Description

Technical Field

[0001] This utility model relates to the field of press-fitting technology, and in particular to a gear press-fitting device. Background Technology

[0002] A shaft is a cylindrical object that passes through the center of a bearing, wheel, or gear, although some are square. A shaft is a mechanical part that supports rotating parts and rotates with them to transmit motion, torque, or bending moment. It is generally a round metal rod, and different sections can have different diameters. Rotating parts in a machine are mounted on shafts.

[0003] Gears are typically assembled onto shafts for use. When an interference fit is required between the gear and the shaft, press fitting is the most common assembly method. Existing press fitting equipment includes a support platform with a fixed height, a corresponding pressure plate on top of the support platform, and a hydraulic cylinder above the pressure plate. During operation, tooling such as sleeves is needed to support or act as force transmission components, acting on the shaft and gear respectively, causing them to move towards each other and assemble. Because the height of the support platform cannot be changed, the working range of this press fitting equipment is relatively limited, and it also requires the use of tooling. Utility Model Content

[0004] To address the aforementioned problems, this utility model discloses a gear pressing device, comprising a housing, a guide rail fixedly connected to the lower front of the housing, and a lifting platform slidably mounted on the guide rail. That is, the lifting platform changes its height with the aid of the guide rail.

[0005] A hydraulic cylinder is fixedly connected to the upper end of the housing. A telescopic rod extends from the lower end of the hydraulic cylinder, and a connecting member is fixedly connected to the lower end of the telescopic rod. Two clamping rods are provided on the connecting member, and a first slider is fixedly connected to the end of each clamping rod. The first slider slides onto the connecting member. When the hydraulic cylinder is activated, the telescopic rod extends, and the clamping member clamps onto the end face of the gear, achieving gear press-fitting. Furthermore, the two clamping rods ensure the gear's force balance, and the sliding clamping rods facilitate adjustment of the distance between them, making it suitable for assembling gears and shafts of different sizes.

[0006] Preferably, the connector includes a rod body, the lower part of which is provided with a groove, and a first slider is slidably engaged in the groove. The groove and the first slider facilitate changing the position of the clamping rod on the connector.

[0007] Preferably, a through hole is provided on one side of the rod, and a first bolt is inserted through the through hole and threadedly connected to the first slider. After the position of the clamping rod is changed, the first bolt is tightened to fix the position of the clamping rod.

[0008] Preferably, a connecting sleeve is fixedly connected to the upper end of the rod, and the connecting sleeve fits into the lower end of the telescopic rod. Ribs are fixedly connected to the upper end of the rod. The ribs are added to increase the structural strength of the connector and ensure stable operation of the equipment.

[0009] Preferably, the lifting platform includes a back plate, and a second slider is fixedly connected to the back of the back plate, and the second slider is slidably engaged with a guide rail. The second slider enables the lifting platform to slide on the guide rail.

[0010] Preferably, an upper plate is fixedly connected to the upper part of the back plate, the upper plate is provided with positioning holes, and a rib is fixedly connected to the lower part of the upper plate, with one side of the rib fixedly connected to the back plate. The rib also increases the structural strength of the lifting platform.

[0011] Preferably, the front of the back plate is threaded with a plurality of second bolts, the ends of which abut against the guide rail. By tightening the second bolts, in conjunction with the structure of the second slider, the lifting platform is fixed to the guide rail.

[0012] The beneficial effects of this utility model are as follows: 1. Equipped with a lifting platform, the lifting platform can adjust its height on the guide rail. Combined with the stroke of the hydraulic cylinder, it greatly improves the applicability of the equipment, that is, it can accommodate a larger length of shaft components.

[0013] 2. The lifting platform is equipped with positioning holes, and two clamping rods are provided on the connecting parts. The distance between the two clamping rods can be adjusted according to the diameter of the shaft and the size of the gear, ensuring stable force on the gear. At the same time, this setting can reduce or even eliminate the need for tooling to complete the pressing of the gear. Attached Figure Description
