Embodiment 1

[0024] Such as Figure 8 As shown, the circumferential positioning structure of the oil cylinder body in this embodiment includes the spacer circumferential positioning structure and the oil cylinder body, and the spacer circumferential positioning structure includes the box body 3 of the gearbox and the annular isolation box installed in the box body 3. Frame 1, cylindrical pin 2, oil cylinder body 5 and spacer 1 are coaxially installed in casing 3, and the right end of annular spacer 1 is adjacent to the left end of oil cylinder body 5. Wherein the oil cylinder block 5 is the oil cylinder block of the forward first gear clutch of the gearbox.

[0025] Such as Figure 7 As shown, the circumferential surface of the spacer 1 is provided with an axial positioning groove 11, the left end of the positioning groove 11 does not radially penetrate the spacer, and the right end of the positioning groove 11 extends to the end surface of the right end of the spacer 1.

Embodiment 2

[0031] Such as Figure 9 Figure 10 As shown, the circumferential positioning structure of the cylinder block of the forward first gear clutch in this example is different from the circumferential positioning structure of the cylinder block in Embodiment 1 in that only the cylindrical side of the cylindrical pin 2 Positioning plate slot 21 is set, such as Figure 9 shown. The right end of the positioning groove 12 on the spacer 1 is completely radially penetrated, and the left end of the positioning plate 4 is embedded in the positioning plate slot 21 on the cylindrical pin 2, so as to realize the radial support of the left end of the positioning plate 4 and prevent the positioning plate 4 from being placed in the oil cylinder. The cylinder body shakes radially during the movement, thereby improving its stability and reliability.

Abstract

Oil cylinder block circumferential positioning structure and planetary gearbox. The invention relates to a circumferential positioning structure of an oil cylinder body. In order to solve the problem of poor reliability of the circumferential positioning of the oil cylinder body of an existing planetary gearbox, a circumferential positioning structure of the oil cylinder body is provided, including a circumferential positioning structure of an isolation frame, an isolation frame The circumferential positioning structure includes a box body, an annular spacer, and a cylindrical pin. The oil cylinder body and the spacer are coaxially installed in the box body. The right end of the annular spacer is adjacent to the left end of the oil cylinder body. There is a positioning groove on the spacer. There are pin holes on the box body, and the two ends of the cylindrical pin are inserted into the pin holes and the left end of the positioning groove; the cylinder body is provided with a positioning plate installation groove, and the positioning plate installation groove is provided with a positioning plate whose left end extends into the positioning groove , the circumferential positioning structure of the spacer is provided with a radial positioning support mechanism for radial positioning and supporting the left end of the positioning plate. Both ends of the positioning plate used for the circumferential positioning of the oil cylinder block in the present invention have radial supports, so that it is stable and will not shake due to frequent movement of the oil cylinder block, and its reliability is improved.

Description

technical field [0001] The invention relates to a gearbox, more specifically, to a circumferential positioning structure of an oil cylinder in a forward first gear clutch of a planetary gearbox and a planetary gearbox. Background technique [0002] In the engineering machinery industry, the oil cylinder block circumferential positioning structure of the forward first-gear clutch of the existing BS305 planetary gearbox is composed of a box body 3, a straight pin 2, an isolation frame 1, a positioning plate 4, and an oil cylinder body 5, such as figure 1 As shown, the positioning principle is as follows: [0003] Such as figure 2 As shown, a positioning groove 11 is arranged on the cylindrical surface of the spacer 1, the left end of the positioning groove 11 is not penetrated radially, and the right end is radially penetrated, and the box body 3 is provided with a pin hole corresponding to the positioning groove 11, and the cylindrical pin 2 structured as image 3 As show...
