Detailed Description

Referring to fig. 1 and 2, the utility model discloses a transmission case 1, gear shaft 8, rolling bearing 4, chain 5, sprocket 6 and needle bearing 7 with a seat, parallel on the both sides wall of transmission case 1 is equipped with axle bed 11 and lower axle bed 12.

Referring to fig. 1 and 2, the seated ball bearings 4 are four pieces and are respectively disposed on the upper gear shaft seat 11 and the lower gear shaft seat 12 of the transmission case 1.

Referring to fig. 1 and 2, the gear shaft 8 is a shaft member having a gear 82 and a needle journal 83 at one end and a connector holder 84 at the other end, a sprocket holder 85 is disposed at the middle of the gear shaft 8, and ball bearing necks 81 are disposed at both sides of the sprocket holder 85.

Referring to fig. 1 and 2, the chain wheel 6 is disposed on a chain wheel seat 85 of the gear shaft 8, and the needle bearing 7 is disposed on a needle journal 83 of the gear shaft 8.

Referring to fig. 1 and 2, the gear shaft 8 is divided into two pieces, and the ball bearing necks 81 of the two gear shafts 8 are respectively hinged with the ball bearings 4 with seats of the upper and

lower axle seats

11 and 12; the chain 5 is meshed between the chain wheels 6 on the two gear shafts 8.

Examples

Referring to fig. 1, 2 and 3, the present invention is used on a vehicle carrying frame 2 of a lifting translation parking device, a main transmission shaft 22 is arranged at the bottom of the vehicle carrying frame, a motor reducer 21 is arranged on the vehicle carrying frame 2, the output end of the motor reducer 21 is connected with the main transmission shaft 22,

when in use, two pieces of the invention are symmetrically arranged, the transmission case body 1 of the invention is fixed at two sides of the vehicle-carrying frame 2, and the connector seat 84 of the gear shaft 8 of the lower axle seat 12 is connected with the main transmission shaft 22 of the vehicle-carrying frame;

referring to fig. 1, 2 and 3, finally, the gear 82 and the ball bearing journal 81 of the present invention are mounted in the L-shaped rack guide rail of the lifting translation parking apparatus together with the vehicle carrier; when the parking device works, the control cabinet controls the motor reducer, the motor reducer drives the main transmission shaft 22 and the gear shaft 8 and the gear 82 of the lower axle seat 12, the gear shaft 8 of the lower axle seat 12 drives the gear shaft 8 and the gear 82 of the upper axle seat 11 through the chain wheel 6 and the chain 5, the gear 82 is meshed with the rack in the L-shaped rack guide rail, and the needle roller shaft neck 83 rolls on the side wall of the L-shaped rack guide rail, so that the parking device and the vehicle carrier move in the L-shaped rack guide rail of the parking device, and the purpose of parking the vehicle in a parking device in a lifting and translation mode or moving the vehicle out of the parking device is achieved.
