Description

A kind of Novel index plate

Technical field

Digit ctrol machine tool field is the utility model is related to, espespecially a kind of Novel index plate.

Background technology

Index dial in the market based on Worm Wheel System, this structure reversion when must leave it is certain between Gap, this can cause angle precision during this index dial rotating deviation to be present, exist for high precision part crudy Unstability, it is difficult to ensure yields, worm gear is often bronze with manufacture material in addition, is generally deposited which results in worm gear structure Easy to wear and integral rigidity is poor the shortcomings that, in machining heavy-type workpieces, loss of significance is very fast, it is necessary to regular Adjustment precision.

Utility model content

To solve the above problems, the utility model provides a kind of zero back clearance transmission, the good Novel index plate of integral rigidity.

To achieve the above object, the utility model, which adopts the following technical scheme that, is：A kind of Novel index plate, including case Body, roller, force-output shaft, YRT turntables bearing, cam and workbench, the force-output shaft are located in casing, and the workbench passes through lock Tight screw is fixedly connected with casing, and the turntable on the workbench is rotatably connected with force-output shaft, and the YRT turntables bearing is worn out Power axle and the rear for being located at workbench, the roller wear force-output shaft and are located at the rear of YRT turntable bearings, and the cam is located at It is connected below roller and with roller rolls.

Preferably, in addition to eccentric bushing and eccentric bushing bearing, the eccentric bushing bearing are fixed is located at casing respectively In the bearing block mounting hole of two sides, the eccentric bushing is respectively provided in eccentric bushing bearing.

Preferably, the both ends of the cam are each passed through the eccentric bushing of both sides and are rotatably connected with eccentric bushing.

Preferably, in addition to oil sealing, the oil sealing are located in the both ends of force-output shaft and cam respectively.

The beneficial effects of the utility model are：Cam both ends, can be real by eccentric bushing regulation and the fit precision of roller Existing zero back clearance is driven and applies certain precompressed, simultaneously because having used YRT turntable bearings, greatly reduces the Product Assembly time, Improve the segmentation precision and integral rigidity of index dial, it is possible to reduce the maintenance cost of index dial, and improve production efficiency.

Embodiment

Refer to shown in Fig. 1-4, the utility model is on a kind of new gapless index dial of 2 cam of roller 5, including casing 1st, roller 2, force-output shaft 3, YRT turntables bearing 4, cam 5 and workbench 6, the force-output shaft 3 are located in casing 1, the workbench 6 are fixedly connected by lock-screw with casing 1, and the turntable on the workbench 6 is rotatably connected with force-output shaft 3, the YRT turntables Bearing 4 wears force-output shaft 3 and is located at the rear of workbench 6, and the roller 2 wears force-output shaft 3 and is located at YRT turntables bearing 4 Rear, the cam 5 are located at the lower section of roller 2 and rolled with roller 2 and connected.

It is solid respectively as a kind of preferred embodiment, in addition to eccentric bushing 7 and eccentric bushing bearing 8, the eccentric bushing bearing 8 Surely it is located in the bearing block mounting hole of two sides of casing 1, the eccentric bushing 7 is respectively provided in eccentric bushing bearing 8.

As a kind of preferred embodiment, the both ends of the cam 5 are each passed through the eccentric bushing 7 of both sides and rotated with eccentric bushing 7 Connection.

As a kind of preferred embodiment, in addition to oil sealing, the oil sealing is located in the both ends of force-output shaft 3 and cam 5 respectively.

Operation principle：Cam 5 rotates, and due to being driven between cam 5 and roller 2 in a manner of oil film, enables roller 2 Enough to be rotated with smaller abrasion, roller 2 drives force-output shaft 3 to rotate, due to the effect of YRT turntables bearing 4, the energy of force-output shaft 3 It is enough stably to rotate, so that the turntable on workbench 6 rotates more stable, make segmentation precision more accurate.

Embodiment of above is only that preferred embodiment of the present utility model is described, not to the utility model Scope be defined, on the premise of the utility model design spirit is not departed from, this area ordinary skill technical staff to this The various modifications and improvement that the technical scheme of utility model is made, the guarantor that claims of the present utility model determine all should be fallen into In the range of shield.
