Abstract

The gear driving device for tower-type mechanical vertical kiln includes driving gear, driven gear, toothed block and bearing support body, and the toothed block is directly mounted on the upper bearing seat of the bearing support body.

Description

Gear transmission device of cement tower type machinery vertical kiln

The utility model relates to the gear drive of the tower machine shaft kiln of a kind of cement, belongs to cement manufacture plant.

The number of patent application of submitting on January 31st, 92 with the applicant is that 92213194.5 patent application " the tower machine shaft kiln of cement material breaks handler " is as prior art of the present utility model.Fig. 1 is the topology view of prior art gear drive.Gear drive partly is made up of driving gear 1, driven gear 2 and bearing supporting mass 4 three.The bearing supporting mass comprises top chock, step and steel ball, and driven gear is made up of tooth piece 6 and wheel disc 5, the tooth piece by securing member be fixed on wheel disc around, the wheel disc of driven gear adopts securing member to be fixed on the top chock.During work, power reaches driving gear by prime mover, deceleration device and drives pallet 3 rotations that are fixed on the driven gear through driven gear.Although the transmission device that this device is commonly used has many advantages, but in production practices, find, also there is following weak point in this device: because the driven pulley wheel diameter of general tower machine shaft kiln is very big, when therefore producing, the driven pulley wheel disc all is to be made through Vehicle Processing by steel plate welding (or steel-casting) again, and the welding job amount is very big, and welding material and steel materials are a lot, its assembly precision is very high when in addition wheel disc being connected with top chock, and difficulty is bigger.Wheel disc deadweight simultaneously is very big, will cause bigger energy consumption in the course of work of equipment, in a word, the existence of wheel disc to the manufacturing of equipment and work brought artificial, material, equipment and power than lossy.

The purpose of this utility model is to provide a kind of the tooth piece is directly installed on gear drive on the top chock, thereby saves wheel disc to overcome the weak point of above-mentioned prior art.

The utility model is achieved in that the tower machine shaft kiln of cement gear drive, it is by driving gear, driven tooth gear teeth piece, bearing supporting mass are formed, driven tooth gear teeth piece be directly installed on by securing member the bearing supporting mass top chock around, the tooth piece number of driven gear is at least one.

Have installing hole around tooth piece middle part and the top chock, by securing members such as bolt, screw or pin with the tooth piece closely be installed in top chock around.

Adopt the threaded alignment pin in lower end as securing member, earlier with the tooth piece by the installation site be placed on top chock around the top, alignment pin is placed in the installing hole, by nut alignment pin is fixed again.

The tooth piece number of driven gear is one, and the tooth piece has a location open slot along the radial direction inboard is installed, and exterior bottom has circular protruding rank, and middle part, protruding rank has one screwed hole is installed.

Compared with the prior art the utility model has following advantage:

1, saved wheel disc, thereby saving of labor, material-saving, reduced manufacturing cost, the tower machine shaft kiln of often selecting for use with present manufacture of cement factory of 2.5 meters specifications of φ is an example, and one of every production can be saved about 5000 yuan of manufacturing expenses.

2, saved wheel disc, structure is simpler, compact, and it is convenient especially to install, overhaul.

3, saved wheel disc, the shaft kiln gear drive is partly conducted oneself with dignity and is reduced about about 1.5 tons, greatly reduces energy consumption, makes manufacture of cement factory benefited a great deal.

4, adopt the monodentate block structure, alleviated tooth piece weight, easy to process, the tooth piece has more versatility to various machine shaft kilns.

Below in conjunction with accompanying drawing the utility model is described in detail:

The tower machine shaft kiln of the utility model cement gear drive, it is made up of driving gear, driven tooth gear teeth piece 8 and bearing supporting mass 7, and the bearing supporting mass comprises top chock 11, step 12 and steel ball 13.The mid portion of driven tooth gear teeth piece has installing hole, around top chock, also have and the corresponding installing hole of tooth piece, pass through securing member, as bolt, screw or pin etc., with the tooth piece closely be installed in top chock around, adopt the threaded alignment pin in lower end 9 as securing member in the present embodiment, earlier with the tooth piece by position of mounting hole be placed on bearing block around the top, alignment pin is placed in the installing hole, with nut 10 alignment pin is fixed again.

The tooth piece number of driven gear is one, and the tooth piece has a location open slot (14) along the radial direction inboard is installed, and exterior bottom has circular protruding rank (15), and middle part, protruding rank has one screwed hole (16) is installed.
