摘要： A cam unit comprising a main cam; a first auxiliary cam provided in contact with the main cam; a second auxiliary cam provided in contact with the first auxiliary cam; a rod provided between the main cam and the second auxiliary cam and having a slenderly shaped hole in which the peripheral portion of the first auxiliary cam is located in contact with the rod so that the rod is swung while being guided by the first auxiliary cam; a motion transmission means secured to the rod and located on the peripheral portion of the main cam so as to move the rod in accordance with the contour of the main cam; a jump prevention means secured to the rod and located on the peripheral portion of the second auxiliary cam so as to prevent the motion transmission means from jumping from the main cam; and a shaft extending through all the cams. A positive cam is constituted by the main cam, the auxiliary cams and the rod without guiding a driven member to straightly move it. A motion is directly transmitted to a swinging member by the cam unit.

摘要： A motion transforming apparatus for transforming a continuous rotary motion of an input shaft into a motion of a predetermined type of an output shaft through a motion transmitting cam device. The fluctuating torque loaded on the input shaft by the motion transmitting cam device is compensated by torque compensating cam device and pneumatic cylinder device for applying a load on the torque compensating cam device. The pneumatic cylinder device includes a cylinder and a piston, and the pressure of the gas in the cylinder compressed or expanded by the reciprocating piston acts on the torque compensating cam device, thereby applying a compensating torque on the input shaft.

摘要： A cam-driven reciprocating slide assembly for reciprocating a carriage of a machine, particularly a quilting machine, includes a frame member which is mounted for slidable movement along a linear direction. A pair of opposed contact rollers are mounted on the frame member and positioned to define a space along the predetermined direction for receiving a rotary design or pattern cam disc therebetween. One of the contact rollers is mounted on the frame member and adjustably positionable along the predetermined direction. The other contact roller is mounted on a pretensioning apparatus which comprises a housing mounted on the frame member and a resiliently mounted piston arrangement slidably movable within the housing. The contact roller mounted on the pretensioning apparatus is fixed on the piston. With this arrangement, rotary movement of the design cam disc with the periphery of the latter in contact with the contact rollers imparts reciprocatory motion to the slide assembly. The cam receiving space is variable by the yielding movement of the resiliently mounted contact roller, whereby a design cam disc disposed in operative relation between the rollers causes the resiliently mounted roller to yield in response to peripheral surface imperfections on the cam disc.
摘要翻译： 用于使机器的托架特别是绗缝机往复运动的凸轮驱动的往复运动滑动组件包括框架构件，其被安装成沿着线性方向可滑动运动。 一对相对的接触辊安装在框架构件上并定位成沿着预定方向限定一个空间，用于接收其间的旋转设计或图案凸轮盘。 接触辊中的一个安装在框架构件上并沿着预定方向可调节地定位。 另一个接触辊安装在预张紧装置上，该预张紧装置包括安装在框架构件上的壳体和可在壳体内可滑动地移动的弹性安装的活塞装置。 安装在预张紧装置上的接触辊固定在活塞上。 利用这种布置，设计凸轮盘与其后端的周边与接触辊接触的旋转运动使往复滑动组件运动。 通过弹性安装的接触辊的屈服运动，凸轮接收空间是可变的，由此在辊之间以可操作的关系设置的设计凸轮盘使得弹性安装的辊响应于凸轮盘上的周边表面缺陷而屈服。
