Abstract
The utility model relates to a friction synchronous direct drive waist-type roller clutch, which comprises a solar friction wheel, a planetary friction wheel, a waist-type eccentric roller position seat, a waist-type eccentric roller, a clutch body, a cylindrical wheel and a spline output shaft. Through the utility model, the synchronous direct driving of multiple waist-type eccentric rollers in fixed connection with the planetary friction wheel can be realized by using the solar friction wheel particularly, the gear transmission is replaced, the matching problem caused by processing errors of the waist-type eccentric roller is solved by using the sliding displacement of friction transmission, and the adaptive clutch conditions of each waist-type eccentric roller are guaranteed.
Description
Technical field:
The utility model is that a kind of gear directly drives the clutch with friction mode drive controlling waist type roller in the waist type roller clutch synchronously, especially can directly drive the waist type eccentric roller that is connected with epicyclic friction gear synchronously by the sun friction wheel that the control step motor connects, effectively utilized the characteristic of skidding of friction driving, prevented the rigidity of gear drive, the clutch characteristic that also has the clutch of waist type eccentric roller, make clutch system more can adapt to the needs of some specific uses, reach the purpose of controlling clutch.
Background technique:
Gear transmission in the existing gear direct-drive waist type roller clutch mode belongs to positive drive, just there is not slide displacement between driving tooth and the driven tooth, how many driven tooth driving tooth changes and just what changes by velocity ratio, in the synchronization control of a plurality of waist type eccentric rollers, each waist type eccentric roller all has machining error, adopt gear mode synchronous drive, the phenomenon that does not put in place that the clutch work that has puts in place stressed skewness can appear, in the machining error that can not mend reward waist type eccentric roller well.
The model utility content:
The purpose of this utility model provides a kind of friction and directly drives waist type roller clutch synchronously, realize directly driving the waist type eccentric roller that a plurality of epicyclic friction gears are connected synchronously with sun friction wheel, replace gear transmission, utilize the slide displacement between the friction driving, solve the matching problem of the machining error formation of waist type eccentric roller, guarantee the self adaption clutch condition of each waist type eccentric roller.
Its objective is such realization, stepper motor connects sun friction wheel in Fig. 1, epicyclic friction gear evenly distribute be installed in sun friction wheel around and form planetary friction and connect, the uniform positioning hole that waist type eccentric roller passes on the waist type eccentric roller positioning seat is connected with the epicyclic friction gear one, off-centre work circular arc by waist type eccentric roller between clutch body and the cylinder wheel forms controlled clutch and is connected, and it is that spline is connected that cylinder is taken turns with the spline output shaft.
Below in conjunction with embodiment Fig. 1, Fig. 2, Fig. 3 the working procedure that friction is directly driven waist type roller clutch synchronously is described; Sun friction wheel accurately controlled by stepper motor and a plurality of epicyclic friction gears rotations are directly driven in friction synchronously, replaced gear transmission, utilize the slide displacement between the friction driving, solve the matching problem of the machining error formation of waist type eccentric roller, guarantee the self adaption clutch condition of each waist type eccentric roller, waist type eccentric roller is driven by friction wheel, clutch work outputting power.
Below in conjunction with embodiment Fig. 1, Fig. 2, Fig. 3 the work that friction is directly driven waist type roller clutch synchronously is described.
