DEVICE FOR PRESS-FITTING GEAR SHAFT OF PLANETARY GEAR Technical Field of the Invention The present invention relates to a device for press-fitting a gear shaft of a planetary gear.
Background of the Invention A planetary gear is mounted on a planetary carrier by a gear shaft. To ensure the precise engagement and stable operation of planetary gears the fixation of the gear shaft is realized by interference fitting. First, an assembly operator needs to position and fix a planetary carrier assembly and then press-fit a gear shaft. Insufficient pressing or excessive pressing of the gear shaft often happens. As a result, when in use, the planetary gear will become loosen or will be separated from the planetary carrier assembly. It is unable to ensure the assembly quality. Moreover, before the press-fitting of the gear shaft, it is necessary to position the planetary carrier assembly and the planetary gear so as to realize the alignment of the gear shaft. However, since the planetary carrier assembly cannot be directly placed on a working platform, it is very difficult to position and fix the planetary gear and the assembly efficiency is low.
Summary of the Invention An objective of the present invention is to provide a device for press-fitting a gear shaft of a planetary gear, which can improve the assembly efficiency and the assembly quality.
For this purpose, the present invention employs the following technical solutions. A device for press-fitting a gear shaft of a planetary gear is provided, including a pedestal, a rear cover positioning member located on an upper side of the pedestal, and a press-fitting block located on an upper side of the rear cover positioning member, wherein a planetary carrier assembly is 1provided between the pedestal and the rear cover positioning member; the planetary carrier assembly includes a planetary carrier and a rear cover, and a planetary gear is provided between the planetary carrier and the rear cover; gear shaft holes used for fitting a gear shaft therein are formed on all the planetary carrier, the planetary gear and the rear cover; several vertical positioning pins are fixed within the pedestal; upper ends of the positioning pins extend outside the pedestal, and the positioning pins are moved up and down relative to the pedestal when stressed; several press-fitting pins extending downward are formed on the press-fitting block, and several first positioning holes running through the rear cover positioning member in an up-down direction are formed on the rear cover positioning member; the first positioning holes are in one-to-one correspondence to the gear shaft holes of the rear cover, and the press-fitting pins are in one-to-one correspondence to the positioning pins; and, the gear shaft holes of the planetary carrier and the gear shaft holes of the planetary gear can allow upper ends of the press-fitting pins to pass therethrough, and the first positioning holes and the gear shaft holes of the rear cover can allow lower ends of the press-fitting pins to pass therethrough.
When in use of the device of the present invention, the planetary carrier assembly is placed on the pedestal, and the upper ends of the positioning pins are located within the planetary gear; the rear cover positioning member is arranged on the upper side of the planetary carrier assembly so that the planetary carrier assembly is limited between the pedestal and the rear cover positioning member; then, the gear shaft to be press-fitted is arranged within a first positioning hole of the rear cover positioning member, and the lower end of the gear shaft is located within the gear shaft hole on the rear cover of the planetary carrier assembly to realize the alignment of the gear shaft; then, the press-fitting block is arranged on the upper side of the rear cover positioning member, and the lower ends of the press-fitting pins are located within the first positioning holes, and now, the upper ends of the positioning pins are resisted 2against the lower end of the gear shaft and the lower ends of the press-fitting pins are resisted against the upper end of the gear shaft, so that the assembly of the planetary carrier assembly with the device of the present invention is completed; and finally, a force is applied to the press-fitting block by a hand, so as to press in the gear shaft through the press-fitting pins. In the present invention, it is more efficient and convenient than the case where the gear shaft is pressed directly.
The positioning of the planetary gear and the planetary carrier assembly is realized by placing the lower end of the gear shaft or a lower end of a pin thinner than the gear shaft within the planetary gear. The assembly operator can also position the upper ends of the positioning pins within the planetary gear by moving the planetary gear. After the planetary carrier assembly is placed on the pedestal, that is, after the upper ends of the positioning pins are located within the planetary gear, the gear shaft or the pin is removed and then the rear cover positioning member is placed, or the rear cover positioning member is directly placed without removing the gear shaft. During the press-fitting of the gear shaft, the lower end face of the press-fitting block is resisted against the upper end face of the planetary carrier of the planetary carrier assembly, and the press-fitting block applies a force to the rear cover positioning member of the planetary carrier assembly to ensure the axial fixation of the planetary carrier assembly. The length of the positioning pins and the press-fitting pins is set as required in order to ensure the precise position of the press-fitted gear shaft, so as to improve the assembly quality and reduce the defective rate. The number of the positioning pins and the press-fitting pins is set as required in order to realize the press-fitting of all gear shafts at one time or the press-fitting of only one gear shaft at one time.
Preferably, a connector extending downward is formed on the planetary carrier, and a connector positioning hole fitted with the connector is formed on the pedestal. This arrangement is used for positioning the planetary carrier assembly. By forming a hole on the pedestal to fit the connector of the 3planetary carrier, it is easier and more convenient for positioning of the planetary carrier assembly in the present invention.
Preferably, the rear cover positioning member includes a positioning sleeve and a positioning mandrel fixed within the positioning sleeve; the first positioning holes are formed on the positioning sleeve, and the positioning mandrel is of a step structure with the outer diameter of a lower portion thereof being less than the outer diameter of an upper portion thereof; a bearing chamber is formed on an upper end face of the rear cover; a shaft hole for allowing a shaft to pass therethrough is formed on the rear cover, and the shaft hole is located within the bearing chamber; the rear cover positioning member cooperates with the planetary carrier assembly to position a lower portion of the positioning mandrel within the shaft hole; and, an outer wall of the lower portion of the positioning mandrel is resisted against an inner wall of the bearing chamber. The positioning mandrel is used for being positioned and fixed to the rear cover of the planetary carrier assembly, the positioning sleeve is used for guiding the press-fitting pins, and the positioning sleeve and the positioning mandrel are arranged fixedly. By clamping the positioning mandrel within the bearing chamber of the rear cover, the fixation of the rear cover positioning member and the planetary carrier assembly is realized. The height of the lower portion of the positioning mandrel can be selected as required in order to conveniently remove the positioning mandrel. The height of the lower portion of the positioning mandrel may be greater than the height of the bearing chamber.
Preferably, the pedestal includes a positioning pedestal on an upper side and a fixation pedestal on a lower side; a limiting lug protruded outward in a radial direction is formed in a lower portion of each positioning pin, and an upper through hole for allowing a portion of the positioning pin located on an upper side of the limiting lug to pass therethrough is formed on the positioning pedestal; the upper through hole runs through the positioning pedestal in an up-down direction; a lower through hole for allowing the limiting lug to pass 4therethrough is formed on the fixation pedestal; and, a compression spring is fixed on an lower side of the limiting lug of the positioning pin. In the present invention, the up-and-down movement of the positioning pin is realized by the compression spring. The limiting lug is used for limiting and fixing the lower portion of the positioning pin to prevent the whole positioning pin from detaching from the pedestal.
Preferably, there is one positioning pin and one press-fitting pin. Since the tooling of the present invention consists of a plurality of parts, it is very difficult to ensure the concentricity of the first positioning hole, the gear shaft hole of the planetary carrier assembly and the hole within which the positioning pin is located. Therefore, there is one positioning pin and one press-fitting pin, that is, one gear shaft is press-fitted at one time. Accordingly, the concentricity of parts above or under the gear shaft hole will not be taken into consideration, and the press-fitting efficiency becomes higher.
Preferably, a positioning guide column extending downward is formed on the press-fitting block; a second fitting hole fitted with the positioning guide column is formed on the positioning mandrel of the rear cover positioning member; and, the press-fitting block cooperates with the rear cover positioning member to position the positioning guide column within the second fitting hole.
This arrangement is used for positioning and fixing the press-fitting block and is convenient for press-fitting in the present invention. The second fitting hole can be allowed to run through the positioning mandrel in an up-down direction if desired, so that the lower end of the positioning guide column passes through the positioning mandrel and is then fitted within the shaft hole of the planetary carrier assembly.
Preferably, the positioning sleeve and the positioning mandrel are arranged separately; a radial section of the positioning sleeve is annularly arranged to contain a through groove for accommodating the positioning mandrel, several fixation holes extending inward in a radial direction are formed on an outer wall of the positioning sleeve, and the fixation holes are 5communicated with the through groove; internal threads are formed inside the fixation holes; and, screws are in threaded fit within the fixation holes, and the screws are resisted against the outer wall of the positioning mandrel. This arrangement is used for fixing the positioning sleeve and the positioning mandrel.

The end face positioning groove is used for radially limiting the planetary carrier of the planetary carrier assembly. Since the connector positioning hole runs through the pedestal in an up-down direction, it is convenient for machining the inner wall of the connector positioning hole, and it is convenient for fitting the connector in the connector positioning hole.
Preferably, the positioning pedestal is fixed to the fixation pedestal via a fastener; the lower through hole runs through the fixation pedestal in an up-down direction; a threaded structure is formed in a lower portion of the lower through hole, and a threaded block is in threaded fit within the lower portion of the lower through hole; a guide bump extending downward is formed on a lower end face of the limiting lug of the positioning pin; an upper end of the compression spring is sheathed outside the guide bump; and, the upper end of the compression spring is resisted against the limiting lug, while the lower end thereof is resisted against the threaded block.

The guide bump is used for axially positioning the compression spring to avoid the offset of the compression spring.
Preferably, a press-fitting plate is provided under the press-fitting block; a guide column through hole for allowing the positioning guide column to pass therethrough and a press-fitting pin through hole for allowing the press-fitting pin to pass therethrough are formed on the press-fitting plate; and, the diameter of the press-fitting plate is greater than the diameter of the positioning sleeve. The arrangement of the press-fitting plate is convenient for the fixation of the press-fitting block to the press-fitting pin and the positioning guide pin.
After the press-fitting pin and the positioning guide column pass through the press-fitting plate, the press-fitting block is fixed to the press-fitting pin and the positioning guide column. The thickness of the press-fitting plate can be selected as required to ensure the precise press-fitting position of the gear shaft. The diameter of the press-fitting plate is set as required to conveniently remove the press-fitting plate from the rear cover positioning member.
