The model utility content
The purpose of this utility model provides a kind of parallel axes cam indexing mechanism with the worm and gear deceleration.
According to an aspect of the present utility model, a kind of parallel axes cam indexing mechanism with the worm and gear deceleration is provided, comprise casing, speed reducer and indexing mechanism, speed reducer connects indexing mechanism, and speed reducer and indexing mechanism are fixedly connected with casing.Thus, the parallel axes cam indexing mechanism that slows down with worm and gear has comprised the function of speed reducer and Cam indexing device, has effectively reduced volume.
In some embodiments, speed reducer comprises worm screw, worm gear and jack shaft, worm screw and casing jointing place are provided with the worm shaft bearing, the worm shaft bearing is connected with casing, worm and worm wheel are meshed, jack shaft and casing jointing place are arranged with middle bearing bracket, and middle bearing bracket is connected with casing, and worm gear set is located on the jack shaft and with jack shaft and is fixedly connected with.
In some embodiments, indexing mechanism comprises cam and calibration rotary roller, cam is fixedly connected with jack shaft, the calibration rotary roller comprises output shaft, index plate and roller, index plate is set on the output shaft and with output shaft and is fixedly connected with, and roller is fixedly connected with index plate, and cam is corresponding with roller, output shaft is positioned at the index plate both sides and is provided with the output shaft bearing, and the output shaft bearing is connected with casing.
In some embodiments, cam is two conjugate cams that become the mirror image symmetry.Thus, can make transmission more accurate.
In some embodiments, be provided with active chamber in the casing, cam, worm gear, index plate and roller all are located in the active chamber, and casing is assembly parts.
Description of drawings
Fig. 1 is that the utility model is with the structural representation of the side-looking direction of a kind of mode of execution of parallel axes cam indexing mechanism of worm and gear deceleration;
Fig. 2 removes the structural representation that speed reducer behind the worm screw and indexing mechanism are overlooked direction among Fig. 1;
Fig. 3 is the structural representation of roller among Fig. 1 and Fig. 2.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
Fig. 1 and Fig. 2 have schematically shown according to formation and the position relationship thereof of the utility model with a kind of embodiment of the parallel axes cam indexing mechanism of worm and gear deceleration.
Shown in Fig. 1,2 and 3, a kind of parallel axes cam indexing mechanism with the worm and gear deceleration comprises casing 1, speed reducer and indexing mechanism, and speed reducer connects indexing mechanism, and speed reducer and indexing mechanism are fixedly connected with casing 1.
Speed reducer comprises worm screw 2, worm gear 3 and jack shaft 4, worm screw 2 is provided with worm shaft bearing 5 with casing 1 jointing place, worm shaft bearing 5 is connected with casing 1, worm screw 2 and worm gear 3 are meshed, jack shaft 4 is arranged with middle bearing bracket 6 with casing 1 jointing place, middle bearing bracket 6 is connected with casing 1, and worm gear 3 is set on the jack shaft 4, and worm gear 3 is fixedly connected with jack shaft 4.
Indexing mechanism comprises cam 7 and calibration rotary roller, cam 7 is fixedly connected with jack shaft 4, the calibration rotary roller comprises output shaft 8, index plate 9 and roller 10, index plate 9 is set on the output shaft 8 and with output shaft 8 and is fixedly connected with, roller 10 is fixedly connected with and forms rolling pair with index plate 9, cam 7 is corresponding with roller 10, output shaft 8 is positioned at index plate 9 both sides and is provided with output shaft bearing 11, output shaft bearing 11 is connected with casing 1, jack shaft 4 is parallel with output shaft 8, is provided with active chamber in the casing 1, cam 7, worm gear 3, index plate 9 and roller 10 all are located in the active chamber, the part of worm screw 2 is in active chamber, and this part and worm gear 3 engagements.
The end of worm screw 2 is connected with the rotating shaft of motor, and when machine operation, the rotating shaft of motor drives worm screw 2 and rotates, worm screw 2 and worm gear 3 engagements, along with the rotation of worm screw 2, worm screw 2 drives worm gear 3 makes worm gear 3 drive jack shaft 4 rotations, 3 formation speed reducer of worm screw 2 and worm gear reach the purpose of deceleration.
When jack shaft 4 rotation, drive the cam 7 that is fixedly connected with jack shaft 4, cam 7 promotes the roller 10 on the index plate 9 when rotating along with jack shaft 4, the effect that index plate 9 is subject to roller 10 drives output shaft 8 rotations, drive the device work that is attached thereto during output shaft 8 rotation, realize the purposes such as interrupted division or stepping conveying.
