Pengaruh Variasi Jumlah Gigi Wheel terhadap Perbandingan Kontak serta Kecepatan Luncur Spesifik untuk Jumlah Gigi Pinion Minimum

Abstract: At the point of contact with the pinion and wheel surface contour of each involut produce different tangential velocity direction and magnitude, consequently normal component as sliding velocity will be different as well so as to produce friction or glide. This study looked at the effect on the speed of specific sliding pinion and gear wheel on a pair with a standard tooth profile involut fulldepht the pressure angle  gear module m on the condition minimum number of theoretical pinion tooth N wheel tooth number variation N 2 . The implementation of simulation research using Excel. Maximum specific sliding speed pinion occur at the initial point of contact K 2 275 1 module m = 5mm, pressure angle  = 32 and number of teeth N 2 = 4 wheel drive conditions under which p  = -165,150 at the point of escape/retreat contact K 1 on the same parameters K2 p  = 0.5084. The specific slidding velocity maximum wheel occurs at the point of contact K K1 at the module off m = 1.5 mm, angle = 10   press and N 2 1 = number of teeth wheel drive 46 under the condition that w  = -119.808 minimum occur at the same parameters in the initial point of contact K K1 2 w  = 1.

Design and analysis of cam mechanism with translating follower having double rollers

Abstract: The pressure angle is one of the primary considerations in designing a cam mechanism since an inappropriate angle may cause excessive sliding loads on the follower. This paper presents a simple yet...

Small-modulus small-tooth-number spiral bevel gear powder metallurgy process

Abstract: The invention discloses a small-modulus small-tooth-number spiral bevel gear powder metallurgy process. The process comprises the following steps that the structure of a spiral bevel gear is determined by adopting a three-dimensional digital-to-analogue mode, and the shape of a relevant contact area and transmission noise are tested under a meshing simulation state; proportional power is pressed and formed after a spiral angle and a pressure angle of the spiral bevel gear are modified; and a pressed and formed part is put in a closed furnace for sintering, an inner hole and the end surface aremachined, and finishing treatment is conducted on the part. According to the process, the advanced powder metallurgy process is adopted, so that the small-modulus small-tooth-number powder metallurgyspiral bevel gears with complex structures can be produced in an industrialization large-scale manner, the surfaces are smooth, the noise during meshing is small, the density of product tooth parts is uniform, the manufacturing cost is low, and the large-scale production and use requirements can be met.

Abstract: The invention relates to a pressure angle attitude control mechanism for an eight-legged crawling robot. The pressure angle attitude control mechanism for the eight-legged crawling robot comprises a fixed plate and is characterized in that a proportional pressure reducing valve and a long cylinder are fixed on the fixed plate; a piston rod of the long cylinder is connected with a movable joint; the movable joint is connected with a movable joint seat; the movable joint seat is fixed on a middle layer sliding plate; a pressure control cylinder is fixed on the middle layer sliding plate; a piston rod of the pressure control cylinder is connected with an upper layer sliding plate; the upper layer sliding plate is in sliding fit with the middle layer sliding plate; a pressure seat is fixed onthe upper layer sliding plate; the pressure seat is fixed together with a sensor seat; a cutter breaking detection sensor is tightened in a hole of the sensor seat; an air inlet end of the proportional pressure reducing valve is connected with an air supply hole via an air pipe; and an outlet of the proportional pressure reducing valve is connected with an upper air inlet of the pressure control cylinder through an air pipe. According to the pressure angle attitude control mechanism for the eight-legged crawling robot, through combined control of a double-layer executing mechanism, all functions of freely switching, executing and so on of a pressure angle among a machining state, a running state, a cutter changing state and a cutter detection state are realized.

A Study on Conceptual Design of Planocentric Involute Reducer for Modular Robot

Abstract: This paper presents a geared drive on joints of a modular robot using the planocentric involute gearing mechanism. Unlike the typical harmonic drive or cycloid drive those have significant disadvantages in designing and manufacturing, this paper describes it with the replaceable mechanism which has a customized involute gearing design to maximize a speed reduction rate and to avoid the tooth tip interference. In connection with it, the design parameters; pressure angle, tooth height, profile shifting factor and number of teeth are simulated to meet the specific usage as a joint drive of the modular robot. Since the planocentric involute gearing is applied to the joint drive, this can make advantages of easiness of machining and assembling the gears. For a case study as its application, the geared drive; planocentric involute reducer is conceptually designed for a joint module of the modular robot.
