The sliding and rolling key structure comprises a supporting bearing, the supporting bearing fixedly supports a fixed cone disc, the fixed cone disc is inserted in a center hole of a movable cone disc, and steel balls and combined keys are arranged in the fixed cone disc plane key grooves. The sliding and rolling key structure combining the fixed cone disc plane key grooves and the movable cone disc is suitable for transport carriers (like vehicles, airplanes and ships), petroleum machinery, textile machinery and other energy-saving and speed-regulating devices (like wind power generators).

Description

Determine the sliding scroll key structure of cone dish plane keyway and mantle dish combined type

Technical field

The utility model relates to the sliding scroll key of a kind of combined type and planar slot, and one is determined cone dish plane keyway and the sliding scroll key structure of mantle dish combined type specifically, for the slip of transmitting torque situation.

Background technique

Continuously variable transmission device can solve effective coupling of kinetic energy and potential energy, is also the bridge of input and output.Determining the sliding scroll key of cone dish plane keyway and mantle dish combined type is the main dynamically key components and parts of speed change in stepless speed variator, utilize the sliding rolling keyway of combined type mobile mantle dish in the situation that of transmitting torque, reduce the iron loss of mechanical system, in the prolonged mechanical life-span, this structure has well processed manufacturability.

All there are many shortcomings in the stepless speed variator cone dish keyway of existing three types;

(1) steel ball keyway, control accuracy requires high, and manufacture cost is very large, and part difficulty of processing is large, and part up-to-standard rate is low, repairs difficulty.

(2) cylinder keyway, frictional force causes slippage not smooth, affects instant speed change, and circular groove difficulty of processing is very large, and part up-to-standard rate is low.

(3) two cone dishes adopt inside and outside spline, are difficult to reconditioning after heat treatment, during work slippage not smooth, machining accuracy is high.

Above-mentioned three kinds of sliding keyways, mobile poor accuracy, needs special plane to produce, and manufacture cost is large, maintenance difficult.

Model utility content

In order to overcome the deficiencies in the prior art, the utility model provides a kind of determine cone dish plane keyway and the sliding scroll key structure of mantle dish combined type, comprise block bearing, described block bearing fixed bearing is determined cone dish, in the described center hole of determining cone dish insertion mantle dish, steel ball and bond structure are arranged on the described plane keyway of determining cone dish.

Further, described bond structure is special-shaped key.

Further, described bond structure is round key and needle roller.

Further, also comprise back-up ring, the steel ball in the fixing described plane keyway of described back-up ring.

Further, described determine cone dish and mantle dish composition can together with the Cone Disc assembly that rotates.

Of the present utility modelly determine the sliding scroll key structure of cone dish plane keyway and mantle dish combined type and be applicable to traffic delivery means (vehicle, aircraft, boats and ships), petroleum machinery, textile manufacturing machine and other energy-saving speed regulating equipment (wind-driven generator).

By mobile mantle dish under External Force Acting, change V-shaped groove width, realize speed regulating control effect, the utility model guarantees the stationarity of mantle dish in moving process.By steel ball two ends with rolling form location, by special-shaped column piece (or garden post adds needle roller key) transmitting torque, than existing cone dish decrease machining cost more than 30%.

The utility model adopts aggregate motion mode, does not need special plane processing.Only adopt tratitional technology, use common plane grinding machine to process, simplify the mode of production, avoided complicated technique and inefficient special purpose grinder, reduce investment.The utility model adopts plane or line contact power transmission, and Redundancy Design, expands the scope of transmitting kinetic energy, meet the required driving torque of various road conditions, processing method is very simple, and making cost per unit is other 2/3rds, keep in repair very convenient, to manufacture and maintenance environment less demanding.
