Description
Technical field:
The utility model relates to the roll gap adjustment device of roll in a kind of hot-rolling mill, specifically is the encoder installing rack in a kind of roll gap adjustment device.
Background technology:
Before the hot mill rolling steel band, in order to obtain certain thickness rolled piece, the direct labor can adjust the roll gap between two rolls by screwdown gear usually in advance, in the process of adjusting roll gap, the encoder installed in the screwdown gear can be real-time the displacement of record two rolls, thereby make the direct labor can control roll gap size between two rolls accurately.Encoder in the conventional screwdown gear generally is installed on the encoder installing rack, as shown in Figure 2, this encoder installing rack comprises screwdown gear end cap 105, encoder cover 104, encoder cover cap 106, be used to the base 101 the installing plate 102 of splined shaft 103 being installed and being used to install encoder 100, base 101 is connected with encoder cover cap 106 with installing plate 102, encoder cover cap 106 is connected with encoder cover 104, encoder cover 104 is connected with screwdown gear end cap 105, the rotating shaft of encoder 100 is connected with splined shaft 103 by connecting spring shaft 107, there are following two weak points in above-mentioned encoder installing rack in actual application: 1, base 101 is located inaccurate with installing plate 102 and installing plate 102 in assembling process with encoder cover cap 106, base 101 and installing plate 102 easily when the bolt jam-packed and encoder cover cap 106 mutual dislocation take place, thereby rigging error occurs, influence the rotating shaft of splined shaft 103 and encoder 100, the axiality of encoder cover cap 106; 2, encoder cover 104 is located inaccurate in assembling process with screwdown gear end cap 105, encoder cover 104 easily when the bolt jam-packed and screwdown gear end cap 105 mutual dislocation take place, thereby rigging error occurs, and then influence the axiality of splined shaft 103 and screwdown gear end cap 105.
The utility model content:
The technical problems to be solved in the utility model is, provides a kind of and can effectively avoid rigging error, guarantees the encoder installing rack in the hot-rolling mill screwdown gear of splined shaft and encoder rotating shaft, encoder cover cap and screwdown gear end cap axiality.
Technical solution of the present utility model is, provide the encoder installing rack in a kind of hot-rolling mill screwdown gear with following structure: comprise the screwdown gear end cap, the encoder cover, the encoder cover cap, be used to the base the installing plate of splined shaft being installed and being used to install encoder, the encoder cover cap is connected with the encoder cover, wherein, installing plate is provided with the first location shaft shoulder, base is stuck on the first location shaft shoulder, the encoder cover cap is provided with the second location shaft shoulder, installing plate is stuck on the second location shaft shoulder, the screwdown gear end cap is provided with the 3rd location shaft shoulder, and the encoder cover is stuck on the 3rd location shaft shoulder.
Encoder installing rack in the hot-rolling mill screwdown gear described in the utility model wherein, can be equipped with on the splined shaft and is used to prevent the make progress jump ring of play of splined shaft, and jump ring is positioned at the installing plate bottom.
Encoder installing rack in the hot-rolling mill screwdown gear described in the utility model can be provided with cushion cover between jump ring and the installing plate.
After adopting above structure, compared with prior art, encoder installing rack in the utility model hot-rolling mill screwdown gear has the following advantages: with the prior art base, there are the rigging error difference in installing plate and encoder when covering on assembling, the utility model is except being provided with the first location shaft shoulder on installing plate, also on encoder cover cap and screwdown gear end cap, be respectively equipped with the second location shaft shoulder and the 3rd location shaft shoulder, therefore, work as base, when installing plate and the assembling of encoder cover, the first location shaft shoulder, the second location shaft shoulder and the 3rd location shaft shoulder can be respectively to bases, installing plate and encoder cover position, in other words, in case the encoder cover is stuck in the 3rd location shaft shoulder, installing plate is stuck in after second the location shaft shoulder and the base be stuck in the first location shaft shoulder, their positions each other will be fixed under the effect of the corresponding shaft shoulder, like this, just the mutual dislocation phenomenon can not take place, thereby effectively guaranteed splined shaft and encoder rotating shaft in the process of their assemblings, the axiality of encoder cover cap and screwdown gear end cap.
Because splined shaft has a centrifugal force that makes progress when rotating at a high speed, i.e. the splined shaft play that makes progress, centrifugal force can push away the encoder that is connected with base when big, and the setting of the utility model jump ring can effectively prevent the splined shaft play that makes progress.
