Description

For the casing of the speed reducer of drum unit
Technical field
The utility model relates to transmission device field, is specifically related to a kind of casing of the speed reducer for drum unit.
Background technique
Drum unit is the common equipment of the mechanical strength for measuring coke, speed reducer inside for drum unit will be arranged usually organizes bearing more, the location of bearing is all withstood on bearing outer ring by the end cap of casing outside to position, when break changed by needs, end cap is needed to remove, break is changed complete, when reinstalling, need the gap readjusting bearing, adjustment bearing play is more loaded down with trivial details, often waste a lot of time, therefore, the bearing orientation type of the speed reducer inside to existing drum unit is needed to improve, to improve the efficiency of assembling of speed reducer inner bearing, ensure the assembly precision of bearing.
Summary of the invention
The purpose of this utility model is, for the existing speed reducer Problems existing for drum unit pointed in background technique, to provide one to be convenient to bearing assemble, and can ensure the casing of the speed reducer for drum unit of the assembly precision of bearing.
The technological scheme realizing goal of the invention of the present utility model is as follows:
A kind of casing of the speed reducer for drum unit, it comprises the body of box body of speed reducer, input shaft mounting hole is respectively arranged with relative position on right side wall at the left side wall of body, intermediate propeller shaft mounting hole and output shaft mounting hole, input shaft mounting hole is arranged on the front portion of left side wall and right side wall, intermediate propeller shaft mounting hole is arranged on the middle part of left side wall and right side wall, output shaft mounting hole is arranged on the rear portion of left side wall and right side wall, end ring fitting recess is provided with in input shaft mounting hole and intermediate propeller shaft mounting hole, the end ring for bearing location is provided with in end ring fitting recess.
In order to improve the assembly precision of bearing, the end ring in the end ring in the input shaft mounting hole on described left side wall and the input shaft mounting hole on right side wall is symmetrical arranged relative to the center line of the fore-and-aft direction of body.
In order to improve the assembly precision of bearing, the end ring in the end ring in the intermediate propeller shaft mounting hole on described left side wall and the intermediate propeller shaft mounting hole on right side wall is symmetrical arranged relative to the center line of the fore-and-aft direction of body.
The advantage of the casing of the speed reducer for drum unit of the present utility model is: the casing of the speed reducer for drum unit of the present utility model is provided with end ring respectively in input shaft mounting hole and intermediate propeller shaft mounting hole, when assembling, bearing loads in corresponding mounting hole from the inside of body, the end face outside of the outer ring of bearing withstands on end ring, carries out axially locating by end ring to bearing.By this set, the assembly precision of bearing can be ensured, and when after replacing break, when needing to ressemble, not need to adjust bearing play, save the time of assembling, improve working efficiency.
Accompanying drawing explanation
Fig. 1 is the structural representation of existing drum unit speed reducer;
Fig. 2 is the structural representation of drum unit speed reducer of the present utility model;
Fig. 3 is the structural representation of the casing of drum unit speed reducer of the present utility model;
In figure, 1 is body, and 11 is left side wall, and 12 is right side wall, and 2 is input shaft mounting hole, and 3 is intermediate propeller shaft mounting hole, and 4 is output shaft mounting hole, and 5 is end ring, and 6 is end ring fitting recess.
Embodiment
With reference to the casing of the speed reducer for drum unit shown in Fig. 2 and Fig. 3, it comprises the body 1 of box body of speed reducer, input shaft mounting hole 2 is respectively arranged with relative position on right side wall 12 at the left side wall 11 of body 1, intermediate propeller shaft mounting hole 3 and output shaft mounting hole 4, input shaft mounting hole 2 is arranged on the front portion of left side wall 11 and right side wall 12, intermediate propeller shaft mounting hole 3 is arranged on the middle part of left side wall 11 and right side wall 12, output shaft mounting hole 4 is arranged on the rear portion of left side wall 11 and right side wall 12, end ring fitting recess 6 is provided with in input shaft mounting hole 2 and intermediate propeller shaft mounting hole 3, the end ring 5 for bearing location is provided with in end ring fitting recess 6.
In order to improve the assembly precision of bearing, in the input shaft mounting hole on described left side wall 11 2 end ring 4 and the input shaft mounting hole on right side wall 12 in 2 end ring 5 be symmetrical arranged relative to the center line of the fore-and-aft direction of body 1.
In order to improve the assembly precision of bearing, the end ring 5 in the intermediate propeller shaft mounting hole 3 on described left side wall 11 is symmetrical arranged relative to the center line of the fore-and-aft direction of body 1 with the end ring 5 in the intermediate propeller shaft mounting hole 3 on right side wall 12.
Speed reducer of the present utility model is when assembling, and bearing loads in corresponding mounting hole from the inside of body 1, and the end face outside of the outer ring of bearing withstands on end ring 5, carries out axially locating by end ring 5 pairs of bearings.By this set, the assembly precision of bearing can be ensured, and when after replacing break, when needing to ressemble, not need to adjust bearing play, save the time of assembling, improve working efficiency.
Above embodiment is the explanation to embodiment of the present utility model; but not to restriction of the present utility model; person skilled in the relevant technique is not when departing from spirit and scope of the present utility model; can also make various conversion and change and obtain corresponding equivalent technological scheme, therefore all equivalent technological schemes all should be included into scope of patent protection of the present utility model.
