The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is elaborated.Should be understood that the specific embodiment described herein only is used for description and interpretation the utility model, is not limited to the utility model.
As depicted in figs. 1 and 2, the utility model provides a kind of transmission shaft center support, this transmission shaft center support comprises supporting base 1 and the cushion rubber 2 that is arranged in this supporting base 1, be respectively arranged with two first bolts hole on two sidewalls of described supporting base 1, a bolt hole in described two first bolts hole is a slotted hole.
According to above technical scheme, because supporting base 1 has slotted hole, make the adjustable angle of transmission shaft center support in the fitting process of transmission shaft and transmission shaft center support, therefore can solve assembling back cushion rubber 2 torsional deflections effectively even deviate from supporting base 1 and cross member of frame is hung miscellaneous problem.
Preferably, described slotted hole is oblong aperture or slotted hole.The slotted hole of shape is processed easily like this, can reduce the difficulty of processing and the tooling cost thereof of described supporting base 1.Oblong aperture or slotted hole typically refer to straight slotted hole, and in fitting process, described slotted hole (as, oblong aperture or slotted hole) madial wall and bolt between generally have certain clearance, by this gap, make described transmission shaft center support in certain angular range, to rotate.
Preferably, described slotted hole also can be circular arc, and the center of circle of this circular arc is the center of another bolt hole.Described transmission shaft center support can be rotated in a bigger angular range.Certainly, also be not limited thereto, described slotted hole also can be for the hole of other type, as elongated hole, as long as can make the angle of described transmission shaft center support to regulate.
Described cushion rubber 2 can be used for damper element of the present utility model for any one, as long as can play buffer action and have enough load-carrying capacitys.Preferably, described cushion rubber 2 is a rubber pad.Rubber pad is common damper element, and it not only has desirable buffering effect, and cheap, is convenient to change, and can reduce the manufacturing cost and the use cost of described transmission shaft center support effectively.
Preferably, described rubber pad comprises the salient 22 that is used for bearings mounted ring part 21 and protrudes from the excircle of described ring part 21, and described protrusion 22 is connected with described supporting base 1.Such rubber pad not only has good damping effect, can also in time the heat that produces in the described transmission shaft center support working process be come out simultaneously, can prolong the service life of described transmission shaft center support.
