Abstract
The utility model relates to a clutch bracket. A counter bore for mounting a bearing is arranged on the inner wall of a roof board of a hood bracket. The clutch bracket is characterized in that a self-aligning ball bearing and an oil seal are arranged in the counter bore by interference fit in turn; one side of the counter bore is provided with a groove; a pressure plate of the oil seal is tightly fixed in a bore mouth of the counter bore; and the oil seal and the pressure plate of the oil seal are respectively provided with a through hole for a driven shaft to run through. When the clutch bracket operates, the clutch bracket can keep the coaxiality of the driven shaft and the bracket consistent, and has the advantages of simple assembly and the improvement of the qualification rate of the clutch.
Description
Technical field
The utility model relates to the engine clutch accessory, particularly a kind of clutch-pedal support of motorcycle engine.
Background technique
Clutch-pedal support is used to support driven shaft, is equipped with the belt transmission primary clutch that is used for transferring power on the driven shaft.The span of existing clutch-pedal support is big, and the narrower in width of support, affected by force is easy to generate distortion after the moulding, also influences installation precision simultaneously.During engine operation, the radial effect power that the belt gear primary clutch is produced makes the coaxality of driven shaft and support be affected easily.In addition, because rack-mount supporting driven shaft is a deep groove ball bearing, the installation precision of deep groove ball bearing requires high, when the coaxality of support and driven shaft is inconsistent, can't adjust automatically, after the motor assembling, support and driven shaft coaxality change greatly, when engine operation, because of the coaxality that can not guarantee driven shaft and bearing produces friction, make the clutch can't clutch or clutch produces abnormal sound, vibrations be big, and the up-to-standard rate of clutch is very low.
Summary of the invention
The purpose of this utility model is to provide a kind of clutch-pedal support of debugging, and it is in when work, can driven shaft remains consistently with the coaxality of support, and has the advantage of the simple and raising clutch up-to-standard rate of assembling.
The purpose of this utility model is achieved in that the top inwall of hood pedestal is provided with and is used for bearings mounted counterbore, it is characterized in that: selfaligning ball bearing, oil sealing are interference fitted in the described counterbore successively, one side of counterbore is provided with groove, the oil sealing pressing plate is anchored on the aperture of counterbore, is equipped with the via hole that passes for driven shaft on oil sealing and the oil sealing pressing plate.
Further technological scheme of the present utility model is, described oil sealing pressing plate one end is provided with the portion of turning back, and the described portion of turning back inserts in the other groove of counterbore, and the oil sealing pressing plate the other end is fastening by bolt and support.
Described counterbore is a shoulder hole, and the selfaligning ball bearing interference fit is in the big end of shoulder hole, and is spacing by the step of step hole.
Adopted such scheme, selfaligning ball bearing and oil sealing are interference fitted in this bearing hole successively, because selfaligning ball bearing can be adjusted angular deviation and angular motion between driven shaft and bearing twice shaft axis automatically, but its center adjusting value can reach 3 degree, therefore, no matter be the coaxiality deviation that causes driven shaft and support by support self span greatly, or the driven shaft that causes in the installation process and the coaxiality deviation of support, or motor is subjected to the driven shaft that the radial effect power of belt primary clutch produces and the coaxiality deviation of support in the course of the work, automatically adjust by selfaligning ball bearing, all can make driven shaft remain consistent with the coaxality of support.Therefore, the utility model has improved the running accuracy of clutch driven shaft, has reduced the starting torque of clutch driven shaft, has guaranteed the smoothness of operation of clutch driven shaft, eliminate the clutch abnormal sound, thereby improved the performance of motor and the up-to-standard rate of once installing.
The oil sealing pressing plate is anchored on the aperture of bearing hole, can makes firm being positioned in the bearing hole of oil sealing, to guarantee the sealing of oil sealing to lubricant oil.
The utility model is simple in structure, and is easy to assembly, and practical advantage is arranged.
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the assembly structure figure of the utility model and clutch.
In the accompanying drawing, 1 is support, and 1a is a mounting hole, and 2 is selfaligning ball bearing, and 3 is oil sealing, and 4 is the oil sealing pressing plate, and 5 is bolt, and 6 is driven shaft, and 7 is the belt transmission primary clutch.
Embodiment
With reference to Fig. 1 and Fig. 2, this clutch-pedal support 1 is a cover body, and the top inwall of support 1 is provided with bearings mounted counterbore, and described counterbore is a shoulder hole, and a side of counterbore is provided with groove, and the port of frame bottom is provided with the mounting hole 1a that is used to assemble this support.Selfaligning ball bearing 2 and oil sealing 3 are interference fitted in the counterbore successively, and oil sealing is used for the lubricant oil in the seal lubrication selfaligning ball bearing.Selfaligning ball bearing 2 interference fit are in the big end of shoulder hole (counterbore), and are spacing by the step of step hole, make selfaligning ball bearing can adapt to the bearing of angular deviation and angular motion between the twice shaft axis automatically, but its center adjusting value maximum can reach 3 degree; The small end of counterbore passes for driven shaft, to improve the reliability of assembling.Oil sealing pressing plate 4 is anchored on the aperture of bearing hole, and oil sealing pressing plate 4 is used for oil sealing 3 axial limitings., oil sealing pressing plate 4 one ends are provided with the portion of turning back, and in the groove that the portion's of turning back insertion counterbore one side of oil sealing pressing plate is established, the oil sealing pressing plate the other end is fastening by bolt 5 and support 1.Be equipped with the via hole that passes for driven shaft on oil sealing 3 and the oil sealing pressing plate 4, driven shaft 6 one ends are riveted on the clutch housing, and the via hole that its other end passes oil sealing 3 oil sealing pressing plates 4 cooperates with selfaligning ball bearing.Belt transmission primary clutch 7 is installed on the driven shaft 6.
During engine operation, clutch-pedal support can be adjusted the driven shaft that assembled and the coaxality of support automatically, guarantees the smoothness of operation of clutch driven shaft, has eliminated the clutch abnormal sound, and the once installation up-to-standard rate of motor improves greatly.
The utility model is used for three, the clutch-pedal support of four-wheel motor cycle, has above-mentioned effect same.
Though the utility model discloses as above with preferred embodiment; right its is not in order to limit the utility model; any person of ordinary skill in the field; in the spirit and scope that do not break away from the utility model; when can doing a little change and improvement, so the protection domain of the utility model is as the criterion when looking the claim person of defining.
