Abstract
The invention provides a conical ring stepless speed change device. A pair of cones are axially parallel and are arranged in a reversed mode, rings are arranged on the outer sides of the two cones, the rings and the cones are pressed by pressing devices in the cones, and friction between the rings and the cones is used for transferring power. By means of the speed regulation device, the positions of the rings on the cones are changed, and different speed ratio changes are achieved. Due to the fact that the position change of the rings on the cones is continuous, stepless speed change can be achieved. The device has the advantages of being simple in structure, stepless in speed change and large in transmitted torque range.
Description
Technical field
The present invention relates to a kind of stepless speed changes devices, be particularly useful for mechanical conical ring stepless speed changes devices.
Background technique
In US Patent No. 1709346, set forth a kind of parallel axes and be mutually inverted cone, utilized the conical ring stepless speed changes devices that encircles transferring power and speed change between cone.Utilize and be mutually inverted ring between cone clamping cone and cone, utilize the friction carry-over moment of ring between cone and cone.Afterwards for transmitting larger torque and increasing the service life, people increase friction factor in cone and interannular a kind of traction of annotating, and reduce the wearing and tearing between conical ring.Actual conditions are to bore in encircling only one side power transmission among a small circle, so transmitting torque is limited due to arbitrary.
Summary of the invention
The present invention is to provide pair of parallel axle and is mutually inverted cone, and ring, in the outside of two cones, will be encircled with cone and be compressed by the hold down gag in cone, by the frictional force transferring power between ring cone.By arrangements for speed regulation, change the position of ring on cone, realize the variation of different speed ratios.Because the change in location of ring on cone is continuous, so can realize stepless change.
The invention has the beneficial effects as follows that speed change gear is simple in structure, stepless change is can transmitting torque scope larger.

Embodiment
Embodiment shown in Fig. 1 is that parallel axes is inverted the new conical ring stepless speed changes devices of cone mutually.Cone 1 is parallel with cone 2 axis, is mutually inverted fixed installation, between two cones, has an equidistant gap.One of them cone is power input shaft, and another cone is pto＝power take-off.Direction as shown ring 3 and two axis of cone lines are arranged vertically, and ring is tangent with two cone outer side surfaces.Cone 2, under spring 6 effects, will encircle with two cone outer side surfaces and compress, and utilize the friction transferring power between ring and the conical surface.By controlling arrangements for speed regulation 4, can change the position of ring on cone, realize the variation of different speed ratios.Because the change in location of ring on cone is continuous, so stepless change that can implement device.
Axle 5 and 2 of cones have spline joint, and the two mutual transferring power, can move to axial again.
For improve hauling ability, the traction of can annotating between conical ring.
