Abstract

一种往复箱中往复轴与轴套的配合结构,包括与装有偏心轮的连杆一端相驱接的往复轴及与往复轴相配的轴套,其特点是在往复轴下方的轴套配合表面沿轴向设有至少两条相对轴心呈扇角布置的沟槽,在沟槽内排列布设有滚珠,所述滚珠与往复轴接触面间为滚动配合。本实用新型由于采用了在往复轴下方的轴套配合表面沿轴向设置的至少两条以上的内排列布设有滚珠的沟槽,使往复轴与轴套间由原来的滑动配合变为滚动配合,不仅大大减少了两者间运动产生的摩擦带来的磨损,而且由于往复轴的重量由两排强度较高的滚珠承受,使往复轴与轴套间接触面积减少,这样更易润滑油沿轴表面集中到两条沟槽内,确保了两运动面间的润滑,从而延长了产品的使用寿命。

A matching structure between a reciprocating shaft and a shaft sleeve in a reciprocating box, including a reciprocating shaft driven and connected to one end of a connecting rod equipped with an eccentric wheel and a shaft sleeve matched with the reciprocating shaft, which is characterized in that the shaft sleeve below the reciprocating shaft cooperates The surface is axially provided with at least two grooves arranged at fan angles relative to the axis, and balls are arranged in the grooves, and the contact surface between the balls and the reciprocating shaft is a rolling fit. Because the utility model adopts at least two or more grooves arranged with balls arranged in the axial direction on the shaft sleeve matching surface below the reciprocating shaft, the original sliding fit between the reciprocating shaft and the shaft sleeve is changed into a rolling fit. Not only greatly reduces the wear caused by the friction caused by the movement between the two, but also because the weight of the reciprocating shaft is borne by two rows of high-strength balls, the contact area between the reciprocating shaft and the bushing is reduced, which makes it easier for lubricating oil to concentrate along the shaft surface In the two grooves, the lubrication between the two moving surfaces is ensured, thereby prolonging the service life of the product.

Description

The cooperating structure of reciprocating shaft and axle sleeve in a kind of reciprocal case
Technical field
The utility model relates to the reciprocal case that transmission of power is used, the cooperating structure of reciprocating shaft and axle sleeve in particularly a kind of reciprocal case.
Background technique
In existing reciprocal case transmission system, reciprocating shaft and shaft room adopt usually and are slidingly matched, and are abrasion state because reciprocating shaft is in for a long time with axle sleeve when work, cause the reciprocal case drive part life-span shorter, at above-mentioned existing problems.Chinese patent ZL01242984.8 discloses a kind of rollaway type pulsion stroke case, and as shown in Figure 6, it mainly is made of belt pulley 1, casing 2, main shaft 3, inside and outside eccentric mass 4A, 4B, rolling bearing 5, front axle 6 and rolling bearing 7.Though this design has overcome existing deficiency in the former design, reduced the friction between reciprocating shaft and the axle sleeve, but also can see that from this design proposal the weight of main transmission component in the stroke case is by roller bearings, so not only can influence the life-span of bearing because of the dynamic load effect of bearing, and also exist complex structure, volume is big, cost is high deficiency from the general arrangement.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of by changing axle and shaft room matching relationship, it is increased the service life and reciprocal case that the structure of signing an undertaking is simple, reasonable in design in the cooperating structure of reciprocating shaft and axle sleeve.
The technical solution of the utility model is: the cooperating structure of reciprocating shaft and axle sleeve in a kind of reciprocal case, comprise and the axle sleeve that eccentric connecting rod one end drives the reciprocating shaft that connects mutually and matches with reciprocating shaft is housed, be characterized in that the axle sleeve matching surface below reciprocating shaft is provided with the groove that at least two relative axle center are fan angle layout vertically, in groove, arrange and be laid with ball, cooperate for rolling between described ball and reciprocating shaft surface of contact.
Further, the cross section bottom notch of falling the trapezoidal upper of above-mentioned groove is rectangular, is provided with the maintenance support between groove and ball.
Further, the above-mentioned groove that is provided with vertically is two, and formed fan angle, its relative axle center is 45~75 degree.
The utility model is owing to adopted the interior arrangement more than at least two that is provided with vertically at the axle sleeve matching surface below the reciprocating shaft to be laid with the groove of ball, making reciprocating shaft be become to roll by original being slidingly matched with shaft room cooperates, the wearing and tearing that the friction that not only having significantly reduced moves between the two produces brings, and owing to the weight of reciprocating shaft is born by the higher ball of two row's intensity, reciprocating shaft and shaft room area of contact are reduced, easier like this lubricant oil focuses in two grooves along the axle surface, guarantee lubricating between two moving surfaces, thereby prolonged the working life of product.
Below in conjunction with accompanying drawing the utility model is further described:
