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

The invention relates to a circumferential positioning structure of an oil cylinder body and a planetary transmission. The circumferential positioning structure of the oil cylinder body aims to solvethe problem of the poor circumferential positioning reliability of the existing planetary gearbox oil cylinder body. The circumferential positioning structure of the oil cylinder body comprises an isolation frame circumferential positioning structure. The isolation frame circumferential positioning structure comprises a box body, an annular isolation frame and a cylindrical pin. The oil cylinder body and the isolation frame are coaxially installed in the box body. The right end of the annular isolation frame is adjacent to the left end of the oil cylinder body. The isolation frame is providedwith a positioning groove. The box body is provided with a pin hole. The two ends of the cylindrical pin are inserted into the pin hole and the left end of the positioning groove. The oil cylinder body is provided with a positioning plate mounting groove. A positioning plate with the left end extending into the positioning groove is arranged in the positioning plate mounting groove. The isolationframe circumferential positioning structure is internally provided with a radial positioning and supporting mechanism for radially positioning and supporting the left end of the positioning plate. According to the circumferential positioning structure, the two ends of the positioning plate for oil cylinder body circumferential positioning are supported radially, so that the positioning plate is stable, does not shake due to frequent movement of the oil cylinder body, and is better in reliability.

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...
