The non-lifting multi-tooth precision indexing table has good sealing performance, dust is not easy to enter between the upper and lower toothed discs, and the high indexing accuracy is affected. The load on the worktable is received by the thrust bearing with a large diameter, so the table faces the base. The parallelism of the bottom surface is not affected by the fitting of the toothed disc. It can be seen from the above that the advantage of the non-lifting multi-tooth precision indexing table is that high indexing precision and parallelism can be maintained during use, thereby ensuring the pin tooth housing. The accuracy and parallelism of the upper pin hole and the weight of the screw and the upper toothed disc are overcome by manual operation. Therefore, the selection of the multi-tooth indexing table for the multi-tooth indexing table in the processing of the labor-saving cycloidal speed reducer is selected. In the past, most of the multi-tooth precision indexing tables produced in China were uplifted. The multi-tooth fine-grading table used by the cycloidal speed reducer was lifted up. After using for a period of time, it lost high indexing accuracy due to the entry of dust. .
The selection of the number of teeth of the multi-tooth precision indexing table is usually the case of a tooth difference cycloidal pin gear case, the gear ratio of the pinion reducer, the number of the corresponding pin wheel, etc. The number of teeth of the multi-tooth precision indexing table should be As many integers as the number of teeth of the needle wheel, as far as possible, a multi-tooth precision indexing table can process the pin holes on the pin gear shells of various speed ratios, so as to reduce the number of the multi-tooth precision indexing table, so it is recommended. The following three multi-tooth precision indexing tables are used, the number of teeth of which are respectively teeth, wherein the multi-tooth precision indexing table of the teeth can process the transmission ratio, and the multi-tooth precision indexing table of the gear teeth can process the transmission ratio. Needle shell.
The multi-tooth precision indexing table of the tooth can process the gear ratio of the gear case. The general cycloid reducer is a complete torsion cycloid reducer. The difference in the number of teeth can only be one. When the transmission is relatively small, the tooth surface is easy to produce gluing. At present, the two-tooth differential cycloidal speed reducer is used to solve the problem of the tooth surface gluing when the transmission is relatively small. For example, the number of teeth of the two-tooth difference cycloidal wheel is odd. In the case of grinding the teeth with a cycloidal gear grinding machine, the grinding can be performed at one time, which not only improves the productivity, but also improves the grinding precision, and the number of teeth of the needle wheel is also an odd gear ratio. It can be seen from the above analysis that in order to ensure the accuracy of the pin hole of the needle thread housing of the processed cycloid, it is preferable to use the non-lifting multi-tooth precision indexing table in order to reduce the number of teeth of the multi-tooth precision indexing table.
