Abstract
The utility model discloses a piston motor which comprises a casing, a piston and a crankshaft, wherein one end of the crankshaft is inserted into the casing and connected with a connection rod of the piston through a cam, and a bearing is arranged between the crankshaft and the casing. The piston motor is characterized in that a flange is arranged on the crankshaft and outside the casing, and the outer diameter of the flange is larger than the inner diameter of the casing. The output part of the crankshaft is isolated outside the casing through the flange arranged on the crankshaft, so that the crankshaft does not axially move in the casing when a gear is arranged, and displacement between the crankshaft and the connection piston of the piston is avoided. Therefore, the piston transfers kinetic energy to the crankshaft through the cam to enable the crankshaft to rotate normally.
Description
Technical field
The utility model relates to a kind of improvement invention of piston type motor.
Background technique
Piston type pneumatic motor is that employing pressurized air is the energy; Gas from the housing front suction port through the distribution cover, be assigned to each cylinder; Promote piston motion, pass to bent axle output speed and power through weighted cam again, former installation method can only insert from the housing rear end, passes the distribution cover; The bearing front end can only be located with back-up ring, and is axially displaced easily when stressed.Install with close-fittings such as gear or sprocket wheel, belt pulleys because the output axle head is required.During installation, need beat and could required installation material case be contained on the bent axle, and when beaing; The impact force that bent axle can be beaten, and in housing, move axially, make the connecting rod of bent axle and piston produce displacement; Thereby cause the power of piston not run well, causes crankshaft can not be rotated, and existing bent axle and cam are connected as a single entity; Make processing difficulties, cost of material and cost of production are higher, and very inconvenience is installed.
Summary of the invention
In view of the existing technical problem of background technique, the utility model technical problem to be solved provides a kind of bent axle when mounted and can not move axially, and easy processing, piston type motor that cost of production is lower.
In order to solve the problems of the technologies described above, the utility model adopts following technological scheme to realize: this kind piston type motor includes housing, piston and bent axle; One end of said bent axle inserts in the housing; And this end of said bent axle is connected with the connecting rod of piston through cam, is provided with bearing between said bent axle and the housing, it is characterized in that said bent axle is provided with flange; Said flange places outside the housing, and the external diameter of said flange is greater than the internal diameter of housing.
Said bent axle is connected with cam bolt.
The utility model is provided with flange on bent axle; Be isolated in outside the housing through the output of flange bent axle; When gear was installed, bent axle just can not produce in housing and move axially like this, thereby can not produce displacement with the connecting rod of piston yet; So piston passes to bent axle with kinetic energy through cam, makes the bent axle normal rotation.Said bent axle is connected with cam bolt, and bent axle and cam are processed comparatively easy respectively, and easy for installation, have alleviated labor intensity, have reduced cost of production.
Description of drawings
Further describe the working principle and the relevant details thereof of the utility model below in conjunction with accompanying drawing.
Fig. 1 is the structural representation of the utility model.
Embodiment
With reference to accompanying drawing, this kind piston type motor includes housing 3, piston 5 and bent axle 1; One end of said bent axle 1 inserts in the housing 3, and this end of said bent axle 1 is connected with the connecting rod 6 of piston through cam 4, and said bent axle 1 is connected with cam 4 bolts; Be provided with bearing 2 between said bent axle 1 and the housing 3; Said bent axle 1 is provided with flange 8, and said flange 8 places outside the housing 3, and the external diameter of said flange 8 is greater than the internal diameter of housing 3.
When said bent axle 1 is installed gear, bent axle 1 axially loaded, but stopping owing to flange 8; Avoided bent axle 1 moving axially in housing 3; Thereby when gear was installed, the position between bent axle 1 and the connecting rod 6 can not change, bent axle 1, cam 4 and connecting rod 6 three's position stabilities.Said bent axle 1 is connected with cam 4 bolts to make easier for installationly, and processes conveniently, has saved cost of material and cost of production.
