Description
Technical field
The utility model relates to a kind of wheel, particularly can only be to the unidirectional rotating wheel of a direction rotation.
Background technique
On present military machinery or Transport Machinery and toy were made, the wheel of selecting for use was not mostly realized the wheel of controllable one-way rotation.Especially in children toys, sport-specific products, to have the wheel that uses now all be the wheel that can't realize one-way rotation, the wheel of the roller shoes of for example often seeing (roller skate) etc., all can not realize the uniaxially purpose that turns round forward, often be to the beginner, especially children are easy to generate and slip, especially relate to the situation on gradient ground.Certainly also select for use ratchet or free wheel device form to change in the hope of one-way shaft or the wheel commentaries on classics, but because its complex structure and cost are comparatively expensive.
Summary of the invention
For overcome existing Transport Machinery and toy make in selected wheel can not the low-cost characteristics that realize controllable one-way rotation, the utility model provides a kind of unidirectional rotating wheel, this unidirectional rotating wheel can be according to the function needs of Transport Machinery and toy product, realize cheaply can only unidirectional running function.
The technological scheme that its technical problem that solves the utility model adopts is:
A kind of unidirectional rotating wheel, include the circular rotary wheel body, bearing outer race wheel cover, rolling bearing, the endoporus axle, circular rotary wheel body and the outer ring socket of bearing outer race wheel cover, bearing outer race wheel cover inner ring and housing washer socket, rolling bearing inner ring and endoporus axle socket-connect, fixed cover is connected to matrix on the described endoporus axle, matrix outer and the socket of bearing outer race wheel cover inner ring, matrix is axially inboard to be connected with rolling bearing, the matrix outer is provided with groove, the groove vertical plane is provided with spring nest hole, the spring nest is provided with spring in the hole, the groove transverse plane is provided with needle roller, and the axial outside of matrix is provided with catch, by the endoporus axle matrix is fixed in the interior edge of bearing outer race wheel cover.Described groove becomes even even number to distribute on matrix.Described matrix and endoporus axle can be integral.
On the architecture basics of existing forward, reverse uncontrollable rolling bearing wheel, by additional matrix and the needle roller established, this matrix and needle roller, bearing outer race wheel cover can be realized the auto lock function, guarantee that this wheel can only one-way rotation.For guaranteeing the position relation between matrix and needle roller, spring, the bearing outer race wheel cover, by at the axial outside of matrix close-coupled catch, this catch is socketed on the endoporus axle, can be by the screw thread on the endoporus axle, with nut catch and matrix are carried out close-coupled, also can be provided with internal thread at catch and closely connect, guarantee one-way wheel in movement process, the relative position relation between matrix and needle roller, spring, the bearing outer race wheel cover is constant.
When circular rotary wheel body postive direction is rotated, because bearing outer race wheel cover oblong web postive direction together rotates, make needle roller push spring to, because the space between needle roller and groove transverse plane, the bearing outer race wheel cover is enough big, the rotation of circular rotary wheel body freely.And when circular rotary wheel body during to counter-rotation, then needle roller rolls outward along the spring direction with runner bearing outer race wheel cover, folder is tight more more between groove transverse plane and bearing outer race wheel cover then to make needle roller, has realized the self-locking effect at last, so the circular rotary wheel body can't rotate.Thereby realized the purpose of one-way rotation, because construction costs such as this matrix, spring, catch are very low, cost of the present utility model is also very low, has reached goal of the invention.
The utility model core members is the geometry accuracy of form and position of matrix and the concentricity precision of axle.
In order to guarantee the feasible of technology implementation.The utility model can be divided into two kinds of metal split and overall structures.Can select for use plastic material to cooperate very tight disposable extruding with metal sheet as required.Scheme one: central shaft and matrix are processed respectively, and then fitted in a body and function.Scheme two: integral body is reprocessed the matrix geometrical shape after being processed into one.Scheme three: plastics cooperate extruding with metal sheet.
The beneficial effects of the utility model are, this unidirectional rotating wheel can be according to the function needs of Transport Machinery and toy product, the function that realization can only unidirectional running.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a sectional view of the present utility model.
Fig. 2 is an assembly structure schematic representation of the present utility model.
Among Fig. 1,1 circular rotary wheel body, 2 bearing outer races wheel cover, 4 endoporus axles, 5 matrix, 6 groove vertical planes, 7 springs, 8 groove transverse planes, 9 needle rollers, 11 spring nest holes.
