliary assembler 1 An assembly groove 11 arranged vertically, and a through assembly opening 21 is provided on the assembly platform 2 facing the position where the auxiliary assembler 1 is installed;

[0058] Step 2: Install the rollers, insert the rollers 31 one by one in the assembly groove 11 at any time, and screw the first rollers 31 corresponding to the rollers 31 on the end of the auxiliary assembler 1 close to the assembly platform 2. Fastener 12;

[0059] Step 3, pre-positioning the rollers, installing a ring-shaped assembly locator 4 on the end of the auxiliary assembler 1 away fro...

Embodiment 2

[0070] Figure 8 It is a schematic flow diagram of a method of Embodiment 2 of an assembly method of a closed roller screw mechanism of the present invention; Figure 8 As shown, the components that are the same as or corresponding to those in the first embodiment are marked with the corresponding reference numerals in the first embodiment. For the sake of simplicity, only the differences from the first embodiment will be described below. This embodiment two and figure 1 The difference of the shown embodiment one is:

[0071] like Figure 8 and Figure 9 As shown, it also includes step ten, sealing installation, respectively assembling sealing end caps 36 and retaining rings 37 at the openings of the axial ends of the nut 33, and the sealing end caps 36 connecting the rollers 31, teeth Ring 34, limiter 35 and the threaded part of the roller 31 and the screw 32 are sealed in the nut 33, and the retaining ring 37 is against the nut 33 and the sealing end cover 36 between. ...

Embodiment 3

[0075] Figure 10 It is a structural schematic diagram of Embodiment 3 of an assembly method of a closed roller screw mechanism of the present invention; Figure 10 As shown, the parts that are the same as or corresponding to those in the second embodiment are marked with the corresponding reference numerals in the second embodiment. For the sake of simplicity, only the differences from the second embodiment will be described below. This embodiment three and Figure 9 The differences of the illustrated embodiment two are:

[0076] like Figure 10 As shown, the inner ring of the sealing end cap 36 is provided with a threaded portion 361 that is mated with the external thread on the screw rod 32 .

[0077] It should be noted that, in order to improve the sealing performance of the sealing end cap 36, a threaded part 361 that is matched with the external thread of the screw rod 32 is provided on the inner ring of the sealing end cap 36, so that the sealing end cap 36 can be co...

Abstract

The invention relates to the technical field of roller lead screw mechanism assembling, and particularly discloses a closed roller lead screw mechanism assembling method. According to the method, by utilizing an assembling tool formed by combining an auxiliary assembler with an assembling platform, quick and accurate assembling of a screw, a roller and a nut is conducted; in the assembling process, cooperation between the roller and the screw can be quickly adjusted by rotating the screw, and the technical problems that assembling of the roller, the screw and the nut is low in speed and poor in precision are solved; and in addition, the two ends, in the axial direction, of the nut are provided with sealing end covers, the roller, a gear ring, a stopper and the portion, in threaded fit withthe screw, of the roller are sealed in the nut through the sealing end covers, sealing protection is advantageously conducted through the sealing end covers, meanwhile, a lubricating medium inside isstopped from flowing out, and the service life is prolonged.

Description

technical field [0001] The invention relates to the technical field of assembling a roller screw mechanism, in particular to an assembling method for a closed roller screw mechanism. Background technique [0002] A roller screw mechanism includes an externally threaded screw, a nut disposed around the screw and including internal threads, and a plurality of longitudinal rollers disposed between the screw and the nut and having a connection with the external threads of the screw and the nut. External threads engaged by internal threads. [0003] When assembling the roller screw mechanism, the external thread of the roller must match the external thread of the screw and the internal thread of the nut at the same time, and the number of rollers is large. Therefore, in the assembly process , It is difficult to quickly assemble the screw, nut and roller, and if the assembly is not in place, it will cause mutual wear between the screw, roller and nut, resulting in hidden dangers ...
