Problems solved by technology

The existence of tooth shape error destroys the normal meshing of the gear pair, making the meshing point deviate from the meshing line, which causes the transformation of the instantaneous transmission ratio, resulting in the instability of the gear transmission
The existence of tooth direction error destroys the uniformity of the total load distribution of the gear in the transmission process, making it concentrated in a certain place, shortening the service life of the gear

Embodiment Construction

[0009] The technical solution will be described in detail below through a best embodiment, but the protection scope of the present invention is not limited to the embodiment.

[0010] like figure 1 As shown, a gear measuring device includes a workbench 1, a base 3 arranged on the top of the workbench 1, the base 3 is provided with 4 grooves, the groove is provided with a bracket 4, and the bracket 4 It is fixedly connected with the groove by a hexagonal bolt 8 and a hexagonal nut 10. The gear 6 to be tested is placed on the short beam of the bracket 4, and a leveling screw 7 is arranged between the gear 6 and the short beam of the bracket 4. The gear 6 to be tested and the bracket 4 are tightly fixed by the tightening screw 5 .

[0011] The workbench 1 and the base 3 are connected by four combined compression screws 2 . The base 3 is a hollow casting with 4 ribs inside. Copper sleeves are welded at the ends of the four combined compression screws 2 .

Abstract

The invention discloses a gear measuring device. The gear measuring device comprises a working table and a base which is arranged on the top of the working table, wherein the base is a hollow casting; four rib plates are arranged in the base; the working table is connected with the base through four combined forcing screws; four grooves are formed in the base; a support is arranged on the grooves and is fixedly connected with the grooves through hexagon bolts and hexagon nuts; a gear to be measured is arranged on a short beam of the support; and leveling bolts are arranged between the gear and the short beam of the support. The weight of the gear measuring device is reduced by the adoption of the hollow base; the four rib plates are arranged in the middle of the gear measuring device, so that the loading capacity of the gear measuring device is improved; the gear measuring device can adapt to disc-shaped gears of different specifications by adjusting the clamping position of the base, so that the gear measuring device is high in universality; four puller bolts are arranged in the device, so that the gear can be aligned quickly by turning finely; and a copper bush is welded on the top of each of the combined forcing screws, so that the working table and surfaces of parts are prevented from being damaged.

Description

technical field [0001] The invention relates to a gear fixing and measuring device, in particular to a disk-shaped gear fixing and measuring device. Background technique [0002] As a basic component for power and motion transmission, gears have the characteristics of large power range, high transmission efficiency, long service life, safety and reliability, and have become an indispensable transmission part for many mechanical products. The design and manufacturing level of gears will directly affect the performance and quality of mechanical products, and the detection of gear tooth shape and tooth direction is also essential. The existence of tooth shape error destroys the normal meshing of the gear pair, and makes the meshing point deviate from the meshing line, which causes the transformation of the instantaneous transmission ratio and leads to the instability of the gear transmission. The existence of tooth-tooth error destroys the uniformity of the total load distribu...
