Abstract
The utility model relates to a gear transmission demonstration instrument. A driving spur gear and a driven spur gear are installed on an instrument rack, wherein the driving spur gear and a driven spur gear are engaged with each other; a driving helical gear is installed at an outermost end of a central shaft of the driven spur gear and is engaged with a helical gear; the helical gear drives a driven wheel by a chain; and a group of circular plates are coaxially installed on an output shaft of the driven wheel. Besides, ten gravity objects are uniformly installed on an input shaft of the driving spur gear and each two opposite gravity objects are connected by a lever passing through the center of the input shaft; and two gravity objects are uniformly installed on the central shaft of the driven spur gear and each two opposite gravity objects are connected by a lever passing through the center of the central shaft. According to the utility model, the provided gear transmission demonstration instrument has advantages of reasonable design and simple operation; the transmission processes of various gears can be displayed visually, so that the people can understand and grasp the gear structure and the transmission principle thereof.
Description
Technical field
The utility model belongs to teaching aid, especially a kind of gear drive demonstrator.
Background technology
Gear drive is the wherein the most frequently used kind of drive, and it provides power for machine.Gear drive generally includes the multiple kind of drive, and the kind of gear is more, and relatively more commonly used is spur gear and spiral gear.At present, school generally adopts written explanation when gear drive is explained, there is not intuitively apparatus for demonstrating, be unfavorable for like this understanding gear-driven process, be difficult for to grasp its motion principle, therefore develop a kind of multiple gear transmission mode comprehensively can being very important to together gear drive apparatus for demonstrating directly perceived.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of gear drive demonstrator is provided, this device design is reasonable, simple to operate, the transmission process of multiple gear can be displayed intuitively, is convenient to people to understanding, the grasp of gear structure and transmission principle thereof.
The utility model solves its technical matters and is achieved through the following technical solutions:
A kind of gear drive demonstrator, comprise instrument stand, it is characterized in that: at instrument stand intermeshing active spur gear and driven spur gear are installed, the outermost end of the central shaft of driven spur gear is installed an active oblique gear, this active oblique gear meshes a spiral gear, this spiral gear is by chain drive one engaged wheel, one group of disk of coaxial installation on the output shaft of this engaged wheel; Ten gravity things of uniform installation on the input shaft of described active spur gear, per two gravity things that are oppositely arranged connect by a lever that passes the input shaft axle center; Ten gravity things of uniform installation on the central shaft of described driven spur gear, per two gravity things that are oppositely arranged connect by a lever that passes the central shaft axle center.
Coaxial mounted disk is two on the output shaft of described engaged wheel, and the equal radial equipartition of each disk is installed ten power-assisted pins.
The pin rod of the power-assisted pin that described two disks are installed is oppositely arranged.
Advantage of the present utility model and beneficial effect are:
1, the utility model is demonstrated out intuitively with the gear drive process by the transmission that interconnects of spur gear, spiral gear and chain, is convenient to people and understands gear drive principle and transmission process.
2, the utility model is simple in structure, reasonable in design, easy and simple to handle, intuitive is strong, gear-driven process can be displayed intuitively, is beneficial to people and understands the gear drive principle.
