The paper deals with the planetary train and its creative application in the ZQ-1 automatic Lifting gear mechanism of the rolling door with fireproof; The description analyzes and explores the w-hole designing process with regard to the working principle, designing and computation, and strength test and check-up;
By means of fracture analysis,bending strength and contact strength check of fan reducer gear for cooling water tower, the reasons of gear tooth broken are found. The corresponding improvements are proposed.
The cause of gear breaking and impeller rubbing on casing of Roots blower was analysed based on stress state of gear and bear,and two measures were made to improve stress state of gear at high capacity 〔
The occurring mechanism and corresponding calculation formula of viscous elasticity delayed energy consumption of engineering plastics are introduced,and the viscous elasticity delayed energy consumption of plastics bearing and gear are calculated and analyzed,offering theory gist of the design and application of plastics bearing and gear
Results show that there can be four situations for meshing boundary line on the tooth surface of gear, namely, inexistence of meshing boundary line, a unique line, two lines, and two coincident lines.
Research on transmission principle and kinematics analysis for involute spherical gear
A new kind of transmission-type spherical gear called 'ring involute spherical gear mechanism' is introduced.
Compared to the famous TRALLFA spherical gear, this new spherical gear has an involute tooth profile, and a ring tooth that is distributed continuously on the surface of the sphere.
This allows the gear to overcome two disadvantages of the TRALLFA spherical gear: the drive principle error and the manufacturing difficulty.
