Abstract
The utility model relates to a gear roller-typed unidirectional brake device, which is applied to the clutch of a full auto washing machine. The device is provided with a cylindrical outer housing, the bore surface of which is evenly distributed with tapered planes which are provided with circular arc grooves and inclined toward the same direction, and is also provided with the same number of pin rollers as circular arc grooves fixed by retainers. Spring leaves are arranged between adjacent pin rollers. The two end faces of the outer housing are also embedded with sealing rings. The utility model is characterized in that the cylindrical outer housing forms a gear shape, and carries out location fit and clearance fit with the ring gear of a frame. The spring leaf forms an S shape. The number of teeth of the outer housing is 25, and the modulus is 2. The utility model can adjust concentricity freely, reduce noise and cost, and prolong the service life of washing machines.
Description
The utility model relates to the braking device on the mechanical transmission, particularly is applied to gear roller formula one-way braking means supporting on the full auto washing machine clutch.
Present automatic washing machine is realized two kinds of operations of the washing and two rotating speeds that dewater with a motor.General speed-reducing clutch interior planetary reducer and the clutch of adopting realized.Insert in the transmission cover of planetary mechanism with spline at impeller axle one end, between the rolling bearing on transmission cover and the impeller axle, braking device is arranged.Two kinds of modes of braking were arranged in the past, and a kind of is to adopt to embrace spring arrangement; Another kind is to adopt the overrunning type clutch apparatus, and its purpose all is to allow driving component to change towards a direction, then brakes during counter-rotating.Have many shortcomings during actual motion, to exist running noises big as embracing a spring arrangement, is higher than 60 decibels, and embrace a spring and easily make a surface abrasion, and working life is short, and the concentricity of embracing spring and axle simultaneously is difficult for guaranteeing.And the employing free wheel device, because complex process, especially spring sheet shape are very complicated, precision be cannot say for sure to cause up-to-standard rate to be difficult to reach absolutely by card, and simultaneously because it will cooperate with bearing, manufacture cost is bigger, and the past relies on high price from external import; Also exist shell too thin, bad mechanical strength, carry-over moment is little, shortcomings such as leakage of oil.
The structure of free wheel device has cylinder blanket, be evenly distributed with the tapered plane to a direction inclination of band arc groove on its inner hole surface, according to the identical number of arc groove number the fixing roller of retainer is installed, between the adjacent roller spring is installed, also embedded seal ring at the shell two ends.
The purpose of this utility model is to overcome above-mentioned shortcoming, further improves on the basis of free wheel device, is provided for the gear roller formula one-way braking means on the full auto washing machine clutch.
The utility model is finished as follows: the shell barrel surface is made gear shape, and cooperate with support ring gear geocoded activity, and the spring sheet between the roller is made S type shape.
The gear number of teeth on the shell is 25, and modulus is 2.
The conventional art that the utility model compares has following advantage: owing to adopt the gear shape shell to cooperate with support ring gear geocoded activity, therefore can save original bearing that cooperates with it, escapable cost 1..But and free adjustment concentricity; 2. reducing noise has only the 45-50 decibel; 3. long service life; 4. spring sheet simple shape, easy processing.
Further describe below in conjunction with accompanying drawing.
Fig. 1 is a gear roller formula one-way braking means.
Fig. 2 is the sectional view of Fig. 1.
With reference to Fig. 1, shell (1) is made gear shape, be used on the one hand cooperating with the support ring gear geocoded activity of engineering plastics compacting, can freely adjust the concentricity with axle, reducing noise also can reduce cost simultaneously, cancel the bearing of original cooperation, thereby reduce cost greatly.And eliminate and embrace the wearing and tearing of spring, improve working life axle.S type spring sheet (3) is installed between roller (2) is adjacent.Chip architecture of the spring on original free wheel device and shape are very complicated, and manufacturing process is difficult to grasp.Adopt S type spring sheet (3), manufacturing process is simple, and is easy for installation, functional, and roller (2) is movable fixing by retainer (4), when axle clockwise rotates, roller (2) in arc groove, this moment hole internal diameter maximum, axle rotates.When axle reverses, drive roller (2) and go up rolling to tapered plane (5), then the hole internal diameter dwindles, and causes axle to be pressed from both sides tighter and tighter by roller, and axle can not be rotated, so only allow axle to clockwise rotate, plays the one-way brake effect.The promptly interior axle rotation direction of the direction of arrow among the figure.
The number of teeth on the shell (1) is 25, and modulus is 2.Rubber seal 6 among Fig. 2, in gear shape roller one-way braking means both sides, play the effect that prevents leakage of oil.Shell (1) roller (2) adopts bearing steel material, and retainer (4) adopts engineering plastics such as polyoxymethylene manufacturing.
Claims (2)
1, gear roller formula one-way braking means, cylinder blanket (1) is arranged, be evenly distributed with the tapered plane (5) that tilts to an aspect of band arc groove on its inner hole surface, according to the identical number of arc groove number the fixing roller (2) of retainer (4) is installed, spring sheet (3) is installed between the adjacent roller (2), also embedded seal ring (6) in shell (1) both ends of the surface, it is characterized in that:
A, cylinder blanket (1) are gear shape, cooperate with support ring gear geocoded activity;
B, said spring sheet (3) shape are the S types.
2, according to the said one-way braking means of claim 1, it is characterized in that the number of teeth on the shell (1) is 25, modulus is 2.
