Embodiment 1

[0032] A gear rack meshing test device, such as Figure 1-Figure 4 As shown, the basic test bench 3 is included, and the basic test bench 3 is provided with a rack seat 4 and two cylinders 5 with guide rods 51. The two cylinders 5 are symmetrically arranged, and the two cylinders 5 pass through the corresponding guide rods 51. Connected to both ends of the rack seat 4. The rack seat 4 is equipped with the tested rack 2, specifically, there is a notch 71 in the rack seat 4 for placing the tested rack 2; considering the size difference of different test objects and different test situations , Fasten the tested rack 2 by threaded connection at both ends of the notch 71 of the rack seat 4, which facilitates operations such as installation and disassembly. The basic test bench 3 is also provided with a gear 1 driven by a motor 10. The gear 1 only performs forward and reverse rotation at a fixed position, and provides driving force for the tested rack 2. The gear 1 and the tested r...

Embodiment 2

[0041] Based on Example 1, such as Figure 1-Figure 4 , The basic test bench 3 is provided with a drive system mounting plate 7 . The drive system mounting plate 7 is provided with a second drive mechanism mainly composed of a motor 10, a first coupling 11, and a gear box 13; the gear 1 is combined with the second drive mechanism through the second coupling 12, and passed through The gear carrier bearing 14 is connected with the drive system mounting plate 7 . Correspondingly, the drive system mounting plate 7 is provided with a notch 71 for the gear 1 to pass through, and the width of the notch 71 is consistent with the width of the chute 31, providing enough space for the engagement of the gear 1 and the tested rack 2, and Easy to locate and observe. The drive system mounting plate 7 is used to integrate and install the gear 1 and the second drive mechanism, so as to facilitate the adjustment of the position of the gear 1 to obtain the wear condition of the gear 1 meshing ...

Abstract

The invention relates to the field of rack rail traffic systems, and concretely relates to a rack rail meshing test device. The device comprises a basic test bench, a rack seat and a first driving mechanism are arranged on the basic test bench, the first driving mechanism is fixedly connected with the rack seat, the first driving mechanism is used for driving the rack seat to do reciprocating motion, and the rack seat is provided with a tested rack; and a gear driven by a motor is further arranged on the basic test bench, the gear is meshed with the rack to be tested, and the gear is used for driving the rack to be tested to do linear reciprocating motion. The rack rail meshing test device can simulate the actual operation condition of a rack rail railway, and according to the actual operation condition of the rack rail railway, a series of tests conforming to the actual operation condition of the rack rail railway are carried out on the abrasion condition of the rack in rack rail gear and rack meshing so as to obtain various parameter performance of the gear and the rack rail; and reliable test data is provided for formulating the gear and rack rail standard.

Description

technical field [0001] The invention relates to the technical field of rail transportation, in particular to a rack meshing test device. Background technique [0002] Cog railways are widely used in road development located in mountainous terrain. At present, many countries in Europe have built a number of cog rail-based rail transit and developed many high-quality tourism resources. However, there are no construction standards and engineering applications for cog rail-related rail transit in my country. [0003] The most critical thing in the rack traffic system is the meshing transmission system between the gear and the rack, which provides a large climbing power for the running train through the meshing transmission between the gear and the rack. In order to break through the key technology of the rack system in the rack system, relevant technical personnel have begun to conduct research on the key technologies of the rack system and its subsidiary mechanisms. Before de...
