Specific implementation mode

Below in conjunction with the accompanying drawings and specific embodiment the utility model is described in further detail.

It please refers to Fig.1, Fig. 2, the claimed wheel-type incremental-rotating coder of the utility model, including the first wheel 10, the Second wheel 20 of opposite first wheel 10 setting, the worm screw 30 being set between the first wheel 10 and Second wheel 20, with snail Bar 30 be connected turbine 40, and for receives the first wheel 10 and Second wheel 20 rotation when signal encoder 50.

The worm screw 30 includes two interconnecting pieces 31 for being connected and fixed with the first wheel 10 and Second wheel 20, and Gear part 32 between two interconnecting pieces 31.That is, the worm screw 30 of the present embodiment and the first wheel 10 and second are taken turns It is fixedly connected between son 20.

Two interconnecting pieces 31 on the worm screw 30 of the present embodiment and the first wheel 10 or Second wheel in the present embodiment Between 20 fixation is attached with wheel limit plunger 61 and hexagon socket countersunk flat cap head screw 62 respectively.

Specifically, the wheel limit plunger 61 is out of, wheel hole 120 that be inserted into the first wheel 10 laterally outside, so Wheel limit plunger 61 is passed through with hexagon socket countersunk flat cap head screw 62 and offered with corresponding on corresponding interconnecting piece 31 on worm screw 30 afterwards Threaded hole (not shown) is spirally connected, and then realizes the fixed company on worm screw 30 between corresponding interconnecting piece 31 and the first wheel 10 It connects.Similarly, being fixedly connected between another interconnecting piece 31 and Second wheel 20 on worm screw 30 is realized.

Further, the wheel limit plunger 61 is inserted into the first wheel 10 or Second wheel 20 is got on the bus wheel bore 120 Periphery wall is arranged conical surface shape, and is contacted with the get on the bus hole wall of wheel bore 120 of first wheel 10 or Second wheel 20. That is the wheel limit plunger 61 is inserted into the first wheel 10 or Second wheel 20 is got on the bus in wheel bore 120, it can be by the first round The get on the bus hole wall of wheel bore 120 of son 10 or Second wheel 20 limits, that is, realizes wheel limit plunger 61 and the first wheel 10 Or the limit assembly between Second wheel 20.And then it realizes the present embodiment and is being limited across wheel with hexagon socket countersunk flat cap head screw 62 Position plug 61 and while be connected and fixed between interconnecting piece 31 on worm screw 30, first wheel 10 or Second wheel 20 and snail Bar 30 is connected and fixed.

In the present embodiment, the turbine 40 is provided on the central shaft 51 of encoder 50, and relative to encoder What 50 central shaft 51 was fixed along the circumferential direction of turbine 40.Specifically, the turbine 40 is to be socketed in encoder On 50 central shaft 51, and fixed in such a way that keyway coordinates with the central shaft of the encoder 50 51.

On the other hand, the grinding tooth of the turbine 40 and the grinding tooth in 30 gear portion of worm screw are intermeshed, in the present embodiment, The turbine 40 is provided in the underface in 30 gear portion 32 of the worm screw, and is nibbled with the gear part 32 on worm screw 30 It closes.

From the foregoing, it will be observed that the wheel-type incremental-rotating coder of the present embodiment is when in use, the first wheel 10 and Second wheel 20 rotation can drive worm screw 30 to be rotated simultaneously, and cooperation is engaged due to the gear part 32 on worm screw 30 and between turbine 40 , so the worm screw 30 of rotation can drive turbine 40 to be rotated, and then rotation drive is carried out to the central shaft 51 on encoder 50 Dynamic, when realizing the first wheel 10 and the rotation of Second wheel 20 with this, the encoder 50 can carry out the input of signal, that is, It realizes encoder 50 and signal detection is carried out to the first wheel 10 and the rotation of Second wheel 20.

As the preferred embodiment of the utility model, the present embodiment is mutually nibbled in 30 gear portion 32 of worm screw with the turbine 40 It is socketed with a plastic shell 70 at the position of conjunction, protection is sealed for the fit structure between worm screw 30 and turbine 40, Dust is placed to enter and influence the cooperation between worm screw 30 and turbine 40.

In the present embodiment, on the worm screw 30 two interconnecting pieces 32 positioned at the first wheel 10 and the inside of the second wheel 20 Position be respectively sleeved on a wheel bearing 121, described two wheel bearings 121 are arranged in the plastic shell 70 Portion, and be rotatablely connected with plastic shell 70.That is, the rotation of the present embodiment worm screw 30 can't generate plastic shell 70 It influences.And it is provided with flange part 71 on the plastic shell 70, with screw (figure between the flange part 71 and encoder 50 Do not show) it is fixedly connected, assembly of the plastic shell 70 on the wheel-type incremental-rotating coder is realized with this.
