【正文】 推理和論證，設(shè)計了耙斗裝巖機的減速器 工作滾筒 空程滾筒等絞車主要部件。行星齒 輪和相鄰的太陽輪、齒圈總是處于常嚙合狀態(tài)，通常都采用斜齒輪以提高工作的平穩(wěn)性 當(dāng)行星架為主動件時，從動件超速運轉(zhuǎn)。 若行星架作為被動件，則它的旋轉(zhuǎn)方向和主動件同向。 ） 若行星齒輪機構(gòu)中的任意兩個元件同速同方向旋轉(zhuǎn)，則第三元件的轉(zhuǎn)速和方向必然與前兩者相同，即機構(gòu)鎖止，成為直接檔。 齒圈固定，太陽輪為主動件且順時針轉(zhuǎn)動，而行星架則為被動件。這樣，太陽輪帶動行星架轉(zhuǎn)動仍屬于小齒輪帶動最大的齒輪，是一種減速運動且有最大的傳動比。由于行星架是一個當(dāng)量齒數(shù)最大齒輪，因此被動的齒圈以增速的方式輸出，兩者間傳動比小于 1。在定 軸傳動中，行星輪起了過渡輪的作用，改變了被動件齒圈的旋向。但體積大，鋼絲繩磨損快。s principle of work According to the law of conservation of energy, three ponents on the input and output power of algebra and should be equal to zero, and get a single pla gear institutions in general the law of motion of the characteristic equation. Characteristic equations: n1 + an2(1 + a) = 0 n3 by characteristic equation can see, because odd pla gear mechanism possesses two degrees of freedom, in the sun, ring round in circles and pla shelf teeth three institutions, choose two respectively, as an active and a follower, and make another ponent fixed, or their movement under certain constraints (namely the ponents of the speed for a fixed value), the agency only a degree of freedom, the gear at a certain ratio transfer power. Here are three of the discussion. 1, tooth circle fixed, the sun round to active thing and clockwise and pla shelf is passive one. The sun round clockwise, the sun wheel gear will give A pla gear A thrust F1, is the pla round should rotate counterclockwise (6), but because the tooth circle fixed, so tooth gear plaary gear to circle will B A reaction which F2, the pla round in F1 and F2 force under the action of will revolves around the sun in wheel clockwise, result the pla round exists not only counterclockwise rotation, and in the pla shelf to lead, revolves around the sun in the central axis round clockwise revolution. In this state, appeared plaary gear transmission mode in the role of the agencies, and passive a pla shelf direction of rotation and active but thing. Here, the sun round is active and is a small gear, passive a pla shelf no specific number of transmission relations, and therefore define pla shelf equivalent is equal to the number of the sun wheel and tooth circle of number. So, the sun wheel drive the pla shelf rotation is still belongs to a small gear drive the biggest gear, is a kind of slow motion and has the largest transmission. 2, the sun wheel is fixed, the pla shelf for active and a clockwise circle for passive a tooth. When the pla A chronological turns, would cause the pla round clockwise rotation, but because the sun wheel brake, the sun to pla gear teeth gear B A reaction which F1, the pla round in F1 under the effect of rotating clockwise, the gear tooth gear to circle A A F2 thrust, tooth circle in the F2 under the effect of rotating clockwise. Here, the initiative a pla shelf and the direction of rotation Move a tooth circle the same. Due to the pla shelf is a equivalent maximum number of gear, so passive tooth round the output growth way between transmission ratio less than 1. Because the n1 = 0, the transmission ratio i23 = n3 / n2 = a / (1 + a). 3, Pla shelf fixed, the sun round to active thing and clockwise and tooth circle is taken as a passive one. Due to the pla shelf are fixed, the agency will belong to set
