Abstract
The utility model discloses a pulley device of a 10T steel tackle. The pulley device of the 10T steel tackle comprises a pulley (1) which is penetrated through by a pin (6). The pulley device of the 10T steel tackle is characterized in that the pulley (1) is connected with the pin (6) through a bearing (2), bearing blocking covers (3) are arranged on two sides of the bearing (2), and check rings (4) are arranged between the bearing blocking covers (3) and pulley blocking covers (5). According to the pulley device of the 10T steel tackle, gaps of the pulley and side boards are reduced, the sealing property is better, moreover, production cost is lowered, a copper sleeve is changed into two sets of bearings, abrasion is reduced, working is more reliable and stable, noise does not exist, the service life of the pulley is prolonged, the pulley is made of cast steel rather than cast iron, tensile strength is enhanced, heavy articles which are over 11T can be lifted, and production efficiency is improved.
Description
Technical field
The utility model relates to a kind of weight bont, relates in particular to a kind of for the pulley gear that promotes the 10T weight.
Background technology
Common 10T pulley, the gap of its pulley and side plate is bigger, has caused the waste of material, seals bad; What connect the use of pin and pulley is copper sheathing, not wear-resisting; The making material of pulley is cast iron, and mechanical property shows as hard and crisp, bad processing, and tensile strength is low, causes it fragile, and the life-span is low.
Summary of the invention
The technical problems to be solved in the utility model: a kind of novel 10T iron block pulley gear is provided, bigger to solve conventional gap with pulley and side plate, caused the waste of material, seal bad; What connect the use of pin and pulley is copper sheathing, not wear-resisting; The making material of pulley is cast iron, and mechanical property shows as hard and crisp, bad processing, and tensile strength is low, causes it fragile, has reduced the problems such as service life of pulley gear.
Technical solutions of the utility model:
A kind of 10T iron block pulley gear, it comprises that pulley is run through by pin, and pulley is connected with pin by bearing, and the bearing both sides are provided with the bearing door, are provided with back-up ring between bearing door and pulley door.
The material of pulley is cast steel.
The beneficial effects of the utility model:
The utility model 10T pulley gear has reduced the gap of pulley and side plate, make its better tightness, change the copper sheathing that plays the slip effect into 2 cover bearings, make pulley work reliable more, steadily, noiseless, pulley changes cast steel into by cast iron, and its tensile strength is improved, and the gap that has solved conventional pulley itself and side plate is bigger, caused the waste of material, sealed bad; What connect the use of pin and pulley is copper sheathing, not wear-resisting; The making material of pulley is cast iron, and mechanical property shows as hard and crisp, bad processing, and tensile strength is low, causes it fragile, has reduced the problems such as service life of pulley gear.
Description of drawings:
Fig. 1 the utility model scheme drawing.
The specific embodiment:
Embodiment: a kind of 10T iron block pulley gear; it comprises (see figure 1) pulley 1, pin 6, bearing 2; at pin 6 and 1 on pulley two cover bearings 2 are installed; pulley is played supporting and slip effect; bearing 2 outsides have bearing door 3 to be sealed and protect; separate two doors 5 of bearing door 3 and pulley doors with back-up ring 4, nut is connected with pin 6, finishes the connection of whole pulley.
The utility model 10T iron block pulley gear has reduced the gap of pulley 1 with side plate, make its sealing property better, and reduced productive costs, and change copper sheathing into two cover bearings 2, reduced wearing and tearing, make its work reliable more, steadily, noiseless, prolonged the service life of pulley 1, the material of pulley 1 changes cast steel into by cast iron, has strengthened its tensile strength, can promote the above weight of 11T, improve production efficiency.
Claims (2)
